§ 44. Mr. ROSBOTHAMasked the Secretary for Mines the tonnage of coal used in the production of by-products for the years 1928, 1929, and 1930?
§ Mr. SHINWELLFigures for 1930 are not yet available. The amount of coal used at gas works and by-product coke ovens was approximately 34,500,000 tons in 1928 and 37,500,000 tons in 1929. In addition, several hundred thousand tons of coal were used in the production of pig iron by processes which include the recovery of by-products. Coal used at low temperature carbonisation plants at gas works is included in the above figures. For plants situated elsewhere no figures are available, but they would not materially affect the total figures I have quoted.
