Germany-headed Steinmüller Babcock Environment GmbH, part of the Japanese company Nippon Steel & Sumikin Engineering Co., Ltd has announced that has won the contract for the construction of a waste treatment centre in San Sebastian, the capital of the province of Gipuzkoa in Basque, northern Spain.

The contracting authority is a Spanish project company led by Urbaser S.A. and has been commissioned by the local waste collector Gipuzkoako Hondakinen Kudeaketa SA to finance, construct and operate the waste treatment centre estimated to be completed in 2019.

The total project value including financing and 32-year operation is about EUR 770 million of which the waste treatment centre is around EUR 217 million.

Scope of supply

As the leader of the general contractor consortium, Steinmüller Babcock Environment will coordinate the planning, design, procurement, erection and commissioning of the complete complex and will erect the turnkey thermal waste treatment plant.

The concept of the waste treatment plant includes a mechanical-biological treatment (MBT) stage as well as two thermal waste treatment lines with a combined annual capacity of 200 000 tonnes of municipal waste. The energy generated is enough to provide electrical power to more than 45 000 households.

The plant will have a three-stage flue gas cleaning concept. In the first stage, sulphur dioxide (SO2) and other acidic gases are separated by means of a dry sorption process based on bicarbonate. A second stage eliminates nitrogen oxides (NOx) by the use of SCR catalysts. The third stage reduces the remaining acidic pollutants as well as dioxins and furans to a minimum via a lime hydrate-based sorption process.
