Energy Management

The city of Yogyakarta is a centre for wood craft and furniture manufacture, and the tannery has put this to good use by recently installing a wood-burning hot water plant. This consumes approximately 6m3 (0.5 ton/m3) of off-cuts from mango, coconut, jack-fruit and bamboo trees that have no other use, and is the sole source of heat for wet processing and drying. This has saved approximately 400 litres of heavy fuel oil per day.

Waste wood from furniture manufacture is used as fuel. This saves approximately 400 litres of heavy fuel oil each day.
Energy savings are made as natural air drying is used as far as possible, although this does need additional support from heating cells. The building used for sorting, trimming and grading pickled and wet blue skins is kept cool by the installation of woven bamboo frames on all of the walls and ceiling.

 

 

The two milling drums in the finishing department are made locally. They are mounted on a steel framework so that they can be readily repositioned.
As the factory is subject to power cuts, a generator is installed on site. This has been mounted on a rubber bed to minimise noise and vibration, and is capable of providing the energy needs of the whole tannery if required. At the moment work is taking place on renewing the power cables.
