We are 13 partners that have come together to bring the best of our expertise to achieve our goal of “Exploiting Municipal Solid Waste as feedstock to develop intermediate chemicals at high yield and low impurity”. We are developing Succinic Acid, Lactic Acid, and bioethanol. These intermediate chemicals serve for the production of highly valued products such as biosolvents, cleaning products, holt melt adhesives, polyols, biosurfactants and many more.

We progress every day and meet every six months to measure our results and strategically plan our next steps. For the 6th month PERCAL General Assembly we met in Athens at the Agricultural University of Athens on the 17th and 18th of January. AUA leads succinic acid purification tasks and the environmental, regulatory and economic analyses’ activities. AUA also participates in the Microbial Conversions of MSW of succinic acid.

At the meeting, the partners revealed important progress within the project work packages. Here below you can see a list of the meeting highlights:

  • We have a new partner

YPAREX is joining the consortium bringing expertise in extrudable adhesive resins in multilayer applications. Yparex® is a product family of The Compound Company. The Yparex® portfolio consists of a full range of high-quality, high-tech tie-layer resins, coupling agents, and compatibilisers, that meet the demanding needs of customers in a broad range of application areas. 

  • Bioproducts requirements were presented

Within the tasks in the WP1 related to characterisation, handling and pre-processing of Municipal Solid Waste, the requirements for the selected products were discussed. We will produce bioethanol, Lactic Acid, Succinic Acid and Surfactants for the window cleaners, printing inks, PLA, polyols, and polyolefins.

  • Food waste recipes and real MSW

The consortium is looking at the best waste methods in order to analyse the optimisation of the processes. As of now, partners have sent waste samples from various countries as the project requires the testing of real MSW which comes mainly from food, kitchen as well as garden and park waste.

  • Initial fermentation for microbial conversions to lactic acid

Trials have been carried out showing good performance of the process. After 10 hours of fermentation, the maximum values expected were achieved. Other alternatives are being tested and considered.

  • Initial sugar concentration achieved for microbial conversions to succinic acid

The current work is determining factors that affect succinic acid extraction. Initial tests on sugar concentration were carried out for all strains.

  • Initial analysis of fermentation by-products to produce biosurfactants

Calculations and required amounts of each fermentation by-product to produce biosurfactants started in February 2018

  • Video and other dissemination, communication and exploitation activities

The first PERCAL video together with promotional material were produced at the beginning of the project (watch our video here). Initial activities to analyse the potential of our processes have begun.

  • ...and our next meeting is coming on 3rd and 4th July.

We will be visiting Potsdam in Germany where our partner ATB will host our General Assembly. The Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB) as a nationally and internationally acting institute is researching the interface of biological and technical systems. In PERCAL, ATB is leading the microbial conversions of MSW to lactic acid.
