Special fabrics are often used in civil engineering works, including highways, to make soil stronger Geosynthetics have been used in roadway construction for thousands of years with natural materials being mixed with soil to improve quality and stability. While today's products are much more sophisticated, the principles are the same. For example, when used with soil, geotextiles (permeable fabrics) can filter, separate, reinforce, protect, or drain, and they are often made from polypropylene or polyester,

The Renault Nissan Alliance, PSA Peugeot Citroën and Mitsubishi Motors have decided to develop and promote the technical reference for compliance of public recharging equipment for electric vehicles in Europe, based on the existing conformity brand 'EV Ready', originally launched by Renault and Schneider Electric.EV Rready aims at guaranteeing interoperability between the charging infrastructure and electric and rechargeable hybrid vehicles across Europe by means of a uniform scheme which is intended to cov

UK government emissions data shows that buses outside of London emit an average of 221g/km CO2e (CO2 equivalent) per passenger km compared to a small petrol car (201g/km), a small diesel car (172g/km) and a medium diesel car (215g/km). A car containing two people would obviously halve these figures. London buses, because of their higher average occupancy, fare better at 102g/km.

The BICES 2011 construction equipment exhibition close to Chinese capital Beijing proved a major draw for attendees.
