This plant was designed as mass burn combustor capable of combusting
residential, commercial, and light industrial wastes.
The equipment is in excellent condition, a conclusion supported
by the evaluation of
an independent internationally recognized third party engineer.
Three other plants
developed using the same technologies continue to prove the value
of this technology. Key plant operating systems iclude a 7 MW Asea
Brown Boveria VAX Turbine and two Zurn
Boilers, a summary of major plant components could be provided.
The facilty was constructed at a cost in excess of $ 35 million.
The facility was closed
as a result of failed business decisions forcing the project into
financial bankruptcy. The plant operated for less than 5.000 hours. The
facility was meticulously
decommissioned to preserve the asset value and based on the espectation
of the lender that it would resume operations. Included with the equipment
are plans, specifications, as built drawings, operation manuals and detailed
Air Impact study conducted by the US Environmental Protection Agency which
confirms the integrity of the design of the
plant.

We are offering the plant "as/where is" for US$ 6.000.000,00,
reasonable offers will
be considered.
We could also provide our services of dismantling, packing, shipment
and erection
supervision for this plant.
Due to the vast trash quantities which have to be removed in many
areas a tonnage
fee/subsidy is given from the local government/municipality for
the clean combustion
of the trash. This makes the investment even more attractive.
