Due to the exhaustion and increased pressure regarding the environmental and political aspects of fossil fuels, the industrial focus has switched towards renewable energy resources. Lignocellulosic biowaste can come from several sources, such as industrial waste, agricultural waste, forestry waste, and …

Agricultural by-products, that is primary residue, industrial by-products and animal manure, are an important source of nutrients and carbon for maintaining soil quality and crop production but can also be valorised through treatment pathways such as fermentation, incineration or a combination of these …

Dutch dairy farms feel an increasing need to improve grassland production and grassutilization while at the same time reducing the environmental impact because of sustainability goals, legislation on manure management and recent intended policies.

Dutch dairy farms feel an increasing need to improve grassland production and grassutilization while at the same time reducing the environmental impact because of sustainability goals, legislation on manure management and recent intended policies.

The 'AgroCycle' project investigates whether a cooperation of farms can become self-sufficient in energy and fertilization by using manure and organic waste streams for the production of energy, green fuel and green fertilizers by means of anaerobic digestion (AD). In the project, the project partners …

This study was conducted to investigate dairy farming practices and gross margin at smallholder dairy farmer level to design a business model for scaling up climate-smart dairy in Ziway-Hawassa milk shed. 80 sample dairy farmers from five districts (which then categorised as urban and peri-urban dairy …

The dairy sector in the Netherlands aims for a 30% increase in efficiency and 30% carbon dioxide emission reduction compared to the reference year of 1990, and a 20% share of renewable energy, all by the year 2020. Anaerobic Digestion (AD) can play a substantial role in achieving these aims. However, …

Duurzaamheidsbalans: verschillende onderzoeksrapporten laten zien dat Europese grondstoffen voor eiwit in veevoer milieuvriendelijker zijn dan soja uit Zuid-Amerika. Het is daarom vanuit milieu-oogpunt wenselijk om meer regionaal geteeld eiwitrijk veevoer te gebruiken in Nederland. Ketenaanpak: De Raad …

The energy efficiency and sustainability of an anaerobic green gas production pathway was evaluated, taking into account five biomass feedstocks, optimization of the green gas production pathway, replacement of current waste management pathways by mitigation, and transport of the feedstocks. Sustainability …

Energy efficiency, greenhouse gas reduction and cost price of a green gas supply chain were evaluated. This supply chain is based on co-digestion of dairy cattle manure and maize, biogas upgrading and injection into a distribution gas grid. A defined reference scenario reflects the current state of practice, …
