Waste to raw material


Selling process waste and by-products to other companies that can use them as raw materials has seen ASSA ABLOY engage in a process of industrial symbiosis that is mutually beneficial and minimizes environmental impact.


ASSA ABLOY has traditionally generated revenue from process waste by selling metal back to suppliers, while the majority of other waste is recycled, burned for district heating or sent to landfill. Waste that does not generate revenue can often be quite costly to dispose of, as well as having a potentially negative environmental impact.


Industrial symbiosis is an association between two companies in which the waste or by-products of one company become the raw materials for another. Many Group companies are developing associations with firms that can utilize our by-products as input for their own raw materials. For example, ASSA ABLOY UK collects waste plastic from injection molding and sells it back to the supplier and Mul-T-Lock in Israel generates revenue by selling its waste carton packaging.


Regarding waste, reduce and reuse should be the first choices before recycling. Recycling, although environmentally beneficial, can be costly and carbon intensive. All waste can be an input raw material for something – metal, plastic, wood, glass, paper, cardboard and organic waste can be used as input materials elsewhere. Companies utilizing industrial symbiosis opportunities are using waste by-products to generate revenue and minimize environmental impact, as well as benefitting from the future cost avoidance of increased recycling and landfill costs.
