What is Kalundborg industrial symbiosis?

The industrial symbiosis project at Kalundborg, Denmark (100 kilometers west of Copenhagen, population of approximately 15,000), is a model of environmental sustainability. In short, it is a process whereby a waste product in one industry is turned into a resource for use in one or more other industries.

How Kalundborg symbiosis works?

Ørsted (formerly known as DONG Energy) owns Asnæsværket, which produces steam, electricity and heat. The steam is delivered to partners in the Kalundborg Symbiosis and in the plant itself, the steam is used to drive turbines which, with the help of big generators, produce electricity for the power grid.

What is Kalundborg model?

The Kalundborg Model Integration of several manufacturing facilities so that the waste material or energy or byproduct produced in one facility can be used in another facility has several advantages. This principle is adopted in the industrial park at Kalundborg, Denmark.

How does Kalundborg industrial park operate?

Kalundborg Eco-Industrial Park is an industrial symbiosis network located in Kalundborg, Denmark, in which companies in the region collaborate to use each other’s by-products and otherwise share resources.

What is meant by industrial symbiosis?

Industrial symbiosis is the process by which wastes or by‐products of an industry or industrial process become the raw materials for another. This process serves to reduce the environmental footprint of the industries involved.

What do you mean by industrial ecology?

Industrial Ecology (IE) is a field of study focused on the stages of the production processes of goods and services from a point of view of nature, trying to mimic a natural system by conserving and reusing resources (Chertow, 2008).

The circular economy is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible.

What is an example of industrial symbiosis?

Examples of industrial symbiosis are wide ranging and include the use of waste heat from one industry to warm greenhouses for food production, the recovery of car tyre shavings for use in construction materials, and the use of sludge from fish farms as agricultural fertiliser.

What is the aim of industrial symbiosis?

Industrial Symbiosis is an innovative approach that aims in bringing together companies from different industrial sectors in order to improve the resource efficiency and sustainability by sharing and reusing resources (NISP UK). This involves raw materials, products, energy, water and also expertise and infrastructure.

What is the principle of industrial ecology *?

The principles of industrial ecology as defined by Tibbs (1992) are: Create industrial ecosystems – close the loop; view waste as a resource; create partnerships with other industries to trade by-products which are used as inputs to other processes.

What is an example of industrial ecology?

Additional examples of industrial ecology include: Substituting the fly ash byproduct of coal burning practices for cement in concrete production. Using second generation biofuels. An example of this is converting grease or cooking oil to biodiesels to fuel vehicles.

Is circular economy good?

When it comes to reducing greenhouse gases, a circular economy can be helpful: Because it uses renewable energy that in the long run is less polluting than fossil fuels. Thanks to reusing and dematerializing, fewer materials and production processes are needed to provide good and functional products.

How many companies are involved in the Kalundborg Symbiosis?

Over the years, more businesses were linked into the Kalundborg Symbiosis, and in 1989, the term “industrial symbiosis” was used to describe the collaboration for the first time. The Kalundborg Symbiosis now has eight private and public partners and involves approximately 50 symbiotic exchanges.

The project promotes industrial symbiosis, a concept for sustainable regional development, across the Baltic Sea region. Industrial symbiosis means to connect companies from different industries in order to use one company’s waste, in the form of e.g. energy, ingredients or materials, as a resource for the next company.

Which is the first symbiosis in the world?
