TThe problem:
The VAMOS project showcased, at demonstration scale, the feasibility of producing and valorising second-generation sugars derived from municipal solid waste (MSW). MSW is composed of either mixed domestic residual waste or waste rejected from sorting and recycling processes. Even after recycling, MSW contains significant quantities of paper and card-based materials from which second-generation sugars can be produced.
Sugar is one of the most essential raw materials for industrial bioprocessing supply chains. Currently, the sector relies on first-generation sugar from agricultural biomass such as sugar cane or sugar beet. However, this means the supply chain depends on crops that often have a high environmental and social impact and are subject to fluctuations in supply and cost. Second-generation sugars can overcome some of these issues, although do present their own challenges such as higher dilution and lower purity rates.
The VAMOS project will produce second generation sugars from waste. The sugar was used for the production of sugar as a chemical for formulations, and as a fermentation feedstock for the production of lactic acid and subsequent PLA.
The outcomes were:
Reduced levels of waste being sent to landfill
Reduced amount of suitable food producing land diverted to first generation sugar production
Economically viable second generation sugar
Sugar tested in two different product lines to prove its commercial viability within manufacturing
Business plan developed for next steps and commercialisation
Reduced environmental footprint for sugar
Reduced environmental plastic pollution levels
Supporting a reduction in the current high price of bio-based materials
