Europe’s most modern Waste Recycling Facility – Newsletter “International Vienna” 03/2008

The first priority of Vienna’s waste management system is the prevention of waste, in accordance with the motto “The best waste is that which is not created”. Waste which cannot be prevented is separated, collected and, if possible, recycled following a sophisticated waste separation and recycling scheme. For this purpose, Vienna provides about 400,000 waste containers for residual waste, waste paper, waste glass or organic waste, 19 waste collection sites, 53 hazardous household waste collection sites and much more. Municipal waste which cannot be recycled is used to produce valuable energy – for example at the recently opened Pfaffenau waste incineration facility.

High-tech to protect people and the environment
By undergoing a large-scale environmental impact assessment procedure, which ensured greatest possible transparency for the citizens of Simmering and Vienna, the Pfaffenau waste incineration facility wanted to prove its compliance with the strictest environmental laws in the European U nion – and passed the test with flying colours. The facility not only complies with the EU’s stringent emission limits, but emissions from daily operations are two to ten times below the established limits. Thus, a four-stage flue gas purification system guarantees lowest emission values, which are 90 percent below the allowed limit for dust and as much as 95 percent below the limit for SO2. As a result of the cogeneration system, the facility achieves an outstanding efficiency rate of 76 percent.

The Pfaffenau waste incineration facility
Every day about 200 waste collection vehicles of the Municipal Department 48 – Waste Management, Street Cleaning and Vehicle Fleet (MA 48) deliver the collected residual waste. Cranes transport the waste from the receiving bunker, which has a capacity of approximately 18.000 cubic metre, to the feeding hoppers of the two incineration grates. 32 tonnes of residual waste are burned per hour at a temperature of about 850 degrees centigrade.

In the waste heat boilers the heat capacity of the flue gases produced during the incineration is used to generate steam. This steam, which has a pressure of 40 bar and a temperature of 400 degrees centigrade, is conducted into a steam turbine. In the generator, the energy transmitted to the turbine rotor is transformed into electrical current. The steam left over after the turbine is conducted into district heating heat transformers. The heat released during the condensation process taking place in these transformers is emitted to the directly connected district heating network.

A four-stage flue gas purification facility – consisting of an electrical filter, a two-stage wet cleaning system, an active coke filter and a denitrification system – meets highest environmental standards. Owing to these state-of-the-art filter systems, the facility achieves lowest emission values. Boiler and filter ash is temporarily stored in ash silos and finally deposited together with the slag at the Rautenweg landfill site.

At the end of the incineration grates a magnetic separator separates and disposes or recycles slag and scrap metal. The generated sewage is cleaned and channelled into the nearby main sewage treatment plant.

Simmering Environmental Centre attracting numerous visitors
Since its opening in autumn 2007, the biogas facility at the Simmering Environmental Centre has already been visited by numerous delegations from Austria and abroad, who wanted to gain an insight into the state-of-the-art technology and design of the facility. In addition to the new biogas facility, the Simmering Environmental Centre also comprises Vienna’s main sewage treatment plant, which was opened in 2005. With the opening of the Pfaffenau waste incineration facility this year the Environmental Centre was completed. It now has in full operation three of the world’s most modern facilities for the treatment of waste and wastewater, which make an enormous contribution to environmental protection in Vienna and far beyond.

But this article does not prove anything and does not tell you that there are more advanced Plants that actually do not require the waste to be separated beforehand! It is more reliable, because when humans do it, they can put one ‘not belonging’ piece in the lot that will contaminate the whole container, for instance.

The article would make more sense if they mentioned Güssing (Proofing).

Anyways, where can I buy these advanced plants, so I give them to lazy neighbours & recommend/write to EADS + NASA that we can plant them on Mars; thus ensure that humans do not contaminate the whole mars containers, as we have to relocate there or some other planet, sooner or laters.
