Under current practices, agricultural or landscaping waste left in a field or forestry waste left in a forest will decay and release greenhouse gases. In addition, forestry waste also poses a high risk for fires. Accordingly, mechanisms are provided to allow efficient conversion under anaerobic conditions of biomass, such as agricultural or forestry waste, into biocarbon product, such as biochar, biocoal, inert carbon and/or activated carbon, using molten salts as a more efficient heat transfer medium than conventional heat. Specifically, biomass is converted into biocarbon product during a supertorrefaction process during which molten salts are pumped under anaerobic conditions from a molten salt reservoir to a batch process cooker that holds the biomass. The salts are washed from the resulting biocarbon product as needed.

A method for processing plastics includes receiving input plastics to be processed. The method further includes driving the input plastics through a reactor chamber having at least two zones each containing heated fluid that is heated to greater temperatures in a subsequent zone such that remaining plastics of the input plastics are exposed to increasingly greater temperatures in each zone of the reactor chamber. The method also includes collecting condensable vapors that flow out of the at least two zones of the reactor chamber. The method further includes condensing the condensable vapors into a liquid condensate. The method also includes removing biochar products from the heated fluid. The method further includes removing contaminants from the reactor chamber.
