MyGug Turns Food Waste into Free Renewable Energy

A groundbreaking Irish innovation is redefining what it means to live sustainably at home, offering households the opportunity to turn everyday food waste into renewable energy, reduce their carbon footprint, and eliminate reliance on traditional waste systems.
Developed by Cork-based green technology company AmuGreen, MyGug is a compact, small-scale anaerobic digester designed to sit at the heart of the home. The system converts food waste into clean biogas for cooking and nutrient-rich liquid fertiliser, creating a closed-loop, self-sufficient solution that transforms how households manage food waste.
MyGug Food Waste into Renewable Energy
At a time when households are being urged to take greater responsibility for their environmental impact and when food and energy security are under threat, MyGug offers a practical and immediate solution. Instead of food waste being seen as a burden which must be collected and disposed of elsewhere, significantly contributing to greenhouse gas emissions, MyGug turns food waste into usable energy at home, reducing carbon footprint and supporting a circular economy model of living.
The urgency of this innovation is underscored by the scale of the problem in Ireland. According to the Environmental Protection Agency, Ireland generated approximately 835,000 tonnes of food waste in 2023—equivalent to around 162kg per person, one of the highest levels in Europe.
The system is capable of processing up to 1.5kg of food waste per day, generating enough biogas for up to two hours of cooking. MyGug also creates a nutrient-rich liquid feed which can be used to support plant growth, reducing the need for chemical fertilisers and creating a fully circular home ecosystem. This means households can significantly reduce waste disposal, lower energy costs, and move towards a more self-sufficient lifestyle—all from a single, compact unit.
The innovation was developed by Irish entrepreneur Kieran Coffey, whose vision was to create a practical, scalable solution to one of the world's most pressing environmental challenges. Driven by a commitment to sustainability and resource efficiency, Kieran focused on designing a product that empowers individuals to take control of their own waste while contributing to a cleaner, greener future. His work has positioned MyGug as a leading example of how small-scale innovation can deliver meaningful global impact.
MyGug has already been adopted across homes, schools, and communities, demonstrating its versatility and real-world impact. Designed and manufactured in Ireland, the system operates effectively in all seasons and climates and requires minimal intervention once installed, making it accessible to households seeking to create free energy and reduce their carbon footprint.
Commenting on the system, Kieran says, "We created MyGug to fundamentally change how people think about waste. Food waste should never be seen as something to throw away—it's a valuable resource, beyond convenience; the environmental benefits are significant. By enabling households to turn that waste into clean energy and liquid feed for the garden, we are giving people the tools to become more self-sufficient while also making a real, measurable positive impact on the environment. MyGug can dramatically reduce carbon emissions while also decreasing reliance on waste collection systems and fossil fuels. It's about empowering individuals to take simple, practical steps that collectively deliver significant environmental benefits. In time, systems like this won't be seen as optional—they will be an essential part of every sustainable home."
With a retail price of €3,450 including delivery and installation in Ireland and easy payment options available, MyGug represents an investment in long-term sustainability and circularity at home.. When factoring in savings on waste collection charges, reduced energy costs, and the value of fertiliser produced, households can begin to see a return on investment ov...
