Circular economy

Today we live in a linear, take-make-waste economy. Products are used and thrown away, denying us access to still valuable and often scarce natural resources, and further contributing to pollution. In a circular economy, however, the entire product lifecycle is designed to eliminate waste and pollution. When one product is no longer viable, its materials and components are put back into use in other ways. Everything is recirculated, leading to the regeneration seen in natural systems.

Thanks to our unique understanding of separation and thermal technologies, Alfa Laval has led the way in the development of new solutions to advance the circular economy. Today we can help you improve resource efficiency and the reduction, reuse, and recycling of waste to optimize your production processes for more reliable and sustainable performance. Together, we can accelerate the transition to a circular economy for bio-based chemicals, bioplastics, biofuels, municipal solid waste (MSW), zero liquid discharge (ZLD), recycling of plastics, textiles and more.

Defining the circular economy

The circular economy, as defined by the Ellen MacArthur foundation, is based on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems.

In other words, nothing go to waste and all our natural resources are used in the most efficient way, again and again. Products are produced using renewable energy. Within production processes, water, chemicals and materials are reused, reduced and recycled. By-products are extracted to enter other circular systems. The product is then used for as long as possible. If broken, a product is repaired instead of thrown away. At the end of a product’s lifecycle, its constituent components are recycled, to be put back in to production again, completing the circle. Biological material that is not recycled instead degrades, renewed with sunlight, CO2 and nutrients to enable the growth of new natural resources.

This will, of course, be a huge change for industry, but a necessary one. Is your operation ready to transition to a circular business model? If so, contact us today to learn about the many ways our solutions can help you achieve your goals.

A pioneering collaboration for sustainable recycling

Alfa Laval and Stena Recycling have teamed up in the development of a groundbreaking business model to enable efficient recycling of heat exchangers. The partnership between the two leaders in their respective fields could enable as much as 100% regeneration of valuable metals found in Alfa Laval’s products. Additionally, it will contribute to the replacement of older heat exchanger technologies with more modern, energy efficient designs that help to reduce global carbon emissions.

“This is an important step towards a more circular and sustainable approach… This initiative is a win-win, to the benefit of our customers as well as to society,” says Susanne Pahlén Åklundh, President of the Energy Division.

“The collaboration with Alfa Laval shows once again what effective circular solutions we can create when we work together," says Fredrik Pettersson, Managing Director of Stena Recycling Sweden.

Resource efficiency

What does it really mean to use resources more efficiently? Ultimately, it’s about increasing yield by, of course, getting the most out of every raw material, but also ensuring that absolutely nothing goes to waste.

When done right, resource efficiency not only improves the sustainability of your operation. It can also be a smart way to cut costs and boost profitability. From green and bio-based chemicals to natural refrigerants, Alfa Laval has the diversity of solutions and expertise to help you improve the circularity of your resource consumption. Learn how we can support your industry today.

Reuse, reduce & recycle

Most industrial processes today consume a great deal of natural resources and produce significant amounts of waste as a result. With the right technology, however, it has become increasingly possible to minimize waste output and thereby shrink both your environmental footprint and operational costs.

Alfa Laval has extensive experience supporting customers with on-site treatment and recovery solutions that enable improved management of your waste and water streams. Our highly efficient separation and water management solutions can help you reduce, reuse and recycle waste in all new ways.

Product lifetime

Ensuring sustainability in the circular economy also means optimizing and maximizing the lifetime performance of each product.

At Alfa Laval, this is a major part of how we consider the designs of our equipment and the materials we use. We work with customers to ensure our products are operated in the optimal way to ensure long-lasting, efficient performance. Our comprehensive service portfolio ensures every Alfa Laval customer has the right support to get the best lifetime operation from their equipment. In some cases, we can even advise on how the product can be reused and recycled at the end of its life.

Recycling

In the circular economy, the last product lifecycle phase is recycling. This enables us to take advantage of the components and natural resources within the product, returning them to production. Today, emerging processes are creating new possibilities for the commercialization of recycling processes for plastics, textiles, batteries, municipal solid waste (MSW) and more.
