Material and side stream recovery and processing

Circular economy in industry – from waste to savings

Almost all industrial processes involve side streams – raw materials, wastewater, excess energy and chemicals – that go to waste after the manufacturing process. Today, these side streams can be harnessed for reuse or even processed further as new commodities with business value. There is a growing interest towards the recovery of side streams as for instance in Adven’s ongoing sales projects side stream recovery is considered in around 90% of the cases. Through material and side stream recovery and processing, Adven can help your company build cost savings and even new business. Let’s reveal your opportunities!

New business opportunities through circular economy

In addition to the most traditional industrial side streams, excess heat and wastewater, a significant number of other side streams can be recovered and reused. Industrial by-products can be utilised just as they are, for example, by utilising them as a fuel in thermal energy production. By-products contained in the side streams can also be processed further to increase their value and bring additional revenue, for example, nutrients concentrated from wastewater or sludge can be used as fertilizers in agriculture. Adven always finds the solution that makes the most sense to the customer, and that rolls both environmental and profitability benefits into one.

In nutrient or raw material recovery Adven uses for example MVR evaporation, which is implanted as an integral part of the customer’s production process. More about MVR evaporation.

Biogas production from side streams

Industrial side streams are often taken to a third party to be disposed, although companies could utilise particularly the side streams containing a lot of organic by-products on site in the form of biogas, as a fuel for steam production. The thermal energy contained in biogas can be utilised efficiently while the company avoids gate fees on biowaste, the costs related to the primary energy and the transport of the fuel used for energy production. And in the best-case scenario, at least part of the wastewater fees can also be avoided, if wastewater sludge is used locally in biogas production.

By implementing closed cycles on industrial waters, it is possible to open totally new avenues to significantly improve water efficiency.
