Modelling Sustainable Industrial Symbiosis

Industrial symbiosis networks conventionally provide economic and environmental benefits to participating industries. However, most studies have failed to quantify waste management solutions and identify network connections in addition to methodological variation of assessments. This study provides a comprehensive model to conduct sustainable study of industrial symbiosis, which includes identification of network connections, life cycle assessment of materials, economic assessment, and environmental performance using standard guidelines from the literature. Additionally, a case study of industrial symbiosis network from Sodankyla region of Finland is implemented. Results projected an estimated life cycle cost of euro115.20 million. The symbiotic environment would save euro6.42 million in waste management cost to the business participants in addition to the projected environmental impact of 0.95 million tonne of CO2, 339.80 tonne of CH4, and 18.20 tonne of N2O. The potential of further cost saving with presented optimal assessment in the current architecture is forecast at euro0.63 million every year.

Automated summary

This study provides a comprehensive model for the sustainable study of industrial symbiosis, quantifying the benefits of waste management cost savings and reduced environmental impact. Results show significant cost savings and environmental benefits through symbiotic relationships in the industrial sector.
