FUEL FROM RUBBISH. WASTE PAPER AND OLD HOPSA remarkably brilliant piece of chemical work has been accomplished by two British chemists, Mr H. Langwell and Mr H. Lloyd Hind, who have discovered a new microbe, oy the aegney of which some 12,0*00 tons of waste material can be dealt, with annually to produce about half a million gallons of alcohol suitable for motor spirit and acetic acid. The raw material is the waste hops which at the present time brewers have to pay to have carted aw_ay, but the real value pf the microbe process lies in the fact that it enables alcohol to be produced from sulphide pulp, and thus from waste paper. The microbe is stated to be a rodshaped bacillus, and it, possesses the excellent and convenient property of developing so much heat in its growth that, other organisms which might, interfere with the alcoholic fermentation are automatically killed. Apart from the motor spirit yielded, some 15,000 cubic feet of gas suitable for internal combustion engines are evolved in the treatment of a ton of waste material. Barley, potatoes, or mangolds, if fermented and distilled,, would supply fuel alcohol. In Canada alone there is sufficient sulphite liquor run as waste from the paper pulp mills to produce more than 5X100,000 gallons of spirit a year. Fifty million gallons could be obtained annually from the sawdust and waste wood of British Columbia.
