During construction a lot of this waste spends in a landfill leaching toxic chemicals into the surrounding environment. Results of a recent questionnaire demonstrate that although 95.71% of construction projects indicate that construction waste is problematic, only 57.14% of those companies collect any relevant data.

Some methods use the hybrids of these two methods. The anaerobic digestion of the organic fraction of solid waste is more environmentally effective than landfill, or incineration. [ 50 ] The intention of biological processing in waste management is to control and accelerate the natural process of decomposition of organic matter.
A waste converter is a machine used for the treatment and recycling of solid and liquid refuse material. A converter is a self-contained system capable of performing the following functions: pasteurization of organic waste; sterilization of pathogenic or biohazard waste; grinding and pulverization of refuse into unrecognizable output; trash compaction; dehydration.
The human sewage and the process waste from the manufacturing industries are the two major sources of the waste water. In Thailand, the total volume of the wastewater from industries is much greater than that of the domestic sewage. [2] As a result, an effective method is needed.
In the UK some of these are sometimes termed advanced waste treatment technologies. Biodrying; Gasification. Plasma gasification: Gasification assisted by plasma torches; Hydrothermal carbonization; Hydrothermal liquefaction; Mechanical biological treatment (sorting into selected fractions) Refuse-derived fuel; Mechanical heat treatment; Molten ...
Process flow chart. The terms mechanical biological treatment or mechanical biological pre-treatment relate to a group of solid waste treatment systems.These systems enable the recovery of materials contained within the mixed waste and facilitate the stabilisation of the biodegradable component of the material.
SOIL's two composting waste treatment facilities currently transform over 20,000 gallons (75,708 liters) of human excreta into organic, agricultural-grade compost every month. [67] The compost produced at these facilities is sold to farmers, organizations, businesses, and institutions around the country to help finance SOIL's waste treatment ...
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes.
