A Systematic Literature Review of Biofuel Synergies
2010 (English)Report (Other academic)
Often biofuels are criticized in the media for their low production energy efficiency, environmental impacts and by using food for fuel production. An answer most critics rely on is stating how 2nd generation biofuels will solve all the problems the first generation biofuels possess. However, 1st generation biofuels must “pave the way” for 2nd generation biofuels. They can do this by providing the infrastructure, technology and knowledge provided by the fuels.
In order to increase the efficiency of 1st generation biofuels, the theories of industrial symbiosis can be applied. Industrial symbiosis theories are designed to integrate production systems and other industries to improve energy efficiency and environmental performance. By integrating biofuel production systems, the by-products of biofuels can be used in subsequent processes. By making use of by-products, excess heat, etc. the energy efficiency can be improved and allow for more benefits including economic and environmental performance.
Industrial symbiosis literature includes many examples of how industries can benefit from one another but does not include much literature on the integration of biofuels. Synergies do however exist as there are many by-products which are highly prized in other industries, e.g. glycerol and DDGS. The biofuels themselves can even be used in subsequent processes.
The aim of producing this literature study is to find relevant biofuel synergies1 within various fields from scientific literature. By searching for keywords and combining these with keywords related to biofuel synergies we can review the extent and knowledge of synergies between external industries with biofuels, between biofuel industries and the use of their byproducts throughout various research fields.
The main research questions to be answered are:
- What do other research fields use biofuel by-products for?
- What are the current trends for the use of biofuels and their by-products?
- What substrates/by-products/wastes from other industries can be used for biofuel production?
- Which synergies exist in the literature beyond those presented in other phases of the research project?
- What are some potential uses for biofuels, their by-products and industrial wastes and utilities to integrate in symbiosis?
