CO2 emissions savings as high as 5.8 billion tonnes by 2050 WorldWide
Buildings are the biggest opportunity to reduce carbon for cities. A study by the International Energy Agency (IEA) shows that, if implemented globally, energy efficiency measures in the building sector could deliver CO2 emissions savings as high as 5.8 billion tonnes (Gt) by 2050, lowering greenhouse gas emissions by 83 percent below the business-as-usual scenario.
Most of these technologies are commercially available today and many of them deliver positive financial returns within relatively short payback periods. Read More
Wastewater is becoming one of the world’s greatest sustainable resources
Water reuse is becoming increasingly important for modern societies. Especially those based in arid regions. Examples include well-known sites such as Water Factory 21 in California’s Orange County Water District and the NEWater project in Singapore. Scientists and engineers are increasingly concerned about emerging contaminants in wastewater treatment plant effluent. Read More
The rising price of petroleum and increasing concerns about the environmental impact of chemical cleaners and strippers has sparked an interest in biobased solvents. Methyl soyate, a methyl ester derived from soybean oil, is the key ingredient in an eco-friendly mix. This low-cost, readily biodegradable alternative could replace some of the 460 million pounds of traditional chlorinated and petroleum solvents. Read More
The first 1,55 installations are operational in Tanzania and Kenya. By the end of 2014 that must be 5,000. SimGas starts trial runs in Rwanda and India. Within 5 years they expect to deliver in 10 African and Asian countries.
Like many subtropical regions, farmers in the Sub-Saharan – Africa – depend primarily on wood for energy.
Biogas is particularly well suited to meet household energy needs in Sub-Saharan Africa, while simultaneously improving both soil conditions and household sanitation.
These systems will spark a revolution in the biogas business in (sub)tropical regions by providing unique, off-the-shelf biogas solutions.
A recently published paper in Science today details how to create regenerating plastic objects that can self-repair damage that stretches more than an inch across. An object can be damaged over and over and still repair itself without seriously compromising its strength.
