从国家经委1988年4月9日在桂林召开的全国散装水泥工作会议上获悉,全国水泥包装用木材浪费量大,包装纸紧缺,要求各地加快发展散装水泥。我国历来习惯于用纸袋包装水泥。专家们以1987年全国水泥总产量1.8亿吨测算,年耗包装纸108万吨,造纸需用木材600万立方米。而散装水泥不仅节约木材,而且每吨节约包装 It was learned from the National Bulk Cement Work Conference held by the State Economic Commission on April 9, 1988 in Guilin that there was a large amount of waste of wood for cement packaging in the country, and there was a shortage of packaging paper, which required the localities to accelerate the development of bulk cement. China has always been accustomed to packing cement with paper bags. Experts estimated that with a total cement production of 180 million tons in 1987, annual consumption of packaging paper was 1.08 million tons, and papermaking required 6 million cubic meters of wood. Bulk cement not only saves wood, but also saves packaging per ton
