适应地球环境新常态 专家提出生态环保新思路
地球环境新常态 生态环保新思路 人口增长 气候变化
2017/2/13
一个国际专家小组在新一期美国《科学》杂志上发表报告指出，面对人口增长和气候变化，环保主义者应该利用新形成的生态系统，注重维护生态系统结构与功能的多样化，增进生态系统的适应能力，而不应总是试图让生态系统保持过去的状态。专家指出，地球面貌已经发生极大变化。人类活动改变了地球上47%没有冰雪覆盖的地方，形成了新的生态系统。这种新常态未来还会出现更多。新生态系统汇集了工业社会前并不存在的物种或系统，包括农...

乌克兰专家研发出有机废物回收新技术
乌克兰专家 有机废物回收
2016/7/6
乌克兰每年工业生产废物可达千万吨，亟需对其合理利用。为此，乌克兰国家科学院生物有机化学和石油化学研究所的专家开发出从工业生产废物中提取有用物质的新技术，即采用从城市污水中提取干物质的专利技术。这种垃圾体的湿度达99％，首先用特殊试剂和特制设置对沉积物脱水，然后干燥，高温气化（约1200-1300?C），快速热解（无氧有机化合物热分解），获得高能气体，进一步燃烧发电。热处理后，除气体外，形成所谓的“...
