On 23rd May, IBioIC and Zero Waste Scotland co-hosted an event at the University of Strathclyde to introduce the Scottish Bioresource data model and to build on work already carried out and published in the Biorefining Potential for Scotland report.

The event was very well attended, with 71 participants already engaged in biorefining activities on a wide range of different bio-based resources joining Johan Belfrage of IBioIC and Louise McGregor of Zero Waste Scotland to hear presentations by key players in the field including Zero Waste Scotland, The Environmental Services Association, Biorenewables Development Centre, Xanthella, Celignis, Biopower and Wastewater Wizard.

The Scottish Bioresource data model contains the data used in the recently published 'Biorefining potential for Scotland' report produced by Zero Waste Scotland. The event outlined the type of data which can be accessed from the model, which is currently grouped into four streams; waste, by products, waste water sludge and agricultural residues, and can be analysed by geographic location, as well as by composition, such as how much carbohydrate or protein is available in a region for further valorisation, value and volume.

We are now at the point of taking the next step in the process by starting to focus on creating new value chains based on the opportunities identified in the report. This is a crucial part of the process because, as Louise McGregor explained during her talk, a single company cannot be ‘circular’. This requires a complete supply chain where a by-product of one process becomes a feedstock for the next in the chain and so on until, at the end of the line, the final product is either degraded and returned to the biological circularity or somewhere in the supply chain the material is completely recycled over and over again, in a closed loop.

The programme involved a range of high quality presentations which gave insight into waste management logistics and economics, the value of compositional analysis and techno-economic analysis related to creating new value chains from bio-based feedstocks.

Some of the examples of these provided by the speakers were:
o Milling of dried bioresources in to powders to be used in, for example, food bulking agents or functional ingredients (Biopower)
o Vermifiltration for purification of wastewater and production of protein for fish feed (Waste Water Wizard).
o MSW to butanol and hydrogen (Nottingham University)

The examples cited represent only a tiny fraction of what could be achieved if the idea was scaled up to access larger amounts of feedstock, and thereby make a much larger impact on sustainability by replacing current, less resource efficient, practices.

The event was well received with participants achieving key insights into the next stages on the path towards circularity and enjoying the opportunity to develop new and valuable connections.
