The green city

The countryside is moving into the city. A slight exaggeration maybe, but it is a fact that green walls and roofs are becoming increasingly common in the urban environment.

A roof covering of moss, sedum, herbs or grass not only makes a colourful addition to the concrete jungle, it also has a positive environmental impact.

As well as the plants absorbing rainwater that evaporates back into the atmosphere, green roofs also dampen the sound level, save energy, reduce the temperature and have air purifying properties. It is a fact that a 10 m2 roof surface of dry vegetation absorbs as much carbon dioxide as a tree.

And let’s not forget biodiversity. Green roofs attract bumblebees, butterflies and other valuable insects, not least bees that play a crucial role as pollinators for agriculture, gardens and flower meadows. Bituminous membranes are used in order to protect the construction from water and roots growing through the material.

The runway of the future ready for take-off at Arlanda

Paving a runway at an international airport is a massive challenge. Doing it sustainably is groundbreaking. In a new collaborative project, Nynas, Skanska and Swedavia have proved it can be done. By using recycled asphalt and Nynas’ innovative binder, Nypol RE, they cut 120 tonnes of carbon dioxide emissions — without compromising the toughest performance standards.

Nynas joins the United Nations Global Compact

Nynas has joined the United Nations Global Compact, the world’s largest corporate sustainability initiative. By doing so, the company strengthens its commitment to responsible business practices and to supporting the global transition towards a more sustainable society.

Making a Difference

The social dimension is an important part of Nynas’ overall sustainability work. One expression of this is the company’s encouragement of employee-led initiatives that support local communities.
