An investment with a future.

Oil and gas are limited in their availability and are becoming increasingly more expensive, which is why more and more private individuals, commercial enterprises and local authorities are turning toward renewable fuels. Wood chips are particularly favoured, and CO2 neutral heating systems based on this renewable fuel source are technically fully developed and are in great demand. This is your opportunity.

Become a regional energy supplier for renewable fuels using the AHWI chipper - the demand for wood chips is continually rising, and this energy source is right on your doorstep. Almost all vegetable matter can be converted to wood chips: logs, residual wood, waste wood, timber slabs, roadside greenery, or even wood obtained from building site clearance. In this manner, you can convert organic material, which has hardly any other use, into biomass for energy production – a new source of profit.

Wood chips to suit the customer’s taste

The quality of the produced wood chip is the prime concern of the customer. For the heating system being operated with this fuel source to be trouble-free, the fuel itself must be of uniform size and contain very few fine particles. Since May 2005 wood chips have been subjected to the preliminary European CEN/TS 14961 standard, which defines the parameters and categories for moisture content, ash content, particle size distribution, bulk density (in kg/m³ loose), nitrogen content, chlorine content and the net energy content (lower heating value (LHV)) as MJ/kg or kWh/m³ of the loose wood chip as a bio fuel.   

The quality of the wood chip is recognizable by these four basic characteristics:

1. The angular shape of the wood chip
2. A low proportion of green content (10% to 15%)
3. A low moisture content (< 20%)
4. The wood chip is very coarse, and the quantity of fine particles is very low  

If these four characteristics are satisfied, then it can be assumed that the resulting wood chip possesses a high calorific value. This calorific value also depends on the type of wood being used, but a rule-of-thumb suggests it should be between 3.5 kWh and 4 kWh per kilogram of dry wood with a moisture content of 20%. 

Wood chips? In an instant!

You do not even have to be put off by customers who are impatient: using the AHWI chipper you can produce up to 200 m³ of wood chips in an hour to replenish empty boiler rooms. A single cubic metre (m³), depending on its quality, is equivalent to approx. 330 kg of wood chip – which represents the calorific equivalent of 100 litres of heating oil!
