ENERGY SOLUTIONS

Main focus in Energy Solutions is Aquifer Thermal Energy Storage (ATES) which is a great and proven solution by solving a common challenge – energy storage – in distributed energy systems. With ATES system both heating and cooling can be done very efficiently – more efficiently than with other geothermal systems (Borehole Heat Pumps). Borehole systems are usually not even allowed in ground-water areas. ATES investments and operational costs are low. ATES system fits well for two-way energy grids and can be supported with other renewable energy sources.

PlastEco

Dirty plastic waste is a global challenge to be solved. Pyrolysis of plastics as a thermochemical process is an optimal and currently the only way to recycle it to be re-used in petro-chemical industry.

We have established a joint venture PlastEco Ltd to take the challenge to produce plastic oil from plastic waste. The operation at the Salpakierto’s recycling plant in Lahti starts early next year. PlastEco utilizes pyrolysis technology of Enespa AG. Our partner Salpakierto Oy provides the plastic waste and operation site with utility facilities.

The production capacity of the first step is 5 tons per day. Full recycling is reached. The produced pyrolysi oil is used as raw material for petro-chemical industry. The pyrolysis gas of the process is used in a co-gen plant to generate electricity for the process. Pyrolysis coal is used a raw material for infrastructure industry.

SPECIALISATION

Refining Solutions

Nutrient recovery

With energy-efficient drying it is possible to produce valuable organic fertilizers from animal-based manure. Dried manure can be pelletized and hygienized to nutrient-rich products. Similarly, WWT sludge can be dried and further pyrolized for soil-improvers. In pyrolysis all harmful drugs and micro plastics are destroyed but useful carbon will remain in the end-product.

WWT Sludge recycling in cement production

WWT Sludge is generated huge amounts globally. It can be dried and used in cement manufacturing in order to replace fossile fuels and minerals. Sewage sludge has relatively high net calorific value as well as lower carbon dioxide emissions factor compared to coal when treated in a cement kiln. Due to the high temperature in the kiln the organic content of the sewage sludge will be completely destroyed as well as all harmful substances as drugs.

Pyrolysis of Plastic Waste

Dirty plastic waste is a global challenge to be solved. Pyrolysis of plastics as a thermochemical process is an optimal and currently the only way to recycle it to be re-used in petro-chemical industry. Typically more 85 % of the plastics waste is converted to pyrolysis oil.
