The continuous process of the present invention is intended to obtain dry biomass from two treatment steps by drying organic waste. The waste previously sieved and crushed waste are dumped into a first dryer, inside of which temperatures are between 280? C. and 300? C. at the inlet thereof and between 90? C. and 100? C. at the outlet, then passing to a conveyor belt where at room temperature a partial cool-down occurs and the waste is dumped into a second dryer inside of which the temperatures are between 180? C. and 200? C. at the inlet and between 75? C. and 85? C. at the exit, completing the process, during which the interior of the dryers is maintained in negative pressure through exhaust flow and the oxygen content is kept between 5 and 7%.

The invention relates to a system for the regenerative thermal oxidation of crude gas, comprising a combustion chamber (29) and a plurality of regenerators (30, 32, 34, 36, 38, 40, 41) which each have a regenerator chamber (42, 44, 46, 48, 50, 52, 54) that communicates with the combustion chamber (29) and contains a heat exchanger (56). The system contains a supply line (58) for feeding crude gas into a crude gas line (60) and has a clean gas line (62) for giving off clean gas, wherein a regenerator chamber (42, 44, 46, 48, 50, 52, 54) of a regenerator (30, 32, 34, 36, 38, 40, 41), in each case independently of the regenerator chambers (42, 44, 46, 48, 50, 52, 54) of the rest of the regenerators (30, 32, 34, 36, 38, 40, 41), can be optionally connected to the crude gas line (60) and separated from the crude gas line (60) via an adjustable crude gas shut-off device (64, 66, 68, 70, 72, 74, 75), as well as optionally connected to the clean gas line (62) and separated from the clean gas line (62) via an adjustable clean gas shut-off device (76, 78, 80, 82, 84, 86, 88). According to the invention, the system comprises a separating device (90) for separating suspended particles in crude gas fed into the crude gas line (60) from the supply line (58).

A system and method to prevent an oxidizer overheating using cold side bypass for a volatile organic compounds (VOCs) treatment system with a series rotor are described, which is mainly used in the organic waste air treatment system. The system is equipped with a thermal oxidizer (to), a first heat exchanger, a second heat exchanger, a third heat exchanger, a first cold-side transporting pipeline, a first adsorption rotor, a second adsorption rotor, and a chimney. A cold-side proportional damper is installed between the first desorption-treated air pipeline and the first cold-side transporting pipeline, or it is installed on the first desorption-treated air pipeline. When the VOCs concentration becomes higher, the cold-side proportional damper can regulate the airflow to adjust the heat-recovery amount or concentration, when treating the organic waste air, it can prevent the thermal oxidizer from being overheated due to high oxidizer temperature, and protect from thermal oxidizer shut-down.

A system and method are provided for converting solid waste into new plastic products by utilizing the plastic from a landfill in new products and the fuel resources in the landfill in the manufacturing process. Biomass waste is combusted by a combustion system to generate residual heat and heated exhaust, and the residual heat and heated exhaust is used to fuel the manufacturing of new plastic products from the recovered plastic waste. Methane gas recovered from the landfill can also be used as a fuel source for heating manufacturing machinery and generating electricity used in the manufacturing processes.
