ROCKBROOK A.D. LIMITED

Rockbrook AD Limited is a pioneering renewable‑energy specialist that turns organic waste and by‑products into clean power and valuable fertiliser. Based in Ballyroan, Co. Laois, the company operates a state‑of‑the‑art anaerobic digestion (AD) plant which breaks down waste in an oxygen‑free environment, producing electricity, heat and upgraded biomethane, while the residual digestate is processed into nutrient‑rich bio‑fertiliser for farmers and businesses.

The core services offered include waste‑to‑energy conversion for a wide range of sectors – from retail and hospitality food‑waste streams to agricultural manure, slurry and crop residues, as well as industrial and manufacturing waste streams. Rockbrook AD also supplies a district‑heating system that provides free heat to the local church and the Sue Ryder Home, demonstrating a tangible community impact. Clients benefit from reduced waste‑disposal costs, reliable renewable energy supplies, compliance with sustainability targets and a circular‑economy solution that minimises waste while maximising resources.
