Abstract
Abstract In transit refuse recovery and incineration system for processing refuse as it is collected including bag-ripping, sorting, shredding, pre-heating and pre-volatilization, classifying, incineration, gas clean-up, and bins for re-cyclable items and ash. Pre-heating and pre-volatilization, in conjunction with air classifying prior to incineration, leads to low air-flow usage, compactness and mobility, dioxin reduction, and high gas clean-up efficiency.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A mobile unit for processing refuse as it is collected comprising an outer casing, means for bag ripping followed by means for sorting high density matter from low density matter followed by means for shredding followed by means for pre-heating and classifying the matter into a light fraction and a heavy fraction followed by means for separating the light fraction from the gas stream followed by means for incinerating the light fraction followed by means for cleaning the combustion gases, means for collecting the resource recovery items and ash.
Claim 2
Dependent Claim
89 words
A mobile unit for processing refuse as it is collected comprising an outer casing, means for bag ripping followed by means for sorting high density matter from low density matter followed by means for shredding followed by means for pre-heating and classifying the matter into a light fraction and a heavy fraction followed by means for separating the light fraction from the gas stream followed by means for incinerating the light fraction followed by means for cleaning the combustion gases, means for collecting the resource recovery items and ash.
Claim 3
Dependent Claim
16 words
A mobile unit according to claim 1 in which the outer casing contains sound absorbing means.
Claim 4
Dependent Claim
24 words
A mobile unit according to claim 1 in which the means for sorting consists of a trommel or rotating screen inclined to the horizontal.
Claim 5
Dependent Claim
18 words
A mobile unit according to claim 1 in which the means for sorting consists of a magnetic separator.
Claim 6
Dependent Claim
19 words
