Processum – Anything Made from Oil Can Be Made from Biomass
An international biorefinery hub. Processum has during a number of years purposefully built up a set of pilot equipment aimed at biorefinery projects. The equipment consists of pilots for thermochemical pre-treatment, biochemical processes, thermochemical syntheses as well as pilots for separations. A broad spectrum of biomasses, like forest raw materials of all kinds as well as industrial residual streams and waste materials, can in pilot scale be converted to e.g. materials, proteins, bioenergy and chemicals. There are also pilot equipment for algae, torrefaction and drying trials in Umeå.
Recycling Park, Kristianstad
The Kristianstad recycling park is one of the best examples of the Swedish system of waste management. The material and energy recycling rate is currently 97% and the goal is to reach 100% in the near future. By increasing the volume of material recycled, the amount of material deposited has been decreased by 40,000 tons. The facility was opened in 2001 and it then replaced a previous landfill site.
Reduction of Hospital Waste
The central hospital in Kristianstad has succeeded to substantially reduce its volumes of waste that is incinerated and has instead started to recycle increasing volumes of paper and plastics. One clinic that had a high rate of recycling at the beginning of the project increased the volume of recycled waste by 300 per cent. The project involved both increasing the volumes of waste that were sorted at the clinics and implementing a system for sorting sacks of waste for recycling and incineration in the hospital’s waste management system. The system uses sacks of paper and plastic of different colours to identify different fractions of waste. The more valuable recyclable waste is now recovered, which saves substantial amounts of money for the hospital.
Restoration of overgrown meadows
At Svartsjöviken in Ekerö municipality, overgrown meadows have been restored. The grounds, which had a low sustainability, were restored with newly developed aphibious vehicles, light band wagons and stump cutting equipment. Today, the meadows are harvested, which has recreated a valuable biotop. At the same time, a long-term parntnership has been established between the municipality, the farmers, the local residents, landowners and various other associations.
Ringsjö Potable Water Plant, Stehag
The Ringsjö plant draws its water from Lake Bolmen through a tunnel that was opened in 1987. The plant regularly delivers 1,600 litres of water per second to 16 different municipalities in the Skåne Region with a maximum capacity of 2,400. The plant itself was opened in 1963 and completely rebuilt between 1994 and 1997, when a new lamella sedimentation basin was added. The process combines lamella sedimentation with a sequence of filters before the final step of pH adjustment with lime water takes place.
Sjölunda Wastewater Treatment Plant, Malmö
Sjölunda Wastewater Treatment Plant, Malmö At the Sjölunda plant in Malmö wastewater from 550,000 inhabitants is treated. The plant was built in 1963. Recently expansion of biological treatment has reduced the use of precipitation chemicals to meet the Swedish requirements and the plant has at the same time reached emission requirements of organic compounds, phosphorous, and nitrogen. The sludge produced is used at the plant’s own production unit for biogas. After a final flotation step for the removal of suspended solids the treated water is released into the Baltic Sea 3 kilometres off the coast.
Sjöstadsverket tests new treatment methods
Hammarby Sjöstadsverket in Stockholm, Sweden, was built as part of the Hammarby Sjöstad initiative, with the aim of halving environmental impact by demonstrating new technology and innovative solutions. The facility is now continuing to serve as a development centre for new water treatment technology.
