From Broken Pallet to Biofuel: The Second Life of Waste Wood

Imagine a broken pallet, past its prime and destined for the dump.  Believe it or not, that pallet, along with countless other wood scraps – broken chairs, left over construction materials, anything made of wood – can be reborn as a clean-burning fuel source. 

This process, called biomass recycling, turns waste wood into chips or pellets that can be burned to generate electricity or heat.

There’s one catch though: wet wood burns poorly. For efficient use as biofuel, the wood chips or pellets need to be dried beforehand. Unfortunately, this drying process can be expensive and contribute to air pollution.

SUEZ, a major UK player in biomass production, encountered this challenge firsthand. The unpredictable British weather meant their woodchip was getting wet before they could be shipped to customers, meaning they had to pay to transport water.

Their answer? A massive Zappshelter mounted on shipping containers. This keeps the woodchip dry, reducing drying time and costs, and allowing them to sell more chips faster.

At 17m wide and 37m long, this setup creates a large storage area which can be extended or relocated in the future, as their requirements change onsite.
