Creating renewable plastics that don't cost the Earth

Imagine a future where packaging is made entirely from waste material and biodegrades to harmless by-products. Or where your home's cavity wall insulation foam is made from captured CO2 emissions. Or where construction materials, vehicle components and engineering plastics are sophisticated biological composites comprised of tough cellulose fibres embedded in naturally derived polymers.

Limestone powder enhances performance of 'green' concrete

The promising laboratory results suggest a path to greatly increasing the use of fly ash in concrete, leading to sizable reductions in greenhouse gas emissions, energy use, construction costs and landfill volumes. Global production of cement for concrete accounts for 5 to 8 percent of human-caused greenhouse gas emissions.

Modular battery concept for short-distance traffic

Electric mobility may be economically efficient today. Battery-based electric drives can be applied efficiently in urban buses, for instance. Frequent acceleration and slow-down processes as well as a high utilization rate in short-distance traffic make their use profitable even when considering current battery costs. At the IAA International Motor Show in Frankfurt, Karlsruhe Institute of Technology (KIT) will present an e-city bus demonstrator to illustrate the concept.
