Jandakot, Australia

Richgro teams with UK companies for AD plant

Richgro, a compost company based in Jandakot, Western Australia, teamed up with several U.K. companies to open its own anaerobic digestion (AD) facility. The plant uses pumps and mixers from Landia, Cary, North Carolina; gas generators from Edina, Dublin, Ireland; tanks and storage from Kirk Group, Lancashire, England; and flare stacks from Uniflare, Warwickshire, England.

Around 100 tons of commercial food and liquid waste is trucked in each day to the Jandakot plant. The buffer tank acts as a store for the organic matter for the intermittent feeding of the digesters throughout the day. This organic matter is then fed into two 2,500 cubic meter capacity digesters. The feedstock that has passed into the primary digester has its own external heating system which uses the cogenerated surplus heat from the Edina gas engine.

Hønefoss, Norway

Cellunolix ethanol plant to open

Helsinki, Finland-based St1 Nordic Oy’s Norwegian subsidiary, Smart Fuel AS, Oslo, Norway, has signed a letter of intent with Viken Skog SA, Hønefoss, Norway, and its subsidiary Treklyngen Holding AS, Hønefoss, Norway, to construct a Cellunolix ethanol plant in Hønefoss.

St1’s aim is to construct the ethanol plant in the industrial area of Follum in Hønefoss, making use of the existing industrial infrastructure and equipment from the former papermill area. The planned production capacity of the plant is 13 million gallons of advanced cellulosic bioethanol for transportation, using local forest industry residues as feedstock. It is estimated that the project will reach the investment decision stage in 2018 and the plant will be in operation by 2021. St1’s ethanol produced from waste and residues has low carbon dioxide (CO2) balance, generating up to 90 percent lower fossil CO2 emissions than conventional fossil fuels, according to the company.

Can Tho, Vietnam

Vietnam’s first waste-to-energy facility planned

China Everbright International Limited, Hong Kong, China, has won the bid for Vietnam’s Can Tho waste-to-energy project, which will implement technologies for the harmless treatment, reduction and reuse of household waste, and has officially tapped into the solid waste integrated treatment market in Southeast Asia.

Can Tho project will be constructed under build-operate-own (BOO) model, commanding a total investment of approximately $47 million. The project is designed to have a daily household waste processing capacity of 400 tons and will be equipped with a 7.5 megawatt power generator. It is expected to generate approximately 60 million kilowatts per hour of green electricity annually. The core equipment of Can Tho project includes Everbright International’s grate furnace system, gas emission treatment system and leachate treatment system. Its gas emissions will fully comply with the Euro 2010 Standard.
