Composting with Big Hanna – this is how it works
Simple and practical
It is simple and practical because the most unpleasant fraction of the waste stream – the food waste, is being dealt with hygienically on a daily basis. You empty your food waste into Big Hanna Composter every day. The average process time inside the machine is 6-10 weeks. The aeration and turning is done automatically which means that the natural decomposition process works perfectly from start to finish. The finished compost is automatically fed in to a bag or bin ready to be mixed with soil or put on maturation bay. The composting process takes place in an in-vessel composting unit so there are no unpleasant odours on-site. Our customers have all high demands on an economical and functional handling of food waste. We have a vast experience from our many installations and can make sure that the whole chain, from food waste to compost, works as smoothly and simple as possible.
100 kg food waste becomes 20-30 kg peat free, high-grade compost
’Natural process’ – gives you the most mature compost
The product that comes out from Big Hanna has been in the cylinder for 6-10 weeks. It is not heated up, the heat is generated naturally – we only aerate the material. No chemical or biological additives are used – only sawdust, wood chips or pelletized sawdust. It is not accelerated in any way, it is not done in 5 minutes – it is a natural process – which will give you a mature high quality compost. Because we keep the material inside the cylinder for so long the compost that comes out is stable (not smelly) and does not need further aeration or turning like the product from many other systems need. This is one reason the Big Hanna is well suited for use in highly populated areas. The compost is used as a soil amendment which means there is no need for chemical soil additives (chemical fertilizers) or peat. Compost from a number of Big Hanna’s has been analysed according PAS 100, the UK standard for compost quality, surpassing the quality requirements.
