LIHU’E —Representatives of three trash disposal companies bidding for the
county solid waste contract reviewed their proposals at a public meeting
Monday. All three proposed various recycling technologies.
representatives from two other companies bidding for the contract proposed
waste to energy facilities to manage the county’s solid waste.
Conporec, HUWS Corporation and Canada Composting have proposed recycling
facilities while Seggersbetter Tecnology and Gay & Robinson are proposing
waste to energy management facilities,
Jeffrey H. Heath, Groupe Conporec
program manager, said that his company uses a recycling process that will
divert 75 percent of Kaua’i’s municipal solid waste from the Kekaha landfill
and produce a high grade commercial compost product for resale.
said the company is committed to environmental sensitivity and worker safety
and as such the entire process takes place in a closed looped facility and is
Conporec’s process begins with a sorting stage that removes all
the non-organic material such as metals and plastics from the waste stream. The
remaining material goes into a patented bio-reactor that process the organic
material into a agricultural organic compost end product.
proposing to build the recycling plant on 10-15 acres of land in the Puhi-Lihue
area and will take two and a half to three years to be fully operational
employing 15 full-time employees.
HUWS (Herhof Urban Waste Solution) has
developed a patented method for recycling that is called dry-stabilate
Precisely crushed solid waste is hermetically sealed in Herhof
-boxes where the water content is reduced using a biological degradation
process. After processing the company separates the reduced waste into various
components; metals for recycling, organics for composting, aggregate for road
fill and pelletised “green” fuel that can be sold to a electrical power
producer for energy generation.
Marie-Claude Boucher, HUWS president, said
that community input will determine where their plant is located. The plant
would require two acres of land, would take one and a half years to build and
employ nine workers. The HUWS process diverts 92 percent of waste from the
HUWS can also build a co-generation component that produces
electricity for sale to the local power company. Boucher said one ton of
stabilate equals 2 barrels of diesel oil.
Canada Composting is proposing
to build what the company calls a fully integrated recovery plant that will
take trash and produce organic compost, liquid fertilizer, power itself and
have 1.2KWH of power left over for sale to the local electric company.
process begins with a materials recovery stage where plastics, metal, and paper
are removed from the waste stream and recycled.
The remaining organics
goes through a BTA process of metabolic digestion where the trash breakdown
produces a gas to power the recycling plant and produce 16,000 tons of compost
Canada Composting has three potential locations the first being
adjacent to the Koloa Mill, second at the site of Kauai Nursery and
Landscaping, a partner in the project, and behind the Lihue Refuse
The proposed plant will require five acres of land and 16
full-time employees. Kevin Matthews, CCI president, said their process will
divert 72 percent of solid waste from the landfill and can be constructed to
blend with the local architecture. He showed an example of a plant in Germany
that resembled a farm.
This meeting completed the public presentations of
the five companies who were selected to bid on the 20 year County solid waste
Jean Camp, executive assistant to Mayor Maryanne
Kusaka who is facilitating the bid process, said the public meetings produced a
lot of good feedback from the community and the local business.

She said the county hopes to award a contract in August.
