Why It Matters
Waste‑wood biomass is a critical source of reliable, low‑carbon baseload power and a major carbon‑removal tool for the UK’s net‑zero agenda. Ensuring a smooth policy transition now prevents landfill, protects energy security, and safeguards a sector that could deliver a sizable share of future emissions reductions.
Key Takeaways
- •RO support ends 2027, risking waste‑wood plant closures.
- •3 Mt waste wood currently fuels power for 1.5 M homes.
- •Oversupply may force exports, increasing carbon costs.
- •New greenhouse‑gas removal model needs carbon‑cluster proximity.
- •Interim policy support essential to avoid market collapse.
Pulse Analysis
The UK waste‑wood biomass sector faces a pivotal moment as the Renewables Obligation (RO) sunsets in April 2027. Each year the country generates roughly 4.5 million tonnes of waste wood, with about three‑million tonnes diverted to low‑carbon power generation—enough electricity for 1.5 million households. This domestic feedstock underpins energy security, providing reliable baseload power when wind and solar are scarce. With RO subsidies disappearing, many plants risk closure, threatening a sudden surge of material that would otherwise be kept out of landfill or overseas markets.
Seasonal imbalances have already strained the supply chain. Summer construction drives an oversupply, while winter sees reduced off‑take capacity, creating a delicate annual equilibrium. Recent unplanned outages amplified the imbalance, prompting the Wood Recyclers Association to secure flexible storage regulations (RPS 352 and RPS 361) with the Environment Agency. These measures eased stock‑piling pressures but only marginally curbed export growth; European heating markets remain saturated, limiting the value of any excess wood sent abroad. Exporting domestic waste not only erodes carbon credits but also forces the UK to repurchase power at higher interconnector rates, undermining greenhouse‑gas reduction goals.
Looking ahead, the sector’s survival hinges on a transition to a greenhouse‑gas removal (BEX) business model. Assets must align with regional carbon clusters—only four plants sit within ten miles of an existing hub—so policy must confirm non‑pipeline transport options and deliver interim contracts‑for‑difference to bridge the gap. Immediate, targeted support will be cheaper than losing the baseload capacity and carbon‑capture potential that waste‑wood offers, a contribution equivalent to roughly 17 % of the UK’s 2035 emissions reduction target. Prompt action can stabilise the market, preserve energy sovereignty, and cement waste‑wood’s role in the nation’s net‑zero pathway.
Episode Description
As Renewables Obligation support begins to fall away in 2027, the UK’s waste‑wood biomass sector faces a pivotal moment. In this episode of the Biomass Beat podcast series, Argus' Hannah Adler speaks with Richard Coulson, Biomass Lead at the Wood Recyclers Association, to unpack what this shift means for recyclers, biomass plants and the wider waste‑wood market and what’s needed to secure the sector’s future.
Hear expert insights on:
Why RO closure threatens both waste‑wood capacity and the UK’s emissions reduction strategy.
The causes of the current waste‑wood oversupply and whether relief measures are enough.
The immediate and long‑term policy actions needed to stabilise the market.
