Manure and sewage can provide crops with more phosphorus than chemical fertilisers
Phosphorus in sewage and manure could be more available to crops than previously thought, suggests new research. The study found that some forms of sewage and manure treatment provided plants with more phosphorus than conventional inorganic fertilisers. Over the past 50 years, chemical fertilisers containing inorganic phosphorus have boosted crop yields and food production across the globe. ...

Thermophilic Co-composting of Human Wastes in Haiti
Sustainable Organic Integrated Livelihoods (SOIL) is an organization that has been working on ecological sanitation in Haiti since 2006 and, in 2009, developed the nation's first waste treatment site to treat human faeces using thermophilic co-composting. Since the earthquake in 2010, SOIL has developed a composting design that eliminates pathogens and creates a re-usable nutrient-rich compost. ...

Climate change and pollution threaten fishing catches
Warming of coastal areas due to climate change is already having an important impact on fishing catches in the North Atlantic, according to a new study. The study also suggests that rising levels of nitrogen pollution, due to run-off from farming and sewage disposal, will pose a serious threat to fisheries in the near future if left unchecked. At the World Summit on Sustainable Development in ...

Self Cleaning Irrigation Water Filters
The self-cleaning irrigation water filter uses the filter screen to directly intercept impurities in the water, removing suspended solids and particulate matter, reducing turbidity, purifying water quality, and decreasing system dirt, bacteria, algae, rust, etc. It also ensures the safety of agricultural irrigation water and the normal operation of irrigation systems. YUBO Filtration Equipment ...

Household compost as good for soil as conventional fertilisers, say EU researchers
Since 2005, conventional disposal of organic waste has been prohibited in Sweden. Instead, this waste is incinerated or separated at source, processed (composted or anaerobically digested) and recycled as fertiliser on crop land. A new study has investigated the use of organic waste from different sources as a fertiliser and found that residue from biogas production is an effective fertiliser. ...

Peristaltic technology aids in prevention of ‘feminised’ male fish
Chemically-disrupted water streams are causing a substantial increase of ‘intersex’ fish. Nicola Martin reports on how peristaltic technology is addressing the problem of water pollution through more effective treatment techniques.It’s the story that has become a national curiosity: male fish swimming in our rivers have begun spontaneously developing female characteristics. Research dating back ...

Desert plantations could help capture carbon
Planting trees in coastal deserts could capture carbon dioxide, reduce harsh desert temperatures, boost rainfall, revitalise soils and produce cheap biofuels, say scientists. Large-scale plantations of the hardy jatropha tree, Jatropha curcas, could help sequester carbon dioxide through a process known as 'carbon farming', according to a study based on data gathered in Mexico and Oman that was ...

Increased oestrogen pollution in European rivers could affect development of brown trout
Brown trout (Salmo trutta) embryos exposed to oestrogen during development hatched earlier, grew more slowly and had a lower heart rate than unexposed individuals, according to a recent Swiss study. These findings may indicate that oestrogen pollution in some European rivers is contributing to the decline of wild populations of such species. Endocrine disrupting compounds (EDCs) affect ...

Hormones in wastewater disrupt fish reproduction over generations
Synthetic oestrogens in wastewater from contraceptive pills can have effects on fish reproduction and survival that worsen over several generations, new research has found. The study suggests that some fish populations may not be able to recover from levels of oestrogen pollution found in many freshwater environments. Freshwater ecosystems are increasingly under threat from both climate change ...

Cleaning up the baltic sea with mussel power
Excess nutrients in seawater can cause eutrophication, a major environmental concern. Shellfish species such as mussels can 'soak up' some of these nutrients. A recent Swedish study examines the cost-effectiveness of mussel farming in the Baltic Sea as a method of reducing nutrient concentration and compares its potential with other methods of combating eutrophication. Eutrophication, caused by ...
