bio-bean Ltd is an award-winning clean technology company that has industrialised the process of recycling waste coffee grounds (WCG) into advanced biofuels. bio-bean offers a novel solution to WCG disposal, which typically end up in landfill where they degrade and contribute to the UK’s greenhouse gas (GHG) emissions. Instead, WCG are collected across the UK and recycled into Coffee Logs™ and biomass pellets at bio-bean’s factory in Cambridgeshire.
In 2016, bio-bean carried out a high-level impact assessment of its biomass pellets to understand the carbon emissions associated with their production and provide a comparison against conventional waste disposal methods and fuels. As anticipated for a fast-growing technology company, bio-bean’s operations are constantly developing, and this assessment quickly became out of date. With growing stakeholder interest in the environmental benefits of its technology, bio-bean needed a flexible approach to calculating its product carbon footprint that would ensure the stated emissions were an accurate reflection of the company’s operations at any given point in time and could model future changes made to its operations and products.
bio-bean sought support from Avieco to overcome this challenge and develop a dynamic product carbon footprint tool that assessed the carbon impact of Coffee Logs and biomass pellets. After kicking the project off by interviewing key members in bio-bean’s production, procurement, and logistics teams we took the following steps:
1. Product carbon footprint tool:
2. Opinion statement
Having received assurance for the carbon footprint of its Coffee Logs and biomass pellets, bio-bean is now able to confidently state the GHG emissions associated with its solid biofuel products, and communicate the environmental benefits of its technology over alternative waste disposal methods. Sharing this information with investors, WCG producers and sales customers can be done so succinctly with the issued opinion statement. In addition, bio-bean now has an approach for achieving verification of its product carbon footprints in future years, which is supported by our product impact assessment tool.
our product impact assessment tool provides bio-bean with a breakdown of its emissions at a production stage level and gives visibility of its “carbon hot spots”, where future efforts should be focused to reduce emissions and improve the overall environmental performance of the products.
The tool gives bio-bean the flexibility to model changes to its existing operations and enhances the company’s understanding of the resultant carbon impact that these changes could have. It also supports the company’s key decisions with respect to its raw materials, procurement, operations and even new product ranges, aiding bio-bean to consider and explore the environmental impacts of its operations in greater depth and across a wider range of business activities than was initially possible.
