Eco-cycle solutions in Norrtälje
Thanks to a large-scale installation of composting and a hundreds of separate sewers, the municipality of Norrtälje has managed to reduce a leakage of nutrients with five tons to the Baltic Sea. These actions have raised the property owner’s interest for Eco-cycle solutions and the municipality has gained a valuable knowledge in eco-cycle adapted water and sewage sytems.
The company Schneider suggested a project to Region Skåne that involved installation of new control systems for ventilation, temperature, fans, and sensors for the control of lighting at the hospital in Kristianstad. Savings would be shared between the hospital and Schneider. In addition to installing equipment, the project involved meetings with numerous members of the 2100 employees of the hospital in order to engage them in energy saving changes of behaviour and work routines. It turns out that some 40 per cent of electricity use is determined by employee behaviour and substantial amounts of electricity, heat and money can be saved by involving the whole organization in savings efforts. The project rendered net savings of more than 200,000 euro for the hospital, and it provided a strong confirmation that the pursuit of sustainability and financial interests can be combined.
Environmental investments in Vällingby Centrum
Svenska Bostäder have invested over three million Swedish kronor in an installation for geothermal energy and a recycling central. Thanks to the investment, Vällingby Centrum produces nowadays its own energy, which provides the shopping centre with 60 % of its need for heating and 90 % of its need for cooling.
Filborna Combined Heat- and Power Plant
The Filborna waste-to-energy plant is run by Öresundskraft, the municipality of Helsingborg’s wholly owned energy company. Commissioned in 2013, the plant incinerates a total 160,000 tonnes of waste (RDF) per year in its 70 MW boiler, producing steam for district heating and electricity. The plant boiler features an advanced combustion control system and water-cooled combustion grate, distinguished by its reliability and suitability for Refuse-derived Fuel. The plant also features a state-of-the art, combined flue gas cleaning and condensation system to ensure high efficiency whilst meeting stringent emission requirements. The Filborna plant supplies approximately 40% of Helsingborg’s heating demands.
