A big problem is the scaling of machinery to the scope of the project. On the other hand using a relatively small machine like this to process large amounts of materials is extremely time consuming, noisy and not conducive to a pleasant working atmosphere. With the urgent need to remove as much of the organic fraction as possible from landfill sites, it makes sense for Councils to provide a variety of options including a mobile shredder service, to those people who wish to compost their own communities materials. The benefits of having a much larger machine with an operator. Groups do not have to be trained in the use of a shredder.
Volunteers can devote their time to making compost.
The machine is only running for a relatively short time as it processes materials far more quickly and efficiently. The group does not have to insure the machine. Much larger amounts to compost can be contemplated with the removal of this most demanding task, Potential shredder accidents and costly claims and settlements will be avoided. The disadvantages of a larger machine. You have to have sufficiently large amounts of' materials to merit having a larger machine visit.
