摘要:

为减轻纺织生产和消费带来的原料消耗压力和环境污染问题,促进生活源废旧纺织品的高值化再利用,从消费者动力、回收成本、技术难题和政策标准4个方面总结回收再利用体系的二大现实难点:一是如何鼓励消费品牌商尽可能地使用更多的再生原料;二是如何实现高值化再生产品的标准化和规模化生产。在此基础上,提出“一溯两消三推动”的体系构建思路,即“逆向追溯推动消费力,消费者推动消费品牌,技术推动高值化”的新模式。同时,指出体系构建后的落地建议,以期进一步推动生活源废旧纺织品的高值化回收再利用。

关键词: 生活源废旧纺织品, 回收体系, 再利用, 高值化, 再生原料

Abstract:

Aiming at pressure reduction in raw material scarcity for textile production and consumption, and at alleviating environmental pollution, a high-value recycling system for the municipal textile wastes was proposed based on the problem analysis from four perspectives, i.e. purchasing motivations, recycling costs, technical difficulties and policy issues. Two problems were identified to be the most important, the first one being on how to encourage consumer brands to utilize more recycled materials, the other on how to achieve standardized and large-scale high-value textile wastes re-production. This paper proposes to construct an innovative system, the strategy of which involves the reverse logistics to promote consumption, consumers' purchasing behavior to promote consumer brands, and technology to promote high-value recycling. By providing practical suggestions, this concepts raised in paper would promote further the high-value recycling of textile wastes.

Key words: municipal textile waste, recycling system, re-utilization, high-value, recycled material
