OPINION: ‘Innovative tech could ease Scottish waste crisis’

Dr Stephen Wise, chief strategic development officer at Advetec, makes a case for turning to innovation, such as aerobic digestion, to lessen the impact of the Scottish landfill ban.


OPINION: The BBC’s coverage highlights the huge capacity gap facing Scotland’s waste sector – and its knock-on impact on England’s infrastructure, too. Landfill tax and gate fees are soaring, and the lack of capacity is driving the cost of refuse-derived fuel (RDF) through the roof. It’s a critical moment for the industry to embrace innovation.

Dr Stephen Wise, Advetec

Scotland is full of rural locations and remote communities, so it needs local, flexible, scalable, and innovative waste treatment solutions that can be delivered quickly to drive change at the rapid pace required. Sending waste over the border into England is not the answer, as it’s both carbon and cost-prohibitive.

Having spoken with several Scottish waste handlers, the real cost of sending waste to EfW in England is the £150 per tonne gate fee, plus at least another £50 in transportation. This is completely unsustainable, particularly for small to mid-sized waste handlers. Nor does it tackle this non-recyclable waste stream meaningfully. There must be an acceptance that traditional disposal routes are economically unsustainable and environmentally unacceptable.

At Advetec, we’ve long championed the role of science and technology in reshaping waste treatment, and repeatedly shared our concerns about how Scotland will deliver on its biodegradable municipal waste ban without a change in approach. Innovative technologies, such as advanced aerobic digestion, can significantly reduce the volume of waste sent to landfill or EfW while cutting emissions, providing measurable ESG benefits, and accelerating the journey to circularity. Plus, it presents a local solution, meaning Scotland could process waste on its own soil, without lengthy drives or hefty costs.

For a long time, innovation has been seen as either something risky or an optional extra, but it’s neither. It is essential for survival, compliance, and sustainability in a changing world. Scotland really must be bold, collaborative, and urgent in adopting new approaches.
