The company takes CO2 from any industrial source – a power plant or a refinery, for example – and injects it into concrete, where it is sequestered and turned into a solid.
The start-up of a 10m tonne-per-year refinery in Kunming , south-west China, accounts for about half the anticipated capacity expected to be added in the country this year, swelling an estimated 100m tonnes of existing excess capacity.
At the peak, refineries were paying collectors $3 a gallon for rendered cooking oil, said Ryan Faulkner, general manager of the Virginia Biodiesel Refinery company.
