Chemical building blocks from versatile MSW biorefinery

PERCAL will exploit Municipal Solid Waste (MSW) as feedstock to develop intermediate chemical products at high yield and low impurity level with huge industrial interest. These will be complementary to the bioethanol (current PERSEO technology), to achieve a cascade valorisation of the MSW components, i.e.:

• Lactic acid (LA) to produce: 1) Eco-friendly ethyl lactate solvents by reactive distillation from lactic acid & bio-ethanol to be used in cleaning products and inks and 2) hot-melt adhesives for cardboard and other non-food applications in combination with maleic anhydride by reactive extrusion.

• Succinic acid (SA) as an intermediate building blocks to production of polyols for the polyurethane industry.

• Biosurfactants by chemical and/or microbiological modification of protein and lipid fraction from remaining fraction of MSW fermentation.

Overall Objectives

To improve enzymes cocktails to maximize organic hydrolysis for several MSW compositions.
To determine the suitability of a given MSW organic composition for different chemicals
To study the production and purification of LA from MSW using sequential and simultaneous saccharification and fermentation
To study the production and in-line purification of Succinic Acid (SA) from MSW using membrane electrolysis technology.
To valorise the fermentation by-products in order to increase the recovery from the organic content of MSW by 25 %
To extend esterification to a Continuous process with a yield of 3-5L / h; Product Purity › 90%
To produce hot melts based on lactic acid for application in cardboard and labels by reactive extrusion With similar resistance to analog EVA HMA.
To produce polyether and polyether polyols for application in polyurethanes (PUR). Objective 1,000 MW, compatible with petrol-based polyester / polyether polyols
To study the integration of in-line control technologies to the PERSEO pilot plant to increase its process control parameters, its versatility & maximize homogeneity of the fermentable feedstock
To demonstrate safety and regulatory compliance, as well as the environment and economic Sustainability of developed processes and products
To define sustainable value chains and cross-sectorial connections
To maximize the innovation impacts of the project for contributing to the uptake of the project results for companies’ business and employment growth

PERCAL consortium

PERCAL consortium has a well-balanced composition. It brings together a wealth of expertise and resources within the areas, including partners that propose the best solutions to maximize the valorisation of the different components of MSW. The presence of main actors in the whole value chain demonstrates the critical mass of complimentary resources that will enable the PERCAL project to achieve its targeted societal, industrial, and scientific breakthroughs and commercial success.
