The environmental-friendliness of paper diaper and garbage disposer was examined.1) The prooduction of paper diaper is increasing linearly upto 7.7 billion sheets in 1996, especially diaper for adults is increasing more than for babies.2) The weight of paper diaper after use is 150-180g, and the weight of excreta is 101-131g.3) Textile diaper is cheaper than paper diaper if the wages of mother are neglected. It means that textile diiaper seems to be partly used by the economical reason.4) The discharge of pullutant load from textile diaper washing for a baby of 0.8-1.8 years old was TN 3.4g/cap/d, TP 0.218g/cap/d including feces.5) The environmental load of paper diaper was larger for material consumption and the amount of wastes and less for energy and water consumption, pollutant load to water and air pollution comparing with textile diaper.1) The use of disposer is forbidden or guided to be self-controled by the administration, and the production of disposer is hardly found domestically.2) Electric power consumption is 0.02kwh/cap/day.3) The pollutant load of garbage was amount 302g, CODcr 51g, N 1.3g, P 0.15g including orange peerings and 200,37,0.9,0.12g/capita/day excluding them respectively.4) The system introducing disposer is more expensive by 20% and environmental load of air pollution is lower for air pollution and higher for water pollution, comparing with the present system.As huge amount of data collection is necessary to complete LCA,the reliability of the value presented should be cheked carefully. The LCA for a certain product might be indipensable to the help of organized power and the corperation of enterprizes.The related matter to the thermal recycle of RDF and power generation by solid waste incineration should be further studied.

对纸尿裤和垃圾处理器的环保性进行了研究。1）纸尿裤的产量呈线性增长，1996年达77亿张，特别是成人纸尿裤的产量增长超过婴儿纸尿裤。2）纸尿裤使用后的重量为150- 180克，排泄物的重量为101- 131克。3）如果不考虑母亲的工资，纺织尿布比纸尿布便宜。这意味着纺织尿布的使用似乎部分是出于经济原因。4）0.8-1.8岁婴儿纺织尿布洗涤的污染物负荷排放量为TN 3.4g/人/天，TP 0.218g/人/天（包括粪便）。5）纸尿布的环境负荷在材料消耗和废物量方面较大，能源和水消耗较少，1）处理器的使用被政府禁止或引导自行控制，国内几乎没有生产; 2）耗电量为0.02kwh/人/天; 3）垃圾污染负荷量为302 g，CODcr 51 g，N 1.3g，P 0.15 g（含橙子豌豆）和200、37、0.9、0.12 g/人/天（不含它们）。4）与现有系统相比，引入处理器的系统成本高20%，空气污染的环境负荷较低，水污染的环境负荷较高。所提供的价值的可靠性应仔细检查。某一产品的生命周期评价可能依赖于有组织的力量和企业的合作，RDF的热回收和固体废物焚烧发电的相关问题有待进一步研究。
