Recycling
在循環經濟中，回收利用是產品生命周期的最后階段，即產品無法再利用、保養或維修的階段。回收利用使我們能夠利用產品中的成分和自然資源，使其重新投入生產。然而，如今只有一小部分材料被回收利用，大部分被送往焚燒或垃圾填埋場。幸運的是，新興工藝正在為塑料、紡織品、電池、城市固體廢物（MSW）等的商業化回收創造新的可能性。
阿法拉伐可以為您提供幫助，為您回收流程中的凈化和濃縮步驟提供高效的分離和水管理解決方案。這些成熟穩健的技術有助于減少用水量和不可回收廢物的數量。對于熱解和氣化等工藝中的冷卻任務，我們還提供各種傳熱解決方案。請繼續閱讀，了解我們如何幫助您將今天的廢物轉化為明天的價值。
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.
