In recent decades, changing legislation has created a situation where the environmental impact, and cost for treatment of large waste streams has risen dramatically. It is waste that contains organic matter mixed with inorganic in unfavorable proportions. The combustion requires support fuel and causes great wear on combustion plants while the majority of the material forms combustion residues. At the same time these materials contains too high levels of organic material to be disposed of. Hundreds of thousands of tons of this waste is created annually in Sweden, and the situation is similar in many European countries.

The project aims to develop, demonstrate and introduce new treatment methods for these waste products. The development is based on advanced characterization methods and a bank of experiences of various physical, mechanical, chemical and biological processes for waste treatment. The project is expected to result in a more competitive and less environmentally-damaging treatment of three common waste streams with the above-described properties: Safe residue from material recycling from construction and operational waste, dredging waste, and soil contamination from sawmills and impregnation plants.

The project is run in collaboration between RGS 90 Sverige AB and Luleå Technical University.

Flexible Models for Predictive Maintenance


Automation, Digital Twin, Maintenance

Maintenance in existing plants is becoming increasingly important, where predictive maintenance has become an emerging technology. The use of decision support tools contributes to environmentally and economically sustainable production. Within this project, different types of digital twins have been designed and evaluated. Specifically, new predictive model types have been tested in two different industrial case studies; a heat exchanger at SSAB and a profiled header at Svenska Fönster AB.

Positioning technology for the heavy manufacturing industry


Automation, Communication, Digitalization, Security, Working Enviroment

The project aims at radically improving the working environment and the employee security within the heavy manufacturing industries by using and adapting the latest technology for low and ultraprecise positioning and decision support systems. The target is to increase security and safety by adapting the decision-support and positioning system for the heavy manufacturing industries.

Enabling REuse, REmanufacturing and REcycling Within INDustrial systems (REWIND)


Circularity, Eco-efficiency, Recycling, Remanufacture, Reuse

The REWIND project combines the principles of lean production and eco-efficiency in three industry pilots at Stena Recycling, Volvo AB and IKEA GreenTech. The objective is to retain the value embedded in materials with circular strategies (reuse, remanufacture, recycle, repurpose, etc.). Lessons learnt from the pilots will be used to develop educational tools for engineers and industry leaders to accelerate the uptake of best practices for circularity and sustainable production.
