Nutragy is a sustainable, organic, low-carbon fertiliser derived by combining upgraded residues and by-products from agriculture and the bio-energy industry, and provides safe nutrients for agriculture. Our proposal builds on an extremely successful feasibility study that was supported by Innovate UK (Project: 10026757), whereby Stopford demonstrated that...

The management of difficult-to-recycle waste streams is a global issue, resulting in potential resources being sent to landfill or incineration. Singapore's "Zero-Waste" target requires sustainable waste and resource management to drive climate resilience, resource resilience and economic resilience. Nevertheless, population growth and poor recycling awar...

The UK's net zero strategy for decarbonisation requires all sectors of the UK economy to meet the net zero target by 2050\. The UK concrete and cement industry produced 7.3 million tonnes of CO2 emissions in 2018 and currently accounts for around 1.5% of the UK's CO2 emissions \[1\]. Fuel switching to low-carbon fuels in this sector could potentially redu...

This project will develop CircuPlast, an advanced eco-friendly technology, to recycle waste PET-based plastics (e.g., pots, salad trays, and tubs), by converting them to commodity compounds that can be used to manufacture fresh plastics. Currently, only half of the PET waste in the UK is recycled, with the remainder going to landfill or incineration. This...

ECOSMART:2 will demonstrate the smart integration of a novel, enhanced anaerobic digestion (AD) process with solar technology to form the basis of a circular economy model, providing affordable, clean, secure energy access. Through development and operation of the ECOSMART:2 modules, new integrated UK-Nigerian enterprises and supply chains will be establi...

This project seeks to formulate and trial balanced N:P:K fertilisers with trace elements, by combining and processing residues from the bio-energy, agricultural and waste management sectors; digestate and ash. The innovation in this project will be to extract the nutritional and crop enhancing chemical value from these waste streams to formulate a suite o...

This project will seek to assess and validate a novel process technology that will enable the indiscriminate recycling of currently non-recyclable mixed plastics packaging waste and increase the recycled content of plastics packaging, whilst preventing the release of plastics waste into the environment. Using water as a green solvent, CircuPlast, our supe...

This project seeks to fast-track the testing, scale-up and design of a novel mobile microwave induced plasma (MIP) gasification technology, to provide both flexible and additional capacity to enable the safe and sustainable disposal of COVID‑19 related clinical waste. With clinical waste arisings being reported to have increased by 600% in regions of high...

This project will seek to assess and validate a novel process technology that will seek to enhance plastics packaging waste recycling rates and increase the recycled content of plastics packaging, whilst preventing the release of plastics waste into the environment. Using water as a green solvent, our super critical water (SCW) technology aims to enable t...

Increasing the efficiency of energy from waste schemes has been a long-term goal for the sector, especially for advanced thermal treatments (ATTs) such as gasification. Despite ATTs being more efficient than mass burn, there are only a limited number of ATT plants in the UK as the efficiency gains are often to low to overcome high capex/opex costs. We bel...

This project seeks to formulate complete, (N:P:K) balanced, agricultural fertilisers by combining and processing bio-energy wastes; anaerobic digestate, and ash from thermal conversion of woody biomass. The innovation in this project will be to extract the nutritional and land conditioning value from these two waste streams to formulate a product with an ...

There is a real need to de-carbonise energy production in order that Governments meet their obligations to reduce fossil fuel derived carbon emissions and to meet renewable energy generation targets. Using sustainable sources of wood as a fuel is one such method of reducing the CO2 emissions associated with energy production; however, wood has a high mois...
