the invention is an improved system for separating waste products into several components and then providing for total utilization thereof . the systemitized arrangement integrates numerous automatic operations to produce the separation of the components and then provides for automatically directing the separated components to ultimate destinations for total utilization . the system first processes bulk waste products such as garbage , rubbish , and other discarded material and shreds it into small size particles . the shredded waste products are then mixed with sewage sludge received from another source . the mixture is then processed through a controlled sludge composting means . at this point a first benefit is derived by means of hot exhaust air from the controlled sludge composting means being directed to a hot house structure to aid in the growth of food products . following the controlled sludge composting means the resulting compost is separated by screening and the fine material is further cured for direct use in agriculture and gardening type operations . the large particles are further separated by magnetic and ballistic means into various components for specified distribution and uses . concurrently , following the aforementioned shredder , a high velocity air classifier directs the paper , light plastics , and similar waste matter to an incinerating process for generating steam which is used for heating , generating electricity , and other useful purposes . the automatic operations eliminates the need for manual labor for separation and classification operations .
