Recycling
在循环经济中，回收利用是产品生命周期的最后阶段，即产品无法再利用、保养或维修的阶段。回收利用使我们能够利用产品中的成分和自然资源，使其重新投入生产。然而，如今只有一小部分材料被回收利用，大部分被送往焚烧或垃圾填埋场。幸运的是，新兴工艺正在为塑料、纺织品、电池、城市固体废物（MSW）等的商业化回收创造新的可能性。
阿法拉伐可以为您提供帮助，为您回收流程中的净化和浓缩步骤提供高效的分离和水管理解决方案。这些成熟稳健的技术有助于减少用水量和不可回收废物的数量。对于热解和气化等工艺中的冷却任务，我们还提供各种传热解决方案。请继续阅读，了解我们如何帮助您将今天的废物转化为明天的价值。
What a waste if we do not recycle it!
Using recycled materials instead of raw materials is an efficient way of both conserving natural resources and preventing pollution. To manufacture materials the second time around is much cleaner and less energy intensive than using raw materials. There is an urgency to accelerate recycling technologies to defossilize the materials industries, and to preserve the valuable raw materials fundamental to our consumables. Today, more than 90 countries have set Net Zero targets with regards to greenhouse gas emissions. The targets put a very clear focus on developing new technology. Circular economy will play an important role in achieving them.
Plastic and derivates recycling
There are various recycling technologies. Key plastic recycling technologies include:
Mechanical recycling
The most common and widely used method for recycling plastic waste. It utilizes mechanical operations, such as sorting, shredding, and melting, to transform the waste into reusable materials, which primarily affect the physical form and size of the plastic waste. In a mechanical recycling process, the chemical structure of the plastic polymer remains intact, with no significant alterations to its chemical composition.
Advanced chemical recycling
Advanced chemical recycling is usually based on either pyrolysis, solvolysis or enzymolysis. It involves breaking down plastic waste into its chemical components or converting it into other valuable products.
Chemical recycling by solvents (Solvolysis)
A process that breaks down polymers into their individual monomers, enabling them to be polymerized to new chemical products. This technology can handle a broader range of plastic types, including complex and contaminated plastics that are difficult to recycle through mechanical means.
Bio-chemical recycling (Enzymolysis)
Biological recycling, also known as biodegradation or composting, involves the use of microorganisms to break down certain types of plastics into organic matter. This method is typically suitable for biodegradable plastics and can be utilized in specific composting facilities.
Thermo-chemical recycling (Pyrolysis)
A thermal decomposition process that converts plastic waste into fuel, such as oil or gas, in the absence of oxygen. It involves heating the plastic at high temperatures, breaking it down into its basic components.
Ash recycling
What is often considered waste today can become a valuable raw material in the future. For example, ash from incineration plants often contain high levels of salt that can be extracted and purified.
Sludge can be used as a raw material for concrete. Valuable metals that were previously too difficult to recover can be concentrated from diluted streams. Wastewater can be turned into fertilizer products. And these are just a few examples of the countless ways to use resources more efficiently.
With our unique solutions for heat transfer and separation, Alfa Laval can increase the performance of virtually any type of recycling plant or operation. We help you boost the production of your plant, taking care of valuable waste and completing the cycle.
Transforming waste into resource: Pyrolysis and the future of circular chemicals
By 2050, recycled carbon will play a major role in chemical production. Pyrolysis is key to converting waste like plastics and tires into valuable materials. Alfa Laval’s technologies optimize this process by improving efficiency, product quality, and environmental compliance. With deep expertise, Alfa Laval supports the shift toward circular carbon and a defossilized future.
