The Kalfresh Bioenergy project has hit a significant milestone – the successful pour of a 32-metre wide circular concrete slab which will support our first anaerobic digester tank.
The Kalfresh project team worked closely with local building company CF & JE Miles to pour approx. 161 cubic metres of low shrink concrete.
Boonah Concrete supplied the concrete across 22 trucks and pumping was by local Purga company Extreme Pumping.
Everyone involved understood the significance of the job – it’s a slab that will hold tonnes of weight as the digestion tank fills with biomass feedstocks such as agricultural and food waste, which will convert to renewable energy.
Anaerobic digestion is a natural biological process that breaks down organic waste in a sealed tank without oxygen to create renewable biogas and fertiliser. The biogas is versatile and can be used for heat, electricity and vehicle fuel.
The team started pouring at dawn, one pour, 200mm deep, no joins. Each load was tested on site for strength and shrinkage before the pour.
The bioenergy tank equipment is being supplied by German bioenergy specialists WELTEC BIOPOWER and will start taking shape from mid September.
