This study was conducted in Ziway - Hawassa milk shade, found in Oromia administrative region, Ethiopia with the objective to design suitable business models through quantifying greenhouse gas (GHG) emissions from smallholder milk producers. Five districts (Shashemane, Arsi - Negelle, Kofelle, Adami …

The growing appetite of cities is one of the greatest future challenges. There is no set menu for meeting this appetite, but a trend is observed in which city authorities focus on region-based food provision. Regionalism is motivated by the importance of increased self-reliance. Besides, regional food …

The reduction of water and energy consumption are two of the main focuses of action of the cheese companies with the aim of minimising their environmental impact. The research team of the Van Hall Larenstein University of Applied Sciences dairy research team is working on new possibilities for the cheese …

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, …

Wind and solar power generation will continue to grow in the energy supply of the future, but its inherent variability (intermittency) requires appropriate energy systems for storing and using power. Storage of possibly temporary excess of power as methane from hydrogen gas and carbon dioxide is a promising …

With sufficient electrical energy CO2 from the atmosphere, combined with water, can be converted to hydrocarbons. The first step in converting CO2 into a carbon based fuel is the dissociation of CO2 into CO and O. DIFFER explores the possibilities of this process by using a microwave plasma. This project …

In recent years, the recognition of the importance of ecosystem services provided by peatlands has become increasingly topical (Clarke, 2006). It is now known that peatland degradation and loss of habitat has large negative impacts, particularly with regards the loss of the habitats natural carbon sink …

Total organic carbon (TOC) is often found in natural water sources, and also may come from (chemical) water treatment processes or from sewage. It may react with disinfectants to produce DBPs (disinfection by-products), which are harmful to water systems and public health. Besides, in industrial systems …

Power to methane provides a solution to a couple of two problems: unbalanced production and demand of wind plus solar power electricity and the low methane content of biogas by storing electricity via hydrogen into methane gas using carbon dioxide from biogas and methanogenic bacteria. The four-year …

Wind and solar power generation will continue to grow in the energy mix of the future, but its inherent variability (intermittency) requires energy systems for storing electricity. Storage of electricity as methane from (bio)hydrogen gas and carbon dioxide is considered an interesting option. The surplus …
