New technologies and early adoption are the keys to sound environmental work. As early as the 1950s, investments were made in a district heating system for Gothenburg. The water is heated using waste heat from sources such as refuse incineration, and is then routed to properties connected to the district heating network. Doing so means that energy which would otherwise have gone to waste in air and sea is, instead, harnessed for good use.
Today, district heating is also produced from the burning of biofuels, and around 90 percent of all apartment buildings in Gothenburg are connected to the network. When the demand for heat is low, waste heat from the district heating network is used to produce district cooling.
Diverse work with green system solutions can be seen on many sites around the Gothenburg region. This includes numerous innovative examples within waste management, urban development and transport.
Gothenburg has opened itself up to the possibility of using the city as a demonstration arena. The ElectriCity project is a collaborative endeavour that utilises this possibility. In addition to electrically-powered bus traffic, the project is also creating a platform for the development of services and products to improve the attractiveness of public transport. The buses run on renewable electricity, there is wifi accessible on board and one bus stop is indoors.
Waste becomes gas
An important aspect of the conversion process is biogas, which is produced through the decomposition of organic waste, among other sources. Gothenburg has one of the world's largest biogas plants. Each year, the plant generates just over 60 gigawatt hours, which are primarily used as vehicle fuel. In order to meet the growing demand for biogas, investments are also concentrated on the production of biogas through the gasification of waste products from forest environments, such as wood chips and fallen branches.
Come and visit
Green Gothenburg is the Gothenburg region's tool for marketing the region's foremost areas within green system solutions. Through Green Gothenburg, regional companies and decision-makers within government and trade and industry are able to visit several sustainable facilities in the region. Unique study tours within construction, urban development, transport, energy and waste management create the opportunities for exchanging knowledge and building new contact networks.
For suppliers of green system solutions ready for export

In Mölndal municipality, a listed factory area is being transformed into a sustainable urban district. Residential properties will be heated using surplus heat from offices and industry. The district will also have its own wind turbines and solar panels.
In Stenungsund, Sweden's largest cluster for the chemical industry, chemical companies will gradually transition over the next twenty years from using raw materials which are 90 percent fossil-based to using entirely renewable materials such as algae, vegetable oils and wood raw material.
In recycling centres throughout the Gothenburg region, large items of refuse are repaired and refined and then sold. These items include furniture, construction materials and other re-usable products.
