World news round-up 30 September 2014

Food waste into CNG; EfW plant in Singapore upgraded; Utah call for criminal probe over Stericycle; Mining investment in Chile to reach £65bn; Biomass sector could generate 60% of future needs

Food scrap converted into compressed natural gas

South San Francisco Scavenger Company is teaming up with a facility that processes its waste to convert food scraps into fuel. The new digester at the facility uses dry anaerobic digestion technology to transform the contents of compost bins into compressed natural gas (CNG). The digester will process 11,200 tonnes of compostable materials a year and produce up to 55 diesel gallon equivalents every day of CNG. The process also produces digestate.

EfW plant in Singapore upgraded

Keppel Infrastructure Trust (KIT), through its wholly owned subsidiary Senoko Waste-to-Energy, has agreed a deal with Singapore’s National Environment Agency (NEA) to provide additional incineration capacity to Seneko’s plant, one of the three facilities under KIT’s current portfolio. After completion, the contracted incineration capacity of the facility will increase by 10%. The upgrade will take place between the third quarter of 2015 and Q3 2016. The works mainly include modifications to the plant’s incineration units and the steam-condensate system, and will be scheduled with the planned annual maintenance of each incineration unit.

Biogas plant commissioned in Sweden

A biogas plant, co-owned by Swedish Biogas International and local farmers, has been commissioned in Västerås, Sweden. The digester, which has been functional for some time, did not begin to supply biomethane to Svensk Växtkraft until 22 September following a problem with the upgrader. The facility will treat 80,000 tonnes of manure and 10,000 tonnes of agricultural waste and will produce gas for use by vehicles.


Criminal allegations over Stericycle

The governor of Utah state in the US has urged that a criminal investigationbe imposed on a medical waste incinerator owned by Stericycle in North Salt Lake. The incinerator operators face allegations of air pollution. The criminal investigation comes in addition to separate probes into activities at the plant launched by the state’s Department of Environmental Quality and its Labor Commission.


Biomass could generate 60% of future energy

A report by the International Renewable Energy Agency found that the renewable energy produced from biomass could supply a fifth of world’s energy needs by 2030. Sources ranging from wood to agricultural waste could generate around 60% of renewable energy supply. If the full potential of biomass is realised, according to the report, 40% of this energy could be derived from agricultural residues and waste, with another 30% generated with sustainable forestry products.

European steel sector set to downsize staff

European steel companies will have to reduce staff numbers in an effort to bolster their earnings, reflecting a drop in demand and Asian competition. Steel firms were lagging behind their peers in China, India and South Korea in terms of technology and innovation. Steel demand is anticipated to return to growth in Europe this year, but cheaper steel imports from outside the EU have put pressure on margins.
