’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.

The original since 1991, installed in more than 35 countries

For almost 30 years, the Big Hanna composters have demonstrated their efficiency in local composting of food waste. They can compost all food waste including meat, fish, dairy products, garden waste and most compostable organic matter. Big Hanna Composter was named ALEtrumman when the first installation was made in 1991. Now we are using only the name Big Hanna which has been in use for the last 20 years or so for our export markets. ALEtrumman/Big Hanna was invented by Torsten Hultin, a Swedish sociologist. Since the first installation there has been many more around the world – take a look at the ‘References’ pages and our ‘News blog’.
