List of questions 

The foundation of the AIMday concept is to match questions from industry with relevant research competence. These questions are made the subject for discussions in small, multi-disciplinary groups with one hour per question.

    Help us to identify how we can implement a circular economy within Type 31 programme/ shipbuilding

    At Babcock we design and build complex platforms and marine system. The design and build of frigates, such as Type 31, requires great engineering and production efforts, taking 7/8 years in total. We are looking as to how we can develop a sustainability shipbuilding strategy and advice on how best to implement a circular economy in different areas.

    How do we unlock private investment to restore ecosystems & capture carbon across Scotland whilst ensuring a Just Transition to Net Zero?

    The quest for carbon offset amongst multi-national companies has created a new kind of “green-laird” where the aggregated land-ownership profile of Scotland is perpetuated in the rush for land on which to sequester carbon. The challenge is to how to harness investment to create green jobs, resilient communities and regenerative businesses that support nature and people. In May 2020 the Scottish Wildlife Trust (SWT) and Scottish Environment Protection Agency (SEPA) launched the £Billion Challenge which pioneers how to finance the restoration of the ecosystems that support us all – the most important challenge of our generation. The challenge is exacerbated by the fact that Nature Based Solutions (NBS) to climate change fall outside of the existing innovation paradigm and funding support systems. Our Highland Boundary business is part of the £Billion Challenge network and is working to fund an expansion of our regenerative, triple-bottom-line enterprise that will support re-generation of biodiversity, capture carbon and create green jobs. We would be grateful for help with creating new business models that enable the systems change to a liveable future.

    Can the academics discuss the suitability (from a technical, commercial and sustainability perspective) of fermentation as a unit operation in the upgrading of waste products (including CO2) into higher value products

    As a process licensing company, JM want to offer state-of-the-art routes to chemical products – the viability of fermentation in these processes remains open to question and we would like to discuss how to advance this with a multi disciplinary team, if possible.

    Taking into account that distilleries are visited by many tourists, what technology is available (with exception of Xanthella / Dry Ice Scotland) that can utilise fermentation CO2?

    The Scotch Whisky sector is looking to make use of its fermentation CO2 and currently there’s only a few companies that can utilise it – Xanthella and Dry Ice Scotland. I’m also aware of CO2 fixing in building materials/minerals.

    What opportunities exist for exploiting academic expertise in Low Carbon material solutions for traditional Scottish buildings?

    A significant proportion of our Scottish public Estate & Buildings are traditional stone construction with carbon footprint challenges. Significant progress is being made in the adoption of sustainable building materials/practices in construction using re-cycled brick, timber, glass and emerging plastic based technologies but less so in the adaption and re-use of stone.

    ‘What is the potential for resource recovery from wastewater waste streams, using thermal or thermochemical conversion to produce biochar and biochar-based composites, for carbon sequestration and other environmental applications?’

    Scottish Water is trying to progress its understanding of the potential of the value of biochar and its potential uses and benefits to SW. We are especially interested in biochar created from our own waste stream(s) – not just sludge – for carbon sequestration.

    What circular solutions could be deployed to reduce the impact of the displacement or removal of soils from infrastructure project sites?

    Infrastructure projects often lead to large amounts of soil being displaced or removed. We would like to explore the most circular options for the reuse or enhancement of excess or displaced soil. This would require strategies for assessing the quality and characteristics of the soils (including their current and future carbon sequestration ability), as well as ways of quantifying the potential ecosystems benefits of a new approach.

    [CLOSED SESSION] Question 1 online: Can we use biochar as a peat-replacement?

    Peatlands are significant carbon stores, and its harvest for use as a soil amendment leads to high CO2 emissions and the degeneration of important plants and animal habitats. How do we accelerate the necessary movement away from peat? Can we use biochar as a peat-replacement? Can biochar be used to replace peat in other applications than as a soil amendment? Can we use biomass waste to produce the biochar, then produce a soil media that can be used in controlled growing environments, which can then be spread back onto the fields?

    [CLOSED SESSION] Question 2 online: How can we use ‘contaminated’ feedstocks to produce biochar?

    To date, a majority of biochar is produced from ‘clean’ woody feedstocks and has an end use as a soil amendment. How can we use ‘contaminated’ feedstocks that are destined for landfill (e.g., municipal waste, plastics etc) to produce biochar? Can we use this material as an alternative feedstock, and use the biochar in end uses such as concrete, asphalt, or even put back into landfill. The pyrolysis process reduces the weight and volume of the waste feedstock material, and may have a potential co-benefit that adding biochar to landfill sites might suppress greenhouse gas emissions.

    [CLOSED SESSION] Question 3 online: Can biochar be used in co-deployment with enhanced weathering on agricultural or forest soils to promote sequestration of both inorganic and organic carbon, and act as a slow-release fertiliser?

    Biochar, due to its high cation exchange and water retention capacity, can enhance soil organic carbon sequestration. Likewise, spreading crushed silicate rock on soils can enhance CO2 removal from the atmosphere in the form of inorganic carbon via enhanced weathering, and release nutrients such as potassium, phosphorus, silicon etc. Can biochar be used in co-deployment with enhanced weathering on agricultural soils to promote sequestration of both inorganic carbon (from enhanced weathering) and organic carbon, as well act as a slow release fertiliser?
