Sustainability assessment of the CO2 methanation value chain: environmental impacts and socio-economic drivers and barriers
This project aims at evaluating the sustainability of the joint project’s “Reduction and reuse of CO2” value chain, i.e. the carbon dioxide methanation value chain – from the production of hydrogen through photoelectrochemical (PEC) water splitting (partner project 2), through the methanation of carbon dioxide from ...
Life holds temptations ready, which make each one of us to be carried away to a greater or lesser sin. But what are the truly ecologically relevant sins, what are they doing, and what can each individual do to avoid them and thus contribute to a more sustainable society? The "Ökobeichtstuhl" is an innovative ...
Life cycle assessment of Swiss wine from conventional and organic farming
The consumption of food and beverages causes more than a quarter of an average person’s environmental impact in Switzerland. Apart from meat, fish and dairy products, beverage and semiluxury food – especially spirits and coffee – contribute to a significant share. Over the entire life cycle of wine – from the ...
PV2050: Sustainability, market deployment and interaction to the grid – the impacts of advanced PV solutions
The opportunities for photovoltaic (PV) solar energy conversion to support the requested transition for the realization of the Energy Strategy 2050 are widely recognized. However, if PV is to make a significant contribution to satisfy global energy requirements, issues of sustainability need to be addressed with ...
LCA of peat, alternative substrates and growing media
Due to its soil improving properties peat is regarded as an ideal component of growing media. However, peat cutting has a high environmental impact. In Switzerland, the extraction of peat is prohibited since 1987, but 130’000 tons of peat are imported every year. To reduce peat consumption, alternative substrates ...
Renewable Methene for Transport and Mobility
Power to gas allows using excess renewable electricity to produce Hydrogen and to transform it to renewable methane. Methane can be used to drive natural gas vehicles. The processes described use building blocks made of existing technologies, link the grids for electricity and natural gas and make large existing ...
Life Cycle Assessment of Wind Power
Current life cycle assessments are an essential basis for a scientific and comprehensive comparison of the environmental impact of various power generation technologies. The low environmental impact (e. g. carbon footprint per kWh) is an important argument for the expansion of wind energy in Switzerland. However, ...
Applying Life Cycle Assessment for the mitigation of environmental impacts South African agrifood products
The project contributed to the important global question of how to reduce environmental impacts from food production, with a focus on South African food value chains. The Swiss and South African project team joined forces to ensure basic data collection for South African maize, dairy and fruit production, life cycle ...
ProPAT – Robust and affordable process control technologies for improving standards and optimising industrial operations
The Process Industries require a high degree of automation, monitoring, and advanced simulation and control for their often complex manufacturing processes and operations. Emphasis is on continuous or batch production, mixing, reaction and separation of materials of higher value. Indeed, increased globalisation ...
Global Greenhouse Impact Model
The carbon footprint of foodstuffs is a key factor for sustainable development of the food sector. One of the major factors contributing to the carbon footprint of foodstuffs is the heating of greenhouses. The required quantity of heating is highly variable depending on production season and local climatic ...
ZHAW Agri-food Database
The Agrifood database is collection of life cycle inventory data for agricultural and food products. This database can be used to analyse the environmental impacts of processes in the agricultural and food value chain and to determine the corresponding environmental hotspots. The Agrifood database includes life ...
