<p>The way and arrangement for manufacturing alcohol, specially for motor fuel, is based upon the use of unsorted cellulose bearing waste as starting material. Household waste consists largely of packages of plastic laminated cardboard and other products of mixed materials, where the cellulose material cannot be extracted through assorting. According to the invention such unsorted cellulose bearing mixture, specially household waste is decomposed (1), cleared (2) of iron, other metals, glass etc. and screened. Thereafter the cellulose and other polysaccarides are hydrolysed (9) to simpler sugar sorts which after being pH-adjusted (10) are fermented (11) to alcohol. The mash residuum is separated (12) and compressed (14) to briquettes. From the purified solution the alcohol is distilled (13). It can be used as motor fuel.</p> |
