Biogas from human waste, safely obtained under controlled circumstances using innovative technologies, is a potential fuel source great enough in theory to generate electricity for up to 138 million households - the number of households in Indonesia, Brazil, and Ethiopia combined.
According to the United Nations Environmental Programme, an estimated 50 million tons of electronic waste are generated around the world every year. What's more, the metal deposits found in many types of e-waste can be 40 to 50 times richer than the raw ore extracted from mines. One ton of gold ore, for example, yields 5 grams of gold, on average. However, approximately 150 grams of gold can be found in one ton of phone circuitry.
Wastewater treatment plants can benefit from a new chemical oxygen demand (COD) analyzer that will provide plant engineers with another tool to monitor water quality and prevent environmental contamination.
Fish farming is the largest source of phosphorus emissions in Norway, generating about 9,000 tonnes a year. Finding ways to reuse the waste from the fish farming industry could cut consumption of this important and increasingly scarce resource.
Estimated electricity production from the total waste generated in Africa could reach 122.2 TWh in 2025, or more than 20% of the electricity consumed in 2010 at continental level (661.5TWh), according to a JRC co-authored study which analysed the potential of urban solid waste for Africa’s electricity needs.
The MBR REMEB project arises from research in the field of low cost recycled ceramic membranes to develop a water treatment that combines biological treatment with membrane technology, specifically in a membrane bioreactor (MBR).
As England gets set to start paying for plastic bags, researchers at The Open University (OU) are making inroads into developing alternative biodegradable materials that could potentially replace fossil fuel derived polyethylene single-use carrier bags in the future.
Consider the plastic foam cup. Every year, Americans throw away 2.5 billion of them. And yet, that waste is just a fraction of the 33 million tons of plastic Americans discard every year. Less than 10 percent of that total gets recycled, and the remainder presents challenges ranging from water contamination to animal poisoning.
Researchers at Cardiff University have devised a way of increasing the yield of biodiesel by using the waste left over from its production process.
Northrop Grumman Corporation announced that its Palmdale Aircraft Integration Center of Excellence (PAI CoE), within its Aerospace Systems sector, received the Silver level Zero Waste certification from the U.S. Zero Waste Business Council (USZWBC). This award is significant in that the site is the first aerospace production and manufacturing facility in the U.S. to receive this honor.
