Active Solar Energy Storage (ASES) is an active heat storage system for low- and zero-energy buildings. It is a unique energy system that utilizes, seasonal stores and recycles the sun's energy for heating and domestic hot water in buildings during the winter.

This Algae pilot is the first of its kind in Sweden. The algae convert unwanted substances to utilities. The goal is that algae cultivation will reduce our emissions of carbon dioxide and purify waste water to minimize over-fertilization of our waters and at the same time produce an energy-rich algae mass that is raw material for biodiesel (algae with high fatty acid content), animal feed (protein-rich algae) etc.

At Alsterbro sewage treatment plant, wastewater is purified in three steps.

The heating and cooling system of the hospital in Kristianstad uses energy from an aquifer in order to heat the hospital in winter and cool it in summer. This is a unique clean energy solution that uses “free energy” in a creative way. The solution was developed by Region Skåne in cooperation with the company Malmberg Water.

Arlanda Airport has managed to reduce its emissions of carbon dioxide with 50 %. A strong contributing factor to the reduced emissions has been the investment in geo energy, which is taken from an underground aquifer.

Since 2003 the waste water from the town of Trosa (about 4500 citizens) has been treated in artificial wetlands, after the basic treatment in the sewage plant. Thanks to the wetlands the Trosa river and the town bay have been spared from eutrophicating substances (plant nutrients) as well as contagious substances (pathogenes). Besides the value of purifying the water, the wetlands are a popular recreation area. The wetlands are used for education and many study visits are made here.

Developer and supplier of high-tech systems for cost efficient pre-treatment of biomass for use in heat and power generation, conversion to liquid fuels and production of green chemicals. Based on over ten years of research, BioEndev has developed an innovative torrefaction technology for production of black pellets. With over 10 patents we have a unique technology with high process control and availability. Black pellets resembles fossile coal in many ways but is renewable and carbon neutral. Black pellets are hydrophobic and has up to 50% higher energy density compared to white pellets.

The biofuelled CHP (Combined Heat & Power) plant is one of Göteborg Energi’s most important heat production plants. It also holds the control room for the entire district heating system of the city.

In a unique project, Fortum provides Nynas AB refinery in Nynäshamn with process steam, coming from the biofuel-powered cogeneration plant. In return, Fortum is given access to the surplus heat from the refinery, which they will use to heat Nynäshamn’s municipality. This project will result in reduced emissions of carbon dioxide, with nearly 100 000 t / year.

Öresundsverket in Helsingborg treats the wastewater from the 140,000 inhabitants through a biological process.

Extraction of compostable soil from household waste

In Trosa Marina there is a boat-washer, which scrubs off the fouling on boat hulls. Thanks to the boat-washer, the boat-owners do not have to use environmentally-hazardous anti fouling paints anymore.

Purification of waste water in Borlänge

In Borlänge there are two waste water treatment plants

Braås heat plant, operated by Väsjö Energi AB, produces about 17 GWh per year and supports 113 customers.

The district heating plant in Bålsta supplies Håbo municipality with environmentally-friendly heat and hot water. The plant consists of three boilers: a wood chip boiler, a pellet boiler and an oil-fired boiler, which together represent 80% of the plants total energy production. The remaining 20% are taken from a adjucent gypsum factory, whose waste heat is led to the boiler through pipes.

If you want to know how business and society inspired by Cradle to Cradle can contribute to healthy living environments, then visit Cefur Showroom in Ronneby, southern Sweden. Every company exhibiting in the Showroom is on a journey that will gradually improve the environment while stimulating the economy and corporate growth.

The EU’s largest smart energy cities project, CELSIUS, has taken a leading role in demonstrating and promoting smart district heating and cooling solutions across Europe. More than 60 cities have now joined the project, coordinated by Sweden’s largest municipal energy company Göteborg Energi and the city.

To improve accessibility in the city centre, a joint goods reception for smaller deliveries to downtown shops has been established.

The city, property owners, transport companies and stores have collaborated to simplify regulations, establish walking speed areas and intensify checks. As a result, it is remarkably easier to distribute goods in the city while traffic intensity, noise and emissions have decreased. The participant response has been consistently positive and the model has attracted interest from other cities in Sweden and internationally.

Clean public transport initiative

The Clean Vehicles Poject started in the mid 90’s, originally to acquire environmentally friendly cars for the municipality. This led to the development of an infrastructure for the supply of clean vehicles and bio fuels. Since then, a considerable number of cars have been bought, tested and evaluated and the supply of clean vehicles and bio fuels has increased successively.

Two sewage treatment works in Stockholm are producing biogas from sewage sludge. After having purified the gas, it can be used for both heating and vehicle fuel and in addition creates no net emissions of carbon dioxide. Consequently, the treatment works have reduced their amount of emissions and become energy suppliers. Therefore, sewage sludge is no longer an environmental problem, but an important energy resource.
