Revive is a Scottish company driving the circular economy forward with their focus on the conversion of waste streams into valuable products. The company has already developed a patented process, extracting coffee oil from spent coffee grounds. The technology has since been applied to additional food manufacturing waste streams, showing the value and wide application potential of the process. Revive's vision is to fully valorise feedstocks for their full commercial potential and maximise the environmental impact of their developments. Revive is currently engaged with several global players in the skincare market; their first target market for their sustainable ingredients. Their project, _Upcycled Coffee Peptides: A Sustainable Future for Bio-Based Cosmetics_, will take the valorisation of the spent coffee ground biomass in Scotland even further. The residual, defatted material from Revive's lipid extraction process is a promising sustainable and upcycled source of protein, which can be used as an alternative to animal and virgin crop derived peptides in personal care. Peptides have transformed the cosmetic industry in recent years with their extensive potential for improving skin health. Peptides have a wide range of biological activities making them useful ingredients in skincare formulations. Animal-derived proteins such as keratin, elastin, and collagen are well-established ingredients. However, the use of these ingredients brings its own ethical concerns. An alternative to this is the use of naturally-derived peptides. However, the use of virgin resources where there is increasing biodiversity loss, land degradation, and food insecurity is insensitive to the climate crisis and is not an environmentally sustainable business model. These issues could be combatted by the use of synthetic peptides, but this does not satisfy the demand for sustainable peptides of natural origin. Revive is inspiring a new wave of truly sustainable cosmetics with their innovative approach to producing ingredients. The project will evaluate the protein content of the defatted residue by assessing different green-chemical and enzymatic extraction techniques. The optimal protein extraction process will be chosen, and the product will be isolated and purified into a cosmetic-grade ingredient. Finally, the product's efficacy will be assessed for personal care applications. This project will work towards creating a true circular economy model by demonstrating the extensive value of commonly discarded materials. Furthermore, Revive hopes to enter an untapped market for truly sustainable natural cosmetic ingredients in which no animals are harmed, no additional food sources are farmed, and valuable materials are retained from decomposing in landfill.

The hospitality sector has been one of the hardest hit industries from COVID-19\. Therefore, action is needed to help cafes and restaurants that have been damaged by the pandemic, and the resultant lockdown, to recover. UCGs cost the hospitality sector around £70m per year in waste management costs, with the vast majority ending up in landfill adding huge volumes of greenhouse gases to our atmosphere. Revive Eco Ltd. (Revive) is a Glasgow based startup, on a mission to maximise the value of materials previously thought of as waste. We collect used coffee grounds (UCGs) from across Scotland, saving our customers money on their waste management costs. UCGs contain a range of high-value triglycerides. Triglyceride derivatives are most often used in cosmetics as an emollient or an emulsifier. As an emollient, triglycerides help to enhance skin-hydration by sealing in the skin's moisture and reducing evaporation. Triglyceride derivatives emulsification properties serve as a thickening agent for skincare products. This allows ingredients with differing solubility to form a more consistent solution. Overall, triglyceride derivatives are highly beneficial to infuse into personal care products as a way to provide better spreadability as well as alleviate skin dryness. Unfortunately, these ingredients are normally sourced from environmentally questionable sources such as palm oil. Palm oil's carbon footprint and its association with deforestation have made it a morally questionable product to use for some time. However, with a huge increase in ethical consumerism and anti-palm oil campaigns, it is now becoming economically questionable as well. We, therefore, can provide these industries with a sustainable and locally sourced alternative to ingredients that are currently receiving a lot of negative press. Then, from the residual material left over from our process, a soil conditioner product will be created making the process a truly zero-waste process. We are at the end of a 18 month R&D project funded by Zero Waste Scotland, that allowed us to design and build the first stage of our processing technology. This allows us to dry the UCGs and extract volatile compounds from them in an extremely cost-effective and energy-efficient manner. This has allowed us to establish a small pilot processing facility in Glasgow. The aim of the proposed project is to develop a further process to extract, separate and purify the valuable triglycerides that are normally sourced from environmentally questionable sources, from UCGs. Funding will create four highly skilled jobs, bringing in a wealth of knowledge and experience that will catalyse our development work and allow us to commercialise more quickly and efficiently. It will allow us to develop a truly impactful and innovative new business model one that sees us extracting the absolute maximum value from what was previously viewed as a waste.
