Life cycle based water assessment of a hand dishwashing product: Opportunities and limitations
It is only recent that life‐cycle based indicators have been used to evaluate products from a water use impact perspective. The applicability of some of these methods has been primarily demonstrated on agricultural materials or products, since irrigation requirements in food production can be water intensive. In view of an increasing interest on life‐cycle based water indicators from different ...

Water Footprint and Life Cycle Assessment as approaches to assess potential impacts of products on water consumption. Key learning points from pilot studies on tea and margarine
Water accounting and environmental impact assessment across the product’s life cycle is gaining prominence. This paper presents two case studies of applying the Life Cycle Assessment (LCA) and Water Footprint (WF) approaches to tea and margarine. The WF, excluding grey water, of a carton of 50 g tea is 294 L green water and 10 L blue water, and that of a 500 g tub of margarine is 553 L ...

Bio-plastic (poly-hydroxy-alkanoate) production from municipal sewage sludge in the Netherlands: a technology push or a demand driven process?
Valorisation of components from municipal ‘waste’ water and sewage sludge gets more and more attention in order to come to a circular economy by developing an efficient ‘waste’ to value concept. On behalf of the transition team ‘Grondstoffenfabriek’ (‘Resource factory’) a preliminary research was performed for all the Dutch water boards to assess the technical and economical feasibility of ...

Unlocking the power of water: Seven interventions to transform food systems
On World Food Day, a look at the role of water for more resilient and sustainable food systems. Water is essential for all life on earth and is central to the healthy functioning and sustainability of the Earth’s ecosystems. But what about the profound impact of water on our food systems? The Food and Agriculture Organization highlights that 3.2 billion people already live in regions ...

Aquifer recharge with reclaimed water: life-cycle assessment of hybrid concepts for non-potable reuse
Aquifer recharge with reclaimed water is a promising means to store and supply on demand reclaimed water of high quality for further non-potable reuse. The reuse applications may include indirect agricultural or landscape irrigation, saltwater intrusion barriers, subsidence mitigation or aquifer replenishment. As an alternative to high-pressure or double-membrane systems, hybrid schemes ...

Understanding the impacts of allocation approaches during process‐based life cycle assessment of water treatment chemicals
Chemicals are an important component of advanced water treatment operations not only in terms of economics, but also from an environmental standpoint. Tools such as life cycle assessment (LCA) are useful for estimating the environmental impacts of water treatment operations. At the same time, LCA analysts must manage several fundamental and as yet unresolved methodological challenges, one of ...

What is the water footprint?
The water footprint is an essential tool to understand the impacts human have on this essential yet finite resource. Water has become increasingly vulnerable as a result of climate change, population growth and growing pressure on this resource. In this context of global scarcity, there is an urgent need to calculate the water footprint as it is a tool that enables us to understand where, when ...

Life cycle assessment of drinking water installations: existing studies and analysis of discrepancies
This paper gives an overview of existing Life Cycle Assessment (LCA) studies of drinking water installations in Europe. The characteristics and results of the two most widely known and used studies, the VENOB study and the CREM study, are described in detail. Readers get a thorough understanding of the key issues and parameters of life cycle studies in this field. As the study results diverge ...

Life-cycle assessment of common water main materials in water distribution networks
This paper examines the economy-wide environmental impacts linked to the manufacturing of PVC and ductile iron (DI) pipes, steel tanks, and to the generation of electricity for pumping in water distribution network optimization. The non-dominated sorting genetic algorithm (NSGA-II) is used to generate Pareto-optimal solutions of the benchmark ‘Anytown’ network expansion problem. Selected ...

Life cycle assessment of three water systems in Copenhagen - a management tool of the future
Environmental life-cycle assessment (LCA) was applied to evaluate three different water systems of the water sector in Copenhagen, Denmark, including technologies within water supply, facilities recycling water and treatment of sewer overflow. In these three water systems LCA was used to evaluate the environmental impacts of each of the processes involved. The overall conclusion was that LCA is ...

The use of life cycle assessment for evaluating the sustainability of the Amsterdam water cycle
Waternet, the water cycle company of Amsterdam and surrounding areas, uses the life cycle assessment (LCA) method to evaluate the environmental impact of investment decisions and to determine the potential reduction of direct and indirect greenhouse gas (GHG) emissions of different alternatives. This approach enables Waternet to fulfil its corporate objective to improve sustainability and to ...

Sustainability assessment of urban water planning using a multi-criteria analytical tool – a case study in Ningbo, China
Sustainable urban water infrastructure planning has become one of the major concerns when facing the growing urbanization pace and challenges in China. The paper aims to integrate the modern decision support tools in urban water supply system (WSS) planning and programing. A case study of Ningbo, China is presented to assess the cost-effectiveness and sustainability of the selected WSS. A ...
