Our offering in circularity

Supporting circularity is an important part of our business model. We can impact resource scarcity, waste, emissions and energy consumption in many ways, and the methods are continuously developing.

Our offering in circularity

Circularity does not only mean recycling. It can refer to other things as well, like extended equipment and product lifetime. Our current economy is built around a process of extracting materials from the Earth, making products from them, and ultimately throwing them away as waste – a linear process. Humans are on track to consume three planets worth of resources annually, and modern society will have high expectations of the mining industry to continue delivering the metals required for the global energy transition but at minimal environmental impact.

In a circular economy, no waste is produced in the first place and materials are kept in circulation and use for as long as possible. The circular economy decouples economic activity from the consumption of finite resources and is underpinned by renewable energy and materials. Ultimately, it is a resilient system that is good for business, people and the environment.

A circular economy is about minimizing waste and making the most of the scarce resources on our planet. We can minimize the resources needed, waste, emissions and energy consumption through long-lasting design, maintenance, repair, reuse, re-manufacturing, refurbishing and recycling. Extending the life cycle of the equipment and optimizing industrial processes so that environmental efficiencies, such as better energy efficiency, can be achieved are also part of the circular economy concept. Taking back, leasing and reselling products is also a growing aspect in the world of scarce resources.

Supporting circularity is an important part of our business model.​​​​​​​ We can impact resource scarcity, waste, emissions and energy consumption in many ways, and the methods are continuously developing. Our equipment is built from strong and durable input materials, ensuring a long product life and minimizing the environmental impacts during its lifetime. We offer products that make crushing demolition waste possible, thus allowing the use of this waste to be more effective. In addition to environmental benefits, circular solutions are commercially attractive to our customers, as equipment wear and tear can cause considerable direct and indirect costs.

Recycling of electronic scrap

One of our circular economy solutions is focused on the recycling of electronic scrap such as printed circuit boards and electronic devices. Globally, this is one of the fastest growing waste streams. They contain copper, gold, and other valuable metals. As primary raw materials are being depleted, there is an increasing need for safe and ecological reuse of both primary and secondary raw materials.

When properly treated, these complex raw materials can be recycled and reused. Metso Outotec is here to help our customers face these challenges, with solutions that address the following:

  • ​​​To treat e-scrap safely and efficiently, it is important to use automated smelting solutions that are complemented with highly efficient gas cleaning and wastewater treatment. Compliance with the strictest environmental regulations is essential.
  • High recovery and process availability are important. Metso Outotec can offer this for a wide variety of secondary raw materials - and even for the refined metal product.
  • Metso Outotec can support customers on the development of a complete e-scrap treatment process flowsheet, technology, commissioning and advisory services.

The recycling of asphalt and other demolition waste, as well as the use of manufactured sand, is quickly increasing in popularity. Tearing down an old building means new life for its materials. Renewing the road pavement means tons of reusable asphalt. The construction waste recycling professionals have an important job in making circular economy a reality. Metso Outotec is a recycling specialist with decades worth of experience. 

Material efficiency

Construction waste consists typically of concrete and brick, rebar, wood, plastic, gypsum and insulation materials. Iron has a high reuse value, and it is easy to separate with the correct tools. Also, lighter materials such as wood and plastic can be separated and recycled, while the concrete gets crushed and screened to specification. Crushed concrete lends itself to many uses such as filling, road base and riprap. Reusing fossil bitumen, as well as aggregates in recycled asphalt, makes sense both financially and environmentally. Our impact crushers are ideal for concrete and asphalt crushing.  

Processed slag, a byproduct of steel making process, is a valuable material in many different applications. It can replace 30–50% of the cement in concrete, used as aggregates, ballast and insulation material. 

Material efficiency also means using the available resources better — using reduced amounts of primary raw materials and substituting them with secondary raw materials recycled from the original process. Increasing the use of recycled content of raw materials is an efficient way to reduce the total environmental impact resulting from the production processes.
