Aged waste is the product of the natural evolution of waste over a longer period of time after it has been landfilled. After years of microbial decomposition and fermentation, it is usually high in moisture and low in organic matter. The largest portion of aged waste is high calorific value combustible material, which can be pre-crushed to the proper size to make high quality "alternative fuels (SRF/RDF)", which can increase the benefits of power generation for enterprises.
