Biogas plays an important role in many future renewable energy scenarios as a source of storable and easily extracted form of renewable energy. However, there remains uncertainty as to which sources of biomass can provide a net energy gain while being harvested in a sustainable, ecologically friendly manner. This study will focus on the utilization of common, naturally occurring grass species which are cut during landscape management and typically treated as a waste stream. This waste grass can be valorized through co-digestion with cow manure in a biogas production process. Through the construction of a biogas production model based on the methodology proposed by (Pierie, Moll, van Gemert, & Benders, 2012), a life cycle analysis (LCA) has been performed which determines the impacts and viability of using common grass in a digester to produce biogas. This model performs a material and energy flow analysis (MEFA) on the biogas production process and tracks several system indicators (or impact factors), including the process energy return on energy investment ((P)EROI), the ecological impact (measured in Eco Points), and the global warming potential (GWP, measured in terms of kg of CO2 equivalent). A case study was performed for the village of Hoogkerk in the north-east Netherlands, to determine the viability of producing a portion of the village’s energy requirements by biogas production using biomass waste streams (i.e. common grass and cow manure in a co-digestion process). This study concludes that biogas production from common grass can be an effective and sustainable source of energy, while reducing greenhouse gas emissions and negative environmental impacts when compared to alternate methods of energy production, such as biogas produced from maize and natural gas production.
I remember the last conversations my former colleague José and I had one year ago. At that time, we were working in a small art gallery owned and controlled by a private company. We were placed in different positions, but both of us felt trapped and enslaved by the system. José went to India many times to learn wisdom from the wise religious thinkers. After returning, he quit smoking and became a vegetarian. He now lives at the border between two small European countries.

This book is about you. Are you, as a customer, as an entrepreneur, as an individual, ready for the Internet and e-business? Do you see the possibilities and do you actually use these? Do you have an idea of where it will end? Did you ever list how the Internet changes your life as an entrepreneur? And, do you make the next move or do you let it all happen to you? About the fact that the Internet is much more than e-mail, shopping, chatting and searching. About how the Internet as a driver of e-business changes the set-up of your company or educational institution and maybe your very business in a very positive and still “e-secure” way: marketing & sales, operations, purchasing, recruitment & selection, e-HRM. We go through six related trends with you, without pretending to be complete.
The pipelines are buried structures. They move together with the soil during a seismic event. They are affected from ground motions. The project aims to find out the possible effects of Groningen earthquakes on pipelines of Loppersum and Slochteren.This project is devised for conducting an initial probe on the available data to see the possible actions that can be taken, initially on these two pilot villages, Loppersum and Slochteren, for detecting the potential relationship between the past damages and the seismic activity.Lifeline infrastructure, such as water mains and sewerage systems, covering our urbanised areas like a network, are most of the times, sensitive to seismic actions. This sensitivity can be in the form of extended damage during seismic events, or other collateral damages, such as what happened in Christchurch Earthquakes in 2011 in New Zealand when the sewerage system of the city was filled in with tonnes of sand due to liquefaction.Regular damage detection is one of key solutions for operational purposes. The earthquake mitigation, however, needs large scale risk studies with expected spatial distribution of damages for varying seismic hazard levels.
Façades have a high environmental and economic impact: they contribute 10-30% to GHG emissions and 30-40% of the building investment of new buildings [1]. Modern façades are highly optimized complex systems that consist of multiple components with varying life cycles [2]; however, many of the materials they employ are critical, and have a high CO2 footprint [3, 4]. New bio-composite facades products have emerged (a) whose mechanical properties are comparable to those of aluminum or glass fibre; (b) have a lower energy footprint; and (c) can fully or partially biodegrade [5]. Moreover, primary material sourcing from different waste streams can significantly lower the end products’ pricing. Still, their aesthetic qualities have not been sufficiently explored, so the scalability of their production remains limited. This project will develop specific combinations of bio-composites using food waste fillers and a biopolymer resin. Sheet samples will be made from these combinations and further tested against their mechanical properties, water resistance, aging and weathering. A Life Cycle Analysis will further consolidate the samples’ energy footprint. A new facade cladding tile product system with complex geometry using the overall best performing material composition will be designed and prototyped [17]. Emphasis will be given to the aesthetical properties of the tiles and their demountability. The system tiles will be further applied and tested at 1:1 scale, at The Green Village. During the project, an advisory board consisting of several companies within the building industry will be systematically consulted and their feedback will help the overall design process and their respective end products.
The population in rural areas in the northern provinces are aging in a much higher pace than in other parts of the Netherlands. Many young and higher educated citizens move out of these provinces. Quality of life in rural villages decreases likewise and the inhabitants that stay behind are more vulnerable, with lower income and educational levels. Recent decentralization policies put a larger burden on local constituencies to guarantee the quality of the living environment but a lot of them lack sufficient knowledge and capacity to tackle this complex issue.The initiators of this application have joined their knowledge and experience to put together a consortium with the aim to support these smaller constituencies in rural areas in the three northern provinces with a new and innovative methodology: the GO! approach. This approach was developed in the neigborhoods of Utrecht municipality and will be used for the first time in rural communities with a comparable size .This approach consists of the following steps:• First to identify possibilities to create a healthier living environment by analyzing available data on pollution, spatial layout and social cohesion.• To discuss the result of this analysis with local citizens and other local stakeholders in order to link the data with local experiences• To prioritize into major themes as a result of the combination of all this available information.• To link these major themes to combinations effective measures available from RIVM and international databases.• To present these combinations to the local government, their citizens and other local stakeholders in order to let them choose for an effective approach and inplemant it together in order to create a local healthier living environment.The GO! approach will provide local citizens and professionals with the necessary tools and knowledge to work jointly and effectively to realize a healthier living environment. The project partners that jointly started the consortium will put in effort during this first year to build and formalize the consortium and to make arrangements with several constituencies in the three northers provinces to formulate their own specific knowledge agenda as a basis for concrete project proposals in the second stage to be implemented with the support of the formalized consortium.
