回收和废物管理

回收倡议针对的是各种废料,包括电池、建筑垃圾和生物垃圾等日常用品。要重新利用这些不同的材料,通常需要将其粉碎和均质化,使其形成新的形状和新的物品。例如,用废旧瓶子中的碎玻璃颗粒可以制作新的瓶子或艺术品。另一个想法是将纺织品和皮革粉碎,然后用这些粉末制作新的家具覆盖物。尽管使用的是粉碎材料,但仍需要进行质量控制,以确保不会再使用有害物质,例如建筑垃圾中的石棉或电子垃圾中的有毒成分;

回收利用的优势

回收利用各种材料是指回收和再利用这些材料,而不是填埋或焚烧废物。这些材料经过加工后重新用于新的项目,通过减少对新原材料的需求,保护了用于木材生产的森林和用于皮革生产的兽皮等自然资源。这一过程还能降低分解和焚烧过程中的温室气体排放,减少与生产新材料相关的能源消耗,从而减少对环境的影响。此外,回收还能降低工艺的总体成本。例如,与从原材料中提取铝相比,回收铝可节省高达 90% 的能源。获取原材料所需的矿山数量减少,从而减少了对环境的污染。通过再利用电子废物和确保质量控制,减少了有害物质对环境的污染。回收利用还能节约用水,因为回收利用过程比使用原材料所需的水更少。例如,每吨再生纸可以节约数千升水、数千度电和十几棵树。回收利用污水污泥、食物、庭院边角料和农业残留物等有机废物,可将其转化为堆肥和沼气等宝贵资源。这一过程在废物管理战略中至关重要,它可以将有机废物从垃圾填埋场转移出来,因为垃圾填埋场中的有机废物会厌氧分解并产生甲烷--一种强烈的温室气体。现在,随着技术的进步,可以提取以前在经济上无法回收的有价值矿物,包括微量金属,如金、银、铜和稀土元素。

通过电子废弃物的再利用和质量控制,减少了有害物质对环境的污染。回收过程比使用原材料更节水,例如每吨再生纸可节约数千升水、数千千瓦时电力及十余棵树木。有机废弃物(如污水污泥、食物残渣、庭院修剪物及农业残余)经回收后可转化为堆肥和沼气等宝贵资源。这一过程在废物管理策略中至关重要,它能将有机废物从垃圾填埋场转移——这些废物在填埋场会进行厌氧分解并产生强效温室气体甲烷。技术进步如今使我们能够提取先前因经济性不足而无法回收的宝贵矿物,包括金、银、铜等微量金属以及稀土元素。

Innovative designs from recycled food waste

Innovative designs from recycled food waste

Food waste is a significant global issue that impacts the environment, economy, and society. Every year, millions of tons of food are wasted, contributing to greenhouse gas emissions, resource depletion, and economic losses. Food waste occurs at various stages of the supply chain, including production, processing, distribution, and consumption. The environmental impact of food waste is substantial, as it leads to the unnecessary use of water, energy, and land resources, while also generating methane emissions from decomposing organic matter in landfills.
