环境污染和能源不足是当前亟待解决的重大问题。四川省荣县酒厂利用酿酒后的废料制取沼气,既利于保护环境,又得到丰富的能源补给,发展了生产,方便了职工,而且为农业生产提供了优质肥料。荣县酒厂办沼气,一举多得。我们提倡避害趋利,更提倡化害为利。荣县酒厂在这方面动了脑子,下了功夫,他们的做法很有参考价值。 Environmental pollution and lack of energy are major issues to be solved urgently. Rongxian Brewery in Sichuan Province uses biogas after brewing waste to produce biogas, which not only helps to protect the environment but also provides abundant energy supply, develops production, facilitates staff and provides high quality fertilizers for agricultural production. Rongxian wineries do biogas, in one fell swoop. We advocate avoiding profits, but also promote harm to benefit. Rongxian wineries in this area moved their brains, under the effort, their approach is of great reference value.
