对芬兰7个硫酸盐纸浆厂(代表着不同的技术和厂龄)采集的生产数据进行了有关技术改进与保护环境二者关系的研究。研究发现,支撑技术(supporting technology,如废物处理作业)和核心技术(如液体处理)对于减轻硫酸盐纸浆厂的环境污染负荷是同样重要的。研究结果表明,硫酸盐法制浆的技术改进可改善环境绩效。
A study of the relationship between technological improvements and the protection of the environment was conducted on production data collected from seven sulfate pulp mills in Finland (representing different technologies and plant age). Research has found that supporting technologies such as waste management and core technologies such as liquid handling are equally important for reducing the environmental pollution load on sulfate pulp mills. The results show that technological improvements in kraft pulping can improve environmental performance.
