Rotary Kiln Technologies

Our main focus is to provide rotary kiln based waste processing plants. Simply because this is the most versatile (in waste acceptance), the most reliable (in day to day operations and maintenance), the most technical straightforward (proven reliability on end quality and emissions) and with that the most effective solution.

Pyrolysis / Gasification

WK-TWT has built a 60.000 tons/year chemical waste gasification plant, now in operation for more than 15 years (which is rather unique on the planet) and knows – out of practice- the advantages and disadvantages of such a process. On specific application pyrolysis has major advantages over conventional incineration; making it a practical advisable solution. 60.000 tons/year hazardous chemical waste gasification plant

Fluidized Bed Technologies

WK-TWT has operated and improved fluidized bed technology for many years: similar to gasification/pyrolysis, fluidized bed can have specific advantages on dedicated waste streams. Although definitely not as versatile as rotary kiln technology, fluidized bed incineration does have its reason for living if applied to specific waste streams (generally speaking with well-defined properties).

Mercury Treatment Technologies

WK-TWT has successfully built and operated the first Mercury treatment facility in South East Asia, complying with all international standards; resulting in complete non-hazardous end products with typically < 5 mg Hg/kg. Typical Mercury removal efficiencies > 99.97 %! Most components manufactured, tested in Singapore, assembled in Thailand. 120 tons/year Hg treatment facility

Waste Storage And Transfer Technologies

To store and pump wastes is not “as easy as it looks” and greatly underestimated generally speaking in the engineering phase. Waste storage and pumping is a very specific and unique technology, at least if you want to do this in a reliable way. WK-TWT has the proven know-how to deal with your waste in a reliable way. The large pump concept provides a simple but reliable way to transfer wastes, up to pump discharge pressures of 120 bar (g) (= pumping line pressure). Pumps of this type are able to operate at a pumping rate of 30.000 tons/year of shredded metal waste and sludges (= 240.000 tons of waste through 1 single 700 mm bore pump) Large pump concept (having pumped more than 250.000 tons of shredded chemical waste)
