About us

We make heat out of what the woodland leaves behind

Gundi Ltd started in 2019 with one pellet press and a simple idea: Nottinghamshire throws away a lot of perfectly good wood. Today 24 of us turn it into lab-tested pellets at The Fuel Works in Bulwell.

Offcuts in

The feedstock story

Our pellets begin life as sawmill offcuts from Sherwood and the Trent Valley, kiln-dried joinery shavings, oak and beech off-cuts from furniture makers, apple and cherry prunings from local orchards, and (once a year) Christmas trees collected by a Rotary charity drive in January.

Our BBQ range goes further: oak staves from whisky barrels, given a second life with a good smoking.

Every load is weighed and inspected at the gate. Moisture is probed, the wood is checked for paint, glue, nails and treatment, and the supplier's paperwork is matched to what is actually on the lorry.

Quality

Tested, held, then released

Every batch is sampled in our on-site lab and sits on hold until the lab releases it. A UKAS-accredited laboratory checks confirmation samples every month.
