SUSTAINBLE DESIGN

 

Dutch municipalities are aiming to be purchasing 100% sustainably by 2015. InVra plus has been working on sustainable design for some years, which involves considering the burden placed on the environment. Various wooden bridges have been designed and built using accoya wood, for example. During the lifetime of the bridge three new trees can grow to maturity. Our sewer designs also stand out for their simplicity. Our aim is to use pump wells as little as possible and to have the water infiltrated or discharged to open water wherever possible. In areas with combined sewer systems we look into ways for disconnecting rainwater. We also lay down materials that require little maintenance. To stay completely up-to-date with the latest developments we invite suppliers to give a company presentation, and where possible InVra plus operates the Cradle to Cradle principle for new designs.

 

The Cradle to Cradle principle is a new way of looking at sustainable design, as published in a book by William McDonough and Michael Braungart 'Cradle-to-Cradle: Remaking the Way We Make Things'.

 

What is the cradle to cradle principle?

The essence of the Cradle to Cradle principle is found in the concept: waste is food. After being used in the one product, it should be possible to reuse materials in another. There must not be any loss of quality and all of the remnant products must be reusable or environmentally-neutral. That completes the circle... and waste is food.


Sustainable development is development in which the current generation meets its own needs without limiting the ability of the next generation to do the same. The Cradle to Cradle (C2C) principle goes beyond that and aims not only to meet our own needs but also to provide more options for future generations. The basic aim is to try to be good rather than less bad!


The three basic rules of the cradle to cradle principle

Waste = food
The sun is the energy source
Respect for Diversity

 

"Industry must protect and enrich eco systems - the biological metabolism of nature. At the same time it must maintain a safe, productive technical metabolism for high quality usage and the circulation of mineral, synthetic and other materials."
