Sir, — It seems that Tony Kunowski (April 8) has not considered the production of liquid fuel from wood. This process is technically and economically feasible for it could utilise waste from forest industries and harvestable forest residues as well as wood grown for the purpose. An annual harvest of 25,000 to 35,000 hectares of Pinus radiata would satisfy all New Zealand's present liquid fuel requirements. Profitable production of fuel alcohol, selling at 21 cents a litre is possible from a plant operating on 500 oven-dry tonnes a day. This corresponds to the quantity of waste wood now burnt at the large North Island pulp mills. The pulp and paper industry could produce the large quantities of power it requires, and could also produce more than $3B million in export earnings as it has in the past, as the value of output is increasing rapidly, at a rate greater than New Zealand industry’s average. The future of liquid fuel is greater than that of electric trains. — Yours, etc..
JEFFREY SOLE. April 8, 1978.
