Dominance of chemical agriculture from last few decades has deteriorated the soil health and created problem of disposal of agricultural waste in rural areas. It is important to maintain environmental and agricultural sustainability without reducing productivity. Vermiculture technology has been considered as a sound and viable option to regenerate the soil health through recycling the agricult...

A biotechnology for aerobic conversion of food waste into organic fertilizer under controlled aeration, stirring, pH and temperature at 55-65 degrees C, is proposed. To maintain neutral pH at the beginning of the bioconversion 5% CaCO3 was added to the total solids of the food waste. The addition of 20% horticultural waste compost as a bulking agent to the food wastes (w.w./w.w.), improved the ...

Background In 2012 the Coordination Program Network of European Transnational Research in Organic Food and Farming Systems called for research on sustainable and efficient management of phosphorus and use of secondary fertilizers within organic agriculture. Recognizing that the mineral resources of natural phosphorous world-wide (suitable for extraction) are expected to meet requirements for th...

1. Sustainable development Today, the concept of sustainability significantly affects our life and economic activities. In 1987, the Bruntland Commission stated: “Humanity has the possibility of making development sustainable, i.e. ensuring that the needs of the present are met without compromising the ability of future generations to meet their own needs” (World Commission for environment and ...

A reduction in the loss and waste of human food is a global issue for addressing poverty and hunger in poorer nations, and for reducing the environmental footprint of the agriculture sector. An emerging issue, however, is that food wasted by humans is often accessible to wildlife, affecting wildlife ecology and behaviour, as well as ecological processes and community dynamics. Here we highlight...

The increase in agricultural production and food quality has forced the growing use of plastics various activities. plastic wastes are partially recycled or outside Portugal; nevertheless, contaminated sent to landfill. It is crucial consider new models for their valorization at a regional level from circular economy perspective. In scope Placarvões project, study was elaborated, which included...

UA-Magazine he use of municipal wastewater to fertilize ponds began in Kolkata in the thirty’s, and it is now perhaps the largest wastewater fed aquaculture system in the world (Nair, 1944; Jhingran, 1991). Kolkata is a metropolis of 14 million inhabitants. The Kolkata periurban area especially where wastewater fish farming is practiced supports the livelihood of a large number of people throug...

Sewage sludge was used as fertilizer in agriculture in Switzerland since the begin ning of modern waste water treatment. During the last 40 years several difficulties arose with the agricultural use. The problems with pathogenic germs could be solved with a prepasteurisation. The contamination with heavy metals was reduced during the years but remained a cause for concern. The fear of mad cow d...
