The stretch film and the net in which the bales are wrapped consist of polythene, which converts to carbon dioxide and water when incinerated. The plastic film is thin, only 25-30 µ and it constitutes only 0,1-0,2% of the total weight of the bale. A roll of stretch film weighs approximately 17 kg and is sufficient for approximately 18 bales.

The net is made of environmental friendly polythene. A roll of net weighs approximately 30 kg and is sufficient for approximately 100 bales.

The stretch film, although thin, is very tough. This ensures the hermetic enclosure of the material, which prevents the escape of litter as well as stops the degredation processes. The waste is compressed and wrapped with stretch film, into airtight bales. Without oxygen the processes of fermentation and degredation cannot start.

• No fermentation
  
• No soaking leaching
  
• Clean and tidy storage & handling
  
• Watertight storage also outdoor

Thanks to the lack of oxygen inside the round bale there is no fermentation occurring inside. Storage is therefore without risk of build-up of methane gas. Poisonous substances can not be leached, since the stretch film effectively restrain all water from penetrating inside the bale (provided that the bales aren't submerged in water).

A complete plant with press, bale wrapper and conveyors consumes no more than 10-20 kW/h. Which comes out as low as approximately 1-1,5 kW per finished bale.

The low energy consumption owes to the special patented construction of the press. The functions of the press is electro-hydraulically powered. The press chamber has rotating sides and the feeding mat rests on rollers with ball bearings.

All the movable parts of the press uses ball bearings and are in different ways dampened to keep the noise levels down as much as possible. 2 metres from the press the noise level is as low as 83dB.

Measurements were done on December 21st 1993 on the noise levels of the press according to Swedish Arbetarskyddsstyrelsen's specifications for machines and certain technical devices, AFS 1993:10. These measurements were done according to both "Maskindirektivet 89/392/EEC" as well as own methods, and it shows that the noise level does not exceed 85dB (A).

Instruments used
Integration Sound Level Meter B&K 2225.
Kalibrator B&K 4230.

Measuring location
The equivalent contiuing A-weighed sound pressure level was measured outdoors 1,6 metres above ground and 2 metres from the machine.

The equivalent sound pressure level Leq, around the machine, was 73dB (A) at idle.
