Biosolids composting at the Borough of Mechanicsburg, PA WWTP
The Borough of Mechanicsburg, located in central Pennsylvania, was experiencing challenges in finding sufficient agricultural fields to continue the beneficial use of their anaerobically digested liquid wastewater treatment plant Class B biosolids. At the time, the only alternative available was dewatering and going to landfill, which is significantly more expensive. Due to environmental ...

Introduction of composted digestates in agriculture
Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...

Optimization of the thermophilic anaerobic co-digestion of pig manure, agriculture waste and inorganic additive through specific methanogenic activity
The anaerobic co-digestion of three wastes (manure, rice straw and clay residue, an inorganic additive) at different concentration levels and their interactive effects on methanogenic activity were investigated in this work at thermophilic conditions in order to enhance hydrolytic activity and methane production. A central composite design and the response surface methodology were applied for ...

The CAMBI process and agriculture, a sustainable solution?
Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...

Valorising Agri-Waste – Agriculture produces an unsustainable amount of waste, so how does the bioeconomy let us derive value from it?
For every kilogram of “usable” crop produced in agriculture, between 1 and 2.5 kilograms of residue is also produced. Of course, some of this residue must remain in the field or be used elsewhere on the farm in order to maintain a healthy ecosystem, but that which isn’t used thus is an unavoidable waste. Minimising waste is one of the central tenets of sustainability: the waste ...

The Effect of COVID-19 ‘Panic Buying’ on Food Supply Chains and the Requirement for Gas Sensing
IntroductionCOVID-19 concerns around the world have sparked widespread panic buying and empty supermarket shelves. Large-scale lock-downs to contain the outbreak have further hurt the supply of manpower and disrupted supply chains in the agricultural industry.The United Nations’ Food and Agriculture Organization have said that the world risks a ‘looming food crisis’ if we do not take fast ...
