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.

Nynas experts lecture at KTH

Nynas traditionally maintains a close partnership with universities and higher education institutions. An illustrative example of this is the lecture on the oil industry held for students at KTH Royal Institute of Technology in Stockholm.

Research collaborations in focus

Complex research projects with industry and research institutes/universities highly contribute to knowledge build up not only for the future product development but also allow to identify the benefits of our products and their performance in the use phase.  At the same time, it contributes to the high level of specialist knowledge at Nynas.

Passion for Cold Recycling Projects

Whilst growth in cold asphalt using foam bitumen is on the increase, a select few are turning their focus onto emulsion. One of them is Roadways, a UK-based highways construction company that recently carried out resurfacing work in East Sussex. Roadways used Nymuls CP 50 in a cold asphalt binder course made with 100% recycled aggregates, which resulted in 40% less carbon dioxide emissions.
