Urban Composter - City Compost Bin (8L)The Urban Composter City uses anaerobic composting to ferment your kitchen scraps right in the bucket. This process will minimise foul odours and flies. Simply cut up your food scraps into small pieces, spray with Urban Composter Compost Accelerator Spray and close the lid. Drain the bucket every few days to release excess moisture from the fermentation process. Use this liquid, diluted, to add to your favourite plants as a nutritious liquid
