来源：http://www.sztensun.com/ 日期：2024-11-16

　　塑料袋的回收再利用可以通过以下几种方法实现：

　　The recycling and reuse of plastic bags can be achieved through the following methods:

　　能量回收 ：

　　Energy Recovery:

　　对废旧塑料袋进行燃烧，利用其产生的热量进行能量回收。

　　Burning waste plastic bags and utilizing the heat generated for energy recovery.

　　热裂解 ：

　　Thermal cracking:

　　将挑选过的废旧塑料袋经过热裂解，制得燃烧料油和燃料气。

　　The selected waste plastic bags are subjected to thermal cracking to produce combustion oil and fuel gas.

　　回收化工原料 ：

　　Recycling chemical raw materials:

　　通过化学分解废旧塑料，将其变成化工原料，如聚酯氨等，再通过水解获得合成时的原料单体。

　　By chemically decomposing waste plastics and turning them into chemical raw materials such as polyester ammonia, the raw material monomers for synthesis are obtained through hydrolysis.

　　熔融再生 ：

　　Melting regeneration:

　　将废旧塑料袋重新加热塑化，分为两类：

　　Re heat and plasticize waste plastic bags, divided into two categories:

　　树脂厂的边角料，可以制成比较好的塑料制品。

　　The scraps from resin factories can be used to make better plastic products.

　　使用后混杂的塑料制品，只能重新制造性能较差的塑料制品。

　　Mixed plastic products after use can only be remanufactured into plastic products with poor performance.

　　回收利用 ：

　　recycling:

　　收集塑料袋并送到回收站或卖给回收厂家，加工成塑料袋、垃圾袋、鞋盒等。

　　Collect plastic bags and send them to recycling stations or sell them to recycling manufacturers for processing into plastic bags, garbage bags, shoe boxes, etc.

　　重复使用 ：

　　Reuse:

　　对于干净无污染的塑料袋，可以多次重复使用，节约资源并减少塑料垃圾产生。

　　For clean and pollution-free plastic bags, they can be reused multiple times to save resources and reduce plastic waste generation.

　　垃圾分类 ：

　　refuse classification:

　　将难以再生的塑料袋作为垃圾分类处理，方便垃圾处理并保护垃圾桶。

　　Classify and dispose of difficult to regenerate plastic bags as garbage to facilitate waste disposal and protect the garbage bin.

　　作为保鲜袋和防尘工具 ：

　　As a fresh-keeping bag and dust-proof tool:

　　将塑料袋用作保鲜袋或防尘工具，延长其使用寿命。

　　Use plastic bags as fresh-keeping bags or dust-proof tools to extend their service life.

　　物理回收 ：

　　Physical recycling:

　　通过粉碎、干燥、造粒、切粒等步骤，将塑料袋转化为新的塑料制品原料。

　　Through steps such as crushing, drying, granulation, and cutting, plastic bags are transformed into new raw materials for plastic products.

　　化学回收 ：

　　Chemical recycling:

　　包括气化、碳捕获和利用焚烧（CCU）、热解、热裂解、溶剂解和酶解等方法，将塑料分解成单体或其他化学原料。

　　This includes methods such as gasification, carbon capture, and incineration (CCU), pyrolysis, thermal cracking, solvent hydrolysis, and enzymatic hydrolysis to decompose plastics into monomers or other chemical raw materials.

　　建议

　　proposal

　　为了更有效地回收再利用塑料袋，建议采取以下措施：

　　To more effectively recycle and reuse plastic bags, it is recommended to take the following measures:

　　提高公众对塑料袋回收再利用的认识和参与度。

　　Raise public awareness and participation in the recycling and reuse of plastic bags.

　　建立健全的塑料袋回收体系，包括收集、分类、处理和再利用的完整流程。

　　Establish a sound plastic bag recycling system, including a complete process of collection, classification, processing, and reuse.

　　研发和推广更的回收技术和设备，降低回收成本，提高再生塑料的质量和利用率。

　　Develop and promote more efficient recycling technologies and equipment, reduce recycling costs, and improve the quality and utilization of recycled plastics.

　　政策和法规上应鼓励和支持塑料袋的回收和再利用，限制一次性塑料袋的使用，促进塑料循环经济的发展。

　　Policies and regulations should encourage and support the recycling and reuse of plastic bags, restrict the use of disposable plastic bags, and promote the development of a plastic circular economy.
