Shredder investment reduces fuel consumption by 60% at Waste to Energy plant

Construction and commercial waste management specialist Rabbit Waste Management Ltd has more than halved the energy required to power its shredding line, resulting in cost savings of approximately £60,000 per year.

Rabbit commissioned Yorkshire-based UNTHA’s XR3000C mobil-e shredder in November 2017, in a bid to lower the level of dust, fines, fire risk and noise of its waste processing operation. But the 60% reduced energy consumption has also resulted in significant financial benefits business, not to mention a much smaller net environmental impact.

Rabbit is no stranger to waste shredding. The skip hire firm diverts 75,000 tonnes of locally-collected C&I, C&D and wood waste from landfill each year, in favour of manufacturing an alternative fuel used to run its own 5MW Waste to Energy Enviropower plant.

Rabbit director Duncan Barrass said:“We are an eco-friendly organisation which is why we’ve worked hard to manufacture a renewable resource that can be used to generate electricity.

“But to be a truly environmentally robust business, it is only right that we sought a way to cut the amount of energy needed to run our facility in the first place.

“With 60% less energy consumption, equating to around £60,000 per year, the XR’s impact on our ‘green’ agenda – not to mention our bottom line – is vast.”

With its robust cutting concept, the machine is capable of processing various materials to further reduce the amount of complex waste sent for wider treatment or disposal, and the technology can be reconfigured to manufacture different fuel specifications in only three hours.

Barrass added: “Not only do we no longer need to wear ear defenders – it is also possible to have a conversation, standing next to the XR, when it is running.

“This low noise level was previously unheard of in our sector, but will become increasingly important as H&S, planning and noise pollution laws become tighter and tighter.

“The world of Waste to Energy is fast-paced and frequently changing. The very purpose of it is to produce fossil fuel substitutes that can vastly improve our resource security as a nation. But in pursuing such a ‘green’ agenda, it is important to invest in solutions that enhance the commercial viability of the whole operation. Our shredding overhaul has fulfilled this brief entirely.”
