SOLID WASTE PROCESSING WITH PYROLYSIS OF CELLULOSIC WASTE
Waste, such as municipal solid waste (MSF), is separated into a wet fraction and refuse derived fuel (RDF). For example, the waste may be separated in a press. The wet fraction is treated in an anaerobic digester. The RDF is further separated into a cellulosic fraction and a non-cellulosic fraction. The cellulosic fraction is treated by pyrolysis and produces a pyrolysis liquid. The pyrolysis liquid is added to the anaerobic digester.
THERMOCHEMICAL REACTOR AND PROCESS
A reactor is described which is useful for the generation of hydrocarbon products by thermochemical treatment. The reactor comprises a feeding means for the addition of feedstock material to the reactor; an outlet for the extraction of hydrocarbon products from the reactor; a devolatilization zone; and a cracking zone; wherein the devolatilization zone comprises a first gas distribution base plate for the generation of a fluidised bed of material in the devolatilization zone, the cracking zone comprises a second gas distribution base plate for the generation of a fluidised bed of material in the cracking zone, and the devolatilization zone is in fluid communication with the cracking zone through a plurality of apertures within the second gas distribution base plate permitting the passage of gas from the devolatilization zone into the cracking zone. Processes of producing hydrocarbon products by thermochemical treatment are also described. The hydrocarbon products may be useful as drop-in fuel products and/or chemical feedstock.

Processes are also described to make and use the biomedia compositions.
Carbon capture system
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.
