Sustainable cities

In many contexts, sustainability has become a buzz word that is hard to define and often lacks specific meaning. At Envac, when we want to define how our system contribute to a sustainable city, we use the definition made by the Brundtland Commission. It is based on environmental, social and economic perspectives.

The environmental perspective

Our solutions eliminate the local environmental impact caused by traditional waste collection vehicles. In other words, they reduce carbon dioxide emissions. Large waste collection vehicles, driving and reversing along inner city streets that are often narrow and congested, become thing of the past. We also drastically reduce the environmental impact of vehicles driving to the processing plants by only transporting containers that are completely filled with compacted waste.

As we move the transport of large amounts of waste under ground, we create an important improvement of the waste collection at the same time as we improve the urban environment, the living environment and the working environment.

We only use electricity to operate our facilities. Every year, we invest substantial development resources to reduce our energy consumption and also to find ways of improving the technology to further encourage recycling. Our systems facilitate waste separation at source, which is internationally accepted nowadays as the only effective solution for reusing and recycling waste materials.

The social perspective

Numerous surveys show that residents living in Envac system areas are more satisfied with the system of waste collection than those with traditional collection systems. This is hardly surprising, since the heavy traffic and waste bins have been eliminated. The chutes don’t fill up, even during holiday periods or extremely bad weather, because the system is fully-automated and sucks the waste to a central collection point without the need for human intervention. Obviously, this leads to better hygienic conditions and reduces the amount of noise and rubbish on the streets, thereby enhancing the attractiveness of the neighbourhood and the quality of life for its residents.

The economical perspective

If you compare the lifetime costs of our systems with traditional collection methods, you’ll see that in most cases the cost is lower for our systems in medium-sized and large towns where population densities are relatively high. This assumes that the residential areas and city centres are planned and built with our technology right from the start to assure coordinated installation with other infrastructural facilities such as water, sewage, electricity and district heating. Furthermore, this makes it possible to build more compact communities and save space inside the buildings. Although the initial outlay is naturally more expensive than for traditional waste collection, the running and maintenance costs are considerably lower and thus compensate for the high investment.
