Canec

Between 1879 and 1948, Waiākea Mill Company conducted mill operations at Waiākea Pond. Bagasse – a by-product of sugarcane – became a secondary industry, first as a fuel for the mills’ boilers, then as the main ingredient for a wallboard product.

As commercial fuel oils became increasingly available in the late 1920s, the use of bagasse as a fuel declined. This byproduct of production was then creatively used to manufacture a wallboard product for construction.

In 1929, Hawaiian Cellulose Ltd, a subsidiary of the Waiākea Mill Company applied for a patent for the manufacture of it. (County of Hawai‘i)

On May 23, 1930, “The leading plantation agencies and a group of business men organise a $2,250,000 corporation for the manufacture of wallboard and other universally used bagasse fiber products. The name chosen was the Hawaiian Cane Products, Limited.” (The Friend, June 1930)

Later that year, the directors of the company “authorized the purchase of a one-hundred-ton daily capacity plant for the manufacture of insulating board from bagasse.” (The Friend, October, 1930) (It ended up costing $2.5-million.)

April 27, 1932, the company’s Hilo plant (at Waiākea, adjoining Wailoa Pond) was opened; the company emphasized “the overseas distribution for which the industry aims.” (The Friend, June 1, 1932) (By 1934, “five carloads were shipped … to Manchuria.” (Friend, July 1, 1934))

Canec was originally the brand name for pressed fiber board made by Hawaiian Cane Products, Ltd., but it has become commonly used to refer to all pressed board of this type.

It was formed into sheets similar in size to drywall, as well as other sizes for use as ceiling and wallboard. Canec was used for interior ceilings and walls in many residential and commercial structures throughout the state of Hawai‘i. (DOH)

Reportedly, Charles William Mason, a Scotsman who ended up in Olaʻa on the Island of Hawai‘i in 1919, was the inventor of Canec. Mason became the superintendent of Hawaiian Cane Products Company, Ltd., located in Hilo near the site of the Waiākea Mill Company. (Johnston)

The use of canec as a building material in Hawai‘i gradually expanded during the 1930s, but greatly accelerated after World War II when construction volume rapidly increased.

It was estimated that from the twelve plantations contributing bagasse to the canec plant, one million tons of bagasse would be available for the production of wallboard.

Hawaiian Cane Products was sold to the Flintkote Company in 1948. That year, the Hilo plant manufactured 120,000,000-square feet of canec panels; from 1945 to 1955; the majority of the housing in the Islands featured cane walls and/or ceilings. (HHF)

The original patent for canec wallboard called for the bagasse to be mixed with hydrated lime, caustic soda, soda ash and similar chemicals to digest fiberous portions of the trash. (Bernard)

It was treated with inorganic arsenic compounds to discourage mildew and insects. In addition, the wallboard was treated against termites with calcium arsenate and arsenic, and finally hydrosulfate was added to ‘set the size,’ inhibit the absorption of water and harden the board. (Bernard)

The canec plant discharged its waste through a sewer pipe that emptied into the water at the point where the pond flows into Wailoa River.

A NOAA report says, “An estimated 558-tons of arsenic compounds were released into the Hilo Bay estuary through this sewer line during the operational history of the plant.” (EH)

As was disclosed to the public in 1973, the canec plant had “discharged approximately 3.5-mgd of waste water into the Wailoa estuary for 29-years”.

This waste water included both toxic and lethal chemicals such as arsenic, hydrated line, hydrosulfate, ethyl silicate, hydrosulfate, calcium, arsenate and arsenic acid. (Bernard)

Arsenic concentrations in the sediments of Hilo Bay have been found to be as high as 6,370-ppm, approximately 34 times higher than anywhere else in the state (Department of Health.) (Hallacher)

Some suggest the canec plant was destroyed by the May 23, 1960 tsunami that devastated Hilo; actually, a fire destroyed the canec plant a month earlier (April 3, 1960.)

In 1971, the hotel complex known now as Waiākea Villas was built on the canec plant site (the adjacent Waiākea plant millpond was made part of Wailoa River State Park.)

“Although elevated in comparison to natural background, inorganic arsenic in canec material does not pose exposure or potential health concerns for building residents or workers, provided that the canec is in good condition and not rotting or ‘powdering away.’”

“No health effects caused by short time (acute) exposure to high levels of arsenic in canec, or to lower concentrations for a long time (chronic exposure) have been reported to HDOH.”

“However, daily exposure to very high levels of inorganic arsenic over many years can result in various health effects, including an increased risk of cancer. As a result, exposure to deteriorating canec should be minimized.” (Department of Health)

Waikapū

Maui is the second largest of the Hawaiian Islands, and covers about 730 square miles. Maui consists of two separate volcanoes with a combining isthmus between the two.

The Mauna Kahālāwai (West Maui Mountain) is probably the older of the two; Haleakala (East Maui) was last active about 1790, whereas activity on West Maui is wholly pre-historic.

The island of Maui is comprised of 12-moku (districts,) that are made up of a number of ahupuaʻa. The moku of Wailuku makes up an area known as Nā Wai ʻEhā (“The Four Great Waters”) – Waiheʻe River, Waiehu Stream, Wailuku (ʻĪao) Stream and Waikapū Stream. (Waikapū Stream is the only Nā Wai ‘Ehā stream that drains to the southern coast of Maui.)

“From Waiheʻe to Waikapū there is much good land below and bounding the ancient terrace area on the kula and in the lower valleys which would be ideal for sweet potato culture, but it is said that little was grown in this section because there was so much taro.” (Handy; Hana Pono)

“For generations the small, slowly growing population clustered around shore sites near streams that supplied them with water. Such sites are best for inshore fishing.”

“When they acquired taro, they no doubt rapidly cleared away the jungle along the streams to make room for taro patches, and there was a beginning of terraced flats that could be irrigated directly from the stream.” (Handy; Hana Pono)

The fertile kalo terraces, complex system of irrigation ʻauwai (ditches) and abundant fresh water from this area sustained Hawaiian culture for 1,000-years. Due to abundant water and fertile lands, there was substantial settlement between the 300- and 600-foot elevation at Waikapū.

The terraces were irrigated with water brought in ditches from springs and streams high in the valleys, allowing extensive areas of the valleys to be cultivated. The irrigation ditches and pondfields were engineered to allow the cool water to circulate among the taro plants and from terrace to terrace, avoiding stagnation and overheating by the sun, which would rot the taro tubers.

An acre of irrigated pondfields produced as much as five times the amount of taro as an acre of dryland cultivation. Over a period of several years, irrigated pondfields could be as much as 10 or 15 times more productive than unirrigated taro gardens, as dryland gardens need to lie fallow for greater lengths of time than irrigated gardens. (Kelly)

In Waikapū, there are different stories associated with the name of this valley and ahupuaʻa; the story of Puapualenalena and the conch shell may be the earliest known.

It was said that in ancient times a conch shell would ring out from the valley, heard around the island it was so loud and resounding. On the opposite, northern side of the stream a dog named Puapualenalena was infatuated with this conch and wanted it for himself.

One day, the owners of the conch had been careless and Puapualenalena gained entrance to the cave on the southern side of the stream that hid the conch, and from that point on it no longer sounded through the valley. The area was so named for the conch (Pu), The Water (Wai) of the Conch (Ka Pu.) (Nupepa Kuokoa, 1872; Hana Pono)

Some say the name comes from Kamehameha after the famous battle of Kepaniwai, when the defeated the forces of Kalanikūpule. Two versions are told.

One is Wai-ka-pu (the Water of the Conch,) for the place where Kamehameha sounded the Pu to begin the battle for Maui. The second is Wai-Kapu (the Sacred Water.) “Kamehameha landed at Kalepolepo, and a kapu was put upon the nearest stream. It became sacred to royalty, as was the custom and is known as Wai-kapu to this hour-that is, the forbidden water”. (Stoddard; Hana Pono)

The lower isthmus (between Mauna Kahālāwai and Haleakala) was sandy. “We passed through Waikapū in the middle of the isthmus …. Between this place and the northern shore, we walked over a bed of sand (a part of an extensive plain).” (Bingham)

In more modern times, the Waikapū ahupuaʻa and surrounding lowlands were given to Henry Cornwall for a sugar plantation, Waikapū Sugar Company, which eventually merged with others to become Wailuku Sugar Company (and later consolidated into the Alexander & Baldwin lands.).

Starting in about the 1850s, sugar cultivation destroyed the extensive terracing; by the mid-1900s, only remnant representations remained.

By 1866, a letter published in the Hawaiian language newspaper Nūpepa Kūʻokoʻa lamented “the current condition of once cultivated taro patches being dried up by the foreigners, where they are now planting sugar cane”.

“A permanent railroad was laid to Waiheʻe and to Waikapū connecting at Wailuku, from whence the cane was carried to a mill above Kahului. Another permanent line connected the other plantations. From these portable lines were laid into the fields, and it was thus possible to dispense with hundreds of mules and cattle and drivers heretofore used.” (Girvin)

Garden Contest

“Impressed with the barrenness of plantation camps, Mr (Frank S) Scudder (editor of The Friend) arranged for a supply of government seeds and shrubs. He then offered prizes … In a few months’ time, districts without grass or trees were converted into what, comparatively speaking, might well be termed veritable beauty spots.” (The Friend, February 1, 1917)

“We desire to furnish plantation laborers with fruit seed so they can have fruit in their own dooryards. If you have fine mangoes, or aligator pears, don’t throw away the seeds, keep them and let us have them to distribute. Any fine strawberry guavas? or any suggestions as to other fruits that can be easily raised?”

“Our ears are open to suggestions as to ways in which hardworking people, without much restful leisure, may be led to improve their home surroundings—to make the camps more delectable places to live in. Any suggestions as to flower or decorative plants? The Friend will be glad to receive Seed Thoughts.” (The Friend, February 1, 1911)

“In 1909 we planned a tree planting campaign. Mr. Ralph W. Hosmer, superintendent of forestry, kindly agreed to raise 2000 trees for free distribution in the camps.”

“The To mo – a Japanese magazine published by the Hawaiian Board – to add zest to the competition, offered four prizes for the best results in tree culture which could be attained in one year. Mr BD Baldwin, of Makaweli, offered $25 in prizes for his plantation.”

“Arbor Day, 1909, was set as the day for delivering and planting the trees. … The awarding of prizes was a delicate task. Some contestants had excelled in securing artistic effects, some in producing the finest trees and some in attaining remarkable results in spite of serious handicaps.”

“The consequence was that instead of giving five prizes as at first promised, the judges had to award eight second prizes as the only possible way out of their dilemma.”

“The writer was so perplexed that his dreams were disturbed by visions of trees and prizes and judges, and he chose as the subject of his prize awarding address the words, ‘I see men as trees, walking.’ The saplings, when set out on Arbor Day, 1909, averaged about 8 inches in height. At the close of the contest Dec. 31, 1910, they ranged from 6 to 15 feet.” (The Friend, March 1, 1911)

“Improved conditions throughout the plantation camps of the islands may be said to be a byproduct of this initial attempt to interest the people in producing a prize winning garden.” (The Friend, February 1, 1917)

Then, the Star-Bulletin sponsored the contest. In January, 1917, the Honolulu Star- Bulletin began an interesting experiment in the form of a school and home garden contest in cooperation with the school department, offering a series of prizes for the best gardens on each of the islands. (Kuykendall)

“With greater financial backing and a more elaborate publicity campaign, the Star-Bulletin can hardly fail to get results. Interest in school gardens has a direct bearing upon the much-mooted question of the small farmer in Hawaii. We bespeak for the campaign a well merited success.” (The Friend, February 1, 1917)

At the close of the contest, three months later, the Star-Bulletin said, with pardonable enthusiasm, “This garden contest has been a remarkable eye-opener, not only to the teachers and pupils, but even to the agricultural experts here, an eye-opener in proving how quickly boys and girls can be trained to raise edible and marketable produce.”

“As a result of this contest, not less than 5,000 boys and girls in Hawaiʻi are becoming producers – are becoming practical gardeners. Twice that number are interested in the gardening.” (Kuykendall)

The Honolulu Advertiser generously acknowledged the good results of this contest, stating that “the management of the Star-Bulletin has, apparently, hit upon a scheme which has accomplished much and promises more. …”

“The best part of the project is that it demonstrates to those who need the knowledge, that vegetables can be produced in all parts of the Territory, if proper care and attention is given them. … The Advertiser congratulates the Star-Bulletin upon the success of its public spirited efforts which are doubly beneficial at this crisis when food production may become one of the vital issues of the day.” (Kuykendall)

“So successful the home and garden contests recently conducted by the Honolulu Star-Bulletin, and so urgent has been the demand for continuation of the work for which the foundation already has been laid, this paper has decided repeat the contests during the coming school year.” (Star-Bulletin, August 17, 1917)

“The Star-Bulletin contest is a splendid thing both in attracting the attention of the public to the subject and in reaching in a practical and effective way those who, I believe, have the first right to be and ought to be encouraged to be, the future farmers in the Islands – the children born in the land.”

“I am afraid that I have but little sympathy with the idea of encouraging white farmers from the mainland to come to Hawaii.”

“In addition to this work of encouraging the boys and girls to look forward to life on the farm, which the Star-Bulletin is so splendidly helping along, there is need of providing a decent opportunity for them when they are ready to go on the land, and of surrounding their life there with conditions conducive to success and contentment.”

“However, there is cause for much encouragement too. Behind one of the most important measures is the splendid backing of Mr CH Cooke and Mr HA Baldwin, which ensures its passage.” (Edwin C. Moore, Hawaii Agricultural Experiment Station, Star-Bulletin, January 24, 1917) The contest continued for a few more years.

An interesting side note related to the Garden Contest came from a report by J Vincent, Principal of Kealahou School in Kula, “For years the Kula farmers have planted small plots to onions but from any seed they happened to purchase in five-cent jackets in our local stores and no special variety was even thought of.”

“This spelled failure end the majority of our farmers had come to the conclusion that onions could not be successfully grown in Hawaii.”

“Our school experimented with a number of varieties but did not have much success until a representative from Aggeler & Musser (Seed) Company called on us and recommended that we plant Bermudas, which we did.” (Bermuda is a variety of sweet onion.)

“We then succeeded in raising a fair crop and in a remarkably short time, as Bermudas mature very early. The farmers became enthusiastic and purchased over 50 pounds of seed. They also raised a fine crop ….” (Star-Bulletin, April 14, 1917)

John Meirs Horner

“’You have no wheat here, your share was destroyed by elk, antelope, and other wild animals….’ So we got nothing for our labor. Thus ended my first year’s farming in California.” (Horner)

Whoa, let’s look back …

John Meirs Horner was born on a New Jersey farm June 15, 1821. He attended the public schools and later worked on farms in the summers and taught school in the winters.

“I had been wrought up over the subject of religion. The Methodists were the most persistent in my neighborhood and my preference was for them. In these days came ministers of a new sect calling themselves Latter-day Saints, with a new revelation preaching the gospel of the New Testament with its gifts and blessings.”

“It attracted much attention, people listened and some obeyed thereby enjoying the promised blessing. Members of the Methodist, Baptist and Presbyterian faith as well as non-professors began to join them. Among the latter class were my father, mother and sisters”

“I was the first of the family to obey being baptized by Erastus Snow in the Layawa Creek on the second day of August 1840. In the spring of 1843, … I was introduced to and shook hands with the Prophet Joseph Smith.” (Horner) In 1846 he married a neighbor’s daughter, Elizabeth Imlay.

They headed west.

“The day finally arrived for the Brooklyn to set sail. The wharf was crowded with friends and relatives bidding their good-byes.”

“The Brooklyn set sail and left the New York harbor with 238 passengers including 70 men, 68 women and 100 children. … They took with them agricultural and mechanical tools for ‘eight hundred men,’ a printing press, two milk cows, forty pigs and a number of fowls. Also brought onboard were school books, histories, slates, and other school materials.” (Horner)

Yerba Buena (now known as San Francisco) was their destination, and they arrived there by way of New York, Cape Horn, Juan Fernandez Island and the Hawaiian Islands. It took 6-months and they covered 18,000-miles. The population of Yerba Buena was said to be forty; their company of 268 made an addition to their number of over 600%.

War was raging between Mexico and the US when they arrived in California. The upper part of the territory was already in possession of the US forces. After about 30-days, Horner moved to farm 40-acres of wheat on the lower San Joaquin.

Despite the early quote related to his farming experience, he turned that failure into future success. “Although I got no dollars out of it, I did get experience, which I profited by in after years. I had tested the soil in different places, with several different kinds of farm products and learned the most suitable season for sowing and planting.”

As a pioneer in agriculture, he furnished fresh vegetables and grain to the gold-crazed miners and the people of the growing city of San Francisco, as early as 1849. He fenced and brought under production many hundreds of acres, established a commission house in San Francisco for the sale of produce in 1850, imported agricultural implements from the east and iron fencing from England and built a flour mill.

He became known as “The Pioneer Farmer of California,” “California’s First Farmer” and, due to a speculative real estate venture, “Father of Union City.”

He also acquired part of Rancho San Miguel; it’s now known as Noe Valley in San Francisco. Horner’s Addition still carries some of the streets and names he laid out (among others, Elizabeth is for his wife and Jersey is for the place he was born.)

In the course of his operations, he opened sixteen miles of public road, operated a steamer and a stagecoach line, laid out no fewer than eight towns, built a public schoolhouse, and paid for the services of a teacher.

Missionaries and other brethren traveling through the area always received kind and ready assistance from his hands. Although he never visited Utah, he sent numerous cuttings of fruit trees, vines, and berries to aid the Mormons in establishing themselves there.

Then the Panic of 1857 caused him considerable loss, he sold his land holdings and moved to Maui (arriving on Christmas day 1879.)

At the time, his oldest son was growing sugar cane there; they contracted with Claus Spreckels for shares, with five hundred acres of land allotted to them and farmed under the name JM Horner & Sons.

“Our crop did well. It exceeded our expectations, in both yield and the price for which it sold. … Our crop yielded two thousand pounds of sugar more per acre than the land cultivated by the plantation, which fact fired its manager with jealousy”.

They “left Mr. Spreckels and contracted with the owners of the Pacific Sugar Mill Co. to do one-half of the cultivation for their mill … Here we made considerable sugar, increasing the yield on our half of the plantation from five hundred tons per year to two thousand.” (Horner)

They then “rented in the district of Hawaiʻi-Hāmākua, twelve hundred and fifty acres since increased to twenty four hundred of good, wild cane land with a view to starting a new plantation”.

“Not wishing to carry all our eggs in one basket, we established a stock ranch where we raised all the horses and mules required on the plantation, and some for sale. We have over four hundred head of horses and mules on the ranch, and one hundred and twenty on the plantation.”

“The ranch has some three thousand four hundred head of beef and dairy stock, the plantation and neighborhood are supplied with butter and beef from the ranch, and the surplus is disposed of elsewhere.” (Horner)

“Horner, a man of broad vision and accurate foresight, was quick to appreciate the possibilities of the sugar industry and was a big factor in its development.”

“At a meeting of the Hawaiian Sugar Planters’ Association in the early 80’s he declared that Hawaii eventually would produce 600,000 tons of sugar a year. His prediction was ridiculed then, but in 1924 the Territory’s output was more than 700,000 tons.”

Hawaiian planters were heavily interested in a refinery at San Francisco, operated in competition with the then powerful sugar trust dominated by the Havermeyers. Under pressure, the Hawaiian planters decided to dispose of their refinery to the trust.

Horner fought this move at every stage, asserting that Hawaii should refine its own produce and remain independent, and was the last man to transfer his holdings in the California enterprise. (Nellist)

Public duties also called and he served at two sessions as a Noble in the Hawaiian legislature. Horner died at his home on Hawaiʻi in 1907, at the age of 86 years. (Nellist) (Lots of information here from Nellist and Horner autobiography.) The image shows John Meirs Horner.

Cane Trash

When we were kids and went fishing (trolling), I remember the frustrating – and repeated – need to pull in and clean the lines from floating bagasse (cane trash) that entangled at the lures.

It wasn’t a new thing, floating masses of bagasse have littered beaches/shorelines, affected fishers, and impacted marine resources for decades before.  Several attempts to use bagasse rather than dump it (fuel to operate the mill, canec, etc) helped, but it wasn’t until the 1970s that the dumping finally stopped.

Sugar was a canoe crop; the early Polynesian settlers to Hawaiʻi brought sugar cane with them and demonstrated that it could be grown successfully in the islands.

In pre-contact times, sugarcane was not processed as we know sugar today, but was used by chewing the juicy stalks.  Its leaves were used for inside house thatching, or for outside (if pili grass wasn’t available.) The flower stalks of sugar cane were used to make a dart, sometimes used during the Makahiki games. (Canoe Crops)

The first written record of sugarcane in Hawaiʻi came from Captain James Cook, at the time he made initial contact with the Islands.

On January 19, 1778, off Kauai, he notes, “We saw no wood, but what was up in the interior part of the island, except a few trees about the villages; near which, also, we could observe several plantations of plantains and sugar-canes.”  (Cook)

Cook notes that sugar was cultivated, “The potatoe fields, and spots of sugar-canes, or plantains, in the higher grounds, are planted with the same regularity; and always in some determinate figure; generally as a square or oblong”.  (Cook)

Sugarcane, a tall perennial grass, is grown in tropical and semitropical climates. (USDA)  “Sugar cane, described in botany as Saccharum officinarum, is a giant-stemmed perennial grass that grows from eight to twenty-four feet long. … As a rule, sugar cane consists of about eighty-eight per cent of juice and twelve per cent of fiber”. (Rolph)

The first reported processing of sugar was noted … “in 1802 sugar was first made at these islands, by a native of China, on the island of Lanai.  He came here in one of the vessels trading for sandal wood, and brought a stone mill, and boilers, and after grinding off one small crop and making it into sugar, went back the next year with his fixtures, to China.”  (Torbert; Polynesian, January 31, 1852)

As production grew, the early sugar ventures were either Hawaiian-owned or regulated by Hawaiian rulers.  In most instances, the Hawaiian-owned sugar processing was managed by either Chinese sugar boilers or American shopkeepers in rural districts.  (MacLennan)  Although sugar cane had grown in Hawaiʻi for many centuries, its commercial cultivation for the production of sugar did not occur until 1825.

In that year, John Wilkinson and Governor Boki started a plantation in upper Mānoa Valley. Within six months they had seven acres of cane growing, and by the time Wilkinson died, in September 1826, they had actually manufactured some sugar. The sugar mill was later converted into a distillery for rum, prompting Kaʻahumanu to have the cane fields destroyed around 1829.  (Schmitt)

Shortly thereafter, King Kamehameha III, seeking to encourage commercial cultivation of sugar by native Hawaiians offered the “acre system,” giving “out small lots of land, from one to two acres, to individuals for the cultivation of cane.”

“When the cane is ripe, the King finds all the apparatus for manufacturing & when manufactured takes the half. Of his half one fifth is regarded as the tax due to the aupuni (government) & the remaining four fifths is his compensation for the manufacture. These cane cultivators are released from all other demands of every description on the part of chiefs.”  (Armstrong (1839;) MacLennan)

About this time, the initial signs of commercial sugar are found on Maui, in Wailuku.  In 1840, the King ordered an iron mill from the US, and it was erected by August.  Hung & Co in 1841 advertised the sale of sugar and sugar syrup from its 150-acre plantation in Wailuku. More than likely, this was sugar from the King’s Mill.  (MacLennan)

Early plantations were small and didn’t fare too well.  Soon, most would come to realize that “sugar farming and sugar milling were essentially great-scale operations.”  (Garvin)

Then, the King sought to expand sugar cultivation and production, as well as expand other agricultural ventures to support commercial agriculture in the Islands.  In a speech to the Legislature in 1847, the King notes:

“I recommend to your most serious consideration, to devise means to promote the agriculture of the islands, and profitable industry among all classes of their inhabitants. It is my wish that my subjects should possess lands upon a secure title; enabling them to live in abundance and comfort, and to bring up their children free from the vices that prevail in the seaports.”

“What my native subjects are greatly in want of, to become farmers, is capital with which to buy cattle, fence in the land and cultivate it properly. I recommend you to consider the best means of inducing foreigners to furnish capital for carrying on agricultural operations, that thus the exports of the country may be increased …”  (King Kamehameha III Speech to the Legislature, April 28, 1847; Archives)

A few things helped kick-start this vision – following finding gold in 1848, the California gold rush stimulated a small boom in commercial agriculture for the Islands – particularly in potatoes and sugar.  However, by the end of the 1850s, the boomlet became a depression (California started to supply its own needs.)

The American Civil War virtually shut down Louisiana sugar production during the 1860s.  Hawaiian-grown sugar soon replaced much of this southern sugar through the duration of the conflict.

By the end of the war, over thirty extremely prosperous plantations were in operation and expanded to new levels previously unheard of before the war’s commencement. 

Hawaiʻi’s industrial plantations began to emerge at this time (1860s;) they were further fueled by the Treaty of Reciprocity – 1875 between the United States and the Kingdom of Hawai‘i eliminated the major trade barrier to Hawai‘i’s closest and major market.

A century after Captain James Cook’s arrival in Hawaiʻi, sugar plantations started to dominate the landscape.  Hawai‘i’s economy turned toward sugar in the decades between 1860 and 1880; these twenty years were pivotal in building the plantation system. 

The industry came to maturity by the turn of the century; the industry peaked in the 1930s. Hawaiʻi’s sugar plantations employed more than 50,000 workers and produced more than 1-million tons of sugar a year; over 254,500-acres were planted in sugar.

Sugarcane is crushed in the mill to extract and process the sugar.  Several waste products are produced by the sugar industry – one was bagasse (the fibrous residue that remains after sugarcane stalks are crushed to extract the juice), and the mills would flume it out of the mill and simply dump it in the ocean.

Later, some of the bagasse was made into fiber board.  In 1929, Hawaiian Cellulose Ltd, a subsidiary of the Waiākea Mill Company applied for a patent for the manufacture of it.  (County of Hawai‘i)  They made ‘canec.’

Canec was originally the brand name for pressed fiber board made by Hawaiian Cane Products, Ltd, but it became commonly used to refer to all pressed board of this type.

Also, later, “After passing through the last mill, as much cane pulp (bagasse) as needed is fed into the mill fireroom for use as fuel.”  (EPA)  The bagasse was pelletized and fueled the boiler.

In 1971, ecological studies of coral communities along the Hamakua Coast of the island of Hawaii resulted in the instigation of a number of Environmental Protection Agency restrictions regarding ocean disposal by sugar mills.

These included, among other things, the elimination of bagasse discharge into the ocean and significant reductions in total suspended solid (TSS). Compliance with EPA standards was achieved in 1979. (Grigg)

Mats of bagasse no longer clogged and smothered rocky bottom habitats. Also mats of bagasse on the ocean surface no longer fouled fishing boats and fishing gear. (Grigg)
