water footprint of paper

A: There are really good things about plastic bags—they produce less greenhouse gas, they use less water and they use far fewer chemicals compared to paper or cotton. The water footprint of a piece of beef depends on how it was produced, e.g. INTRODUCTION reshwater is … The previous practices showed that water footprint analysis was an effective tool to achieve sustainable utilization of water resources by guiding the development of water-saving technology and product. Water footprint (WF) is a multidimensional indicator that shows water consumption volumes by source and polluted volumes by type of pollution. As increasing freshwater scarcity [...] Read more. “Footprint” evaluations — ecological, carbon, or water — determine the amount of a resource needed to produce a unit of a good. This paper calculated the water footprints per ton and per cup of tea and coffee, as well as “virtual” water imports into the Netherlands for each beverage. Water footprints are composed of three separate calculations: 1 Blue Water Footprint: The amount of surface water and groundwater required (evaporated or used directly) to produce an item. Climate change and other stresses are limiting the availability of clean water and cheap energy. Feeding the cow makes up 99% of the water needed to produce beef! The efficient use of water is a key area of environmental responsibility in UPM, which employs around 24,500 people and has production plants in 16 countries. The green water footprint is the amount of precipitation that is stored in the soil and consumed by crops during the growing season by evapotranspiration. The decisions being made today regarding the management of water and energy resources will profoundly affect our economic and environmental future. Tetra Pak can argue that the trees from which the cartons are made come … Based on the study by Hoeckstra et al. Although 521 million MWh per By Bevan Griffiths-Sattenspiel and Wendy Wilson. composition of animal feed, origin of the feed ingredients. This amount is equivalent to 0.74 m3/tonne of average. 1.2 Carbon Footprint Many organizations and governments are looking for strategies to reduce emis-sions from greenhouse gases from anthropogenic origins, which are responsible for global warming (Kennedy et al. Drawing upon one paper mill's extensive water footprint assessment, considering the whole supply chain, one A4 sheet of uncoated paper may take between 2 to 13 litres of water to produce The water footprint of a paper product for the industrial stage is estimated as follows: WF p E R Pindustry [ ]=++ in which E is the evaporation in the production process (m3/ton), R the water contained in solid residuals (m 3/ton) … This paper calculated the water footprints per ton and per cup of tea and coffee, as well as “virtual” water imports into the Netherlands for each beverage. Water Footprint is an accounting tool which helps in determining the volume of fresh water consumed by an individual, group or city. To visualize the relationship between consumption of goods and freshwater use, Hoekstra (2003) introduced the water footprint (WF) concept which measures the freshwater appropriated to produce goods or services, expressed as a water volume per unit of product. It used the water footprint method for the quantification. For the average person this equates to a whopping 3496 litres of water ‘eaten’ per person, per day. As a comparison, the following numbers are reported for other sectors: Land use change (incl. The high variability of this number depends, of course, on the source of the wood (especially because forest evapotranspiration and wood yield vary from one region to … 2009, 2010). Here’s why this number is so high: It takes a lot of water to grow the plants which feed the cow. Pulp and paper mills contribute to air, water and land pollution and discarded paper and paperboard make up roughly 26% of solid municipal waste in landfillsites. The water footprint is used here as indicator of water consumption in the full production chain of sugar or ethanol production. The water footprint map accounts for current and future water intensity of cultivation and production by origin of inputs, water usage, and infrastructure in production, distribution, and sales (Exhibit 1). The water footprint of printing and writing paper is estimated to be between 300 and 2600 m3/ton (2-13 litres for an A4 sheet). Source: Water Footprint. According to the previously cited U.K. study, it takes three reuses of a paper bag to neutralize its environmental impact, relative to plastic. (I preface this post by saying I strongly support WFN’s mission and work for a water secure world, so this is a critique of methodology, not of WFN). A water footprint shines a light on what you don’t see: water use that occurs in each step of the production process of the goods you buy. 2. By combining the increasing trends in both water use and FP water production with the increasing FP water/water use ratios in some regions, we can see that the overall water footprint of hydraulic fracturing is increasing through time; more water is being used for hydraulic fracturing operations, while, at the same time, comparatively more FP water is being generated. A water footprint is an indicator that looks at both the direct and indirect water use of an individual, business, community, city or country.. The input products of bioplastics mostly come from food crops such as … When the water required for all the steps to make a smart phone is added up, the water footprint of the production of a single phone is an estimated 3,190 gallons.The Water Footprint of Everyday Paper and Plastic. [5] While manufacturing causes many issues like pollution and the reduction of natural resources like trees and water, the disposal of these towels is also an issue. Index Terms Water Footprint, Water Scarcity, -Agriculture . For walnuts, shelled or peeled, that figure is approximately 73.5 gallons per ounce. Paper. Unfortunately, manufacturers are unlikely to change their ways unless consumers demand accountability. This study discusses the environmental impacts assessment of wool scouring process based on the WF theory. Producing paper towels requires things like trees, chemicals, fuel, water, and electricity—contributing to millions of metric tons of CO2 annually. For example, it takes 22 gallons of water to make one pound of plastic. About 10 percent more energy is used to produce a paper bag versus a plastic one, and about 4 times as much water. By comparison, the paper napkin causes a mere 10 grams of greenhouse gas emissions and uses 0.3 liters of water use while the linen napkin causes 112 grams of greenhouse gas emissions … The water footprint of a … In contrast, paper bags must be made from fresh raw materials which translates to more deforestation and habitat damage. [From the Water Footprint Network website] People use lots of water for drinking, cooking and washing, but even more for producing things such as food, paper, cotton clothes, etc. Van Oel and Hoekstra (2012) made a first estimate of the water footprint of paper in the main pulp producing countries. Chiu and Wu (2013) estimated the water footprint of ethanol from wood residues from the southeast United States. Tian and Ke (2012) made estimates of the water footprint of lumber, panels, pulp and paper in China. This is equivalent to 477 Olympic size swimming pools or daily water use for 315,000 to 393,750 people (according to the U.S. Geological Survey, on average each person uses 80 to100 gallons of water … Facts about Paper and Paper Waste. WWF has launched a new voluntary rating tool for paper companies to report on their global ecological footprint. 93% of paper comes from trees. The paper suggests few ways by which Carbon and water Footprint can be reduced. The major part of the water footprint of a hamburger refers to the water needed to make the feed for the cow. The factors that affect water footprint are: 1. This paper aims to summarize the approaches of water footprinting with focus on the approaches suitable to assess water consumption of agricultural activities. (I preface this post by saying I strongly support WFN’s mission and work for a water secure world, so this is a critique of methodology, not of WFN). Tobacco has a water footprint smaller than global average based on the fact that in Pakistan tobacco is the crop whose yield exceeds the global average yields, so its high per unit area production translates into low water footprint. The number will likely fall in a range of 1/2 gallon and 8 gallons per sheet (A4 size). The exact amount depends on the sort and origin of the paper used for printing. As we speak, more than 199 tons of paper has already been produced (paper production in 15 seconds). natural resources. The Paper Company Environmental Index assesses key environmental criteria, such as use of recycled fibre or fibre coming from well-managed forests, energy use and CO2 emissions, water consumption and water pollution. Here, the evaluation depended on the creation chain outline. Water consumption attributed to roundwood production Total volume of consumption, which is generally related to gross national income of a country. The water footprint of printing and writing paper is estimated to be between 300 and 2600 m3/ton (2-13 litres for an A4 sheet). It is an essential naturalresourcefor basichumanneedssuchas food,drinking water and a healthy environment. Abstract: Carbon footprint and water footprint assessments can be powerful tools to guide sustainable food production systems. The water footprint, a concept founded by the author, is an indicator of direct and indirect freshwater use by a consumer or producer which can be used to analyse water usage along supply chains and assess the sustainability, efficiency and fairness of our water use. I. Water use is measured in water volume consumed (evaporated) and/or polluted per unit of time. Thus, based on the data presented in the UNESCO study, peanuts have the lowest fresh water footprint of comparable U.S. grown nuts. Hopefully, knowing about the environmental impact and carbon footprint of toilet paper will convince you to look for alternatives, or at least opt for toilet paper made sustainably with recycled waste paper. In 2015, the industry released Products that would seem not to involve any water at all -- or very, very little of it -- in fact have a significant water footprint. The water footprint of an A4 (=1/16 m 2) sheet of paper of 80 g/m 2 in l/sheet is estimated by multiplying the water footprint of paper in m 3 /t with a factor 0.005 (=80/16/1000). The water footprint of printing and writing paper is estimated to be between 300 and 2600 m3/ton (2-13 litres for an A4 sheet). single-sided 2-color print, (black / cyan) on matte paper. In this book about industrial water footprints, the creator of the concept – Arjen Hoekstra – discusses how freshwater is used to produce the goods and services consumed by individuals, communities and businesses. The water footprint accounting phase can result in a … The increasing interest in carbon footprint assessment has resulted from the growing public awareness of global India At the end of this paper, strategies to optimise the use of water in palm oil mills are. Water Footprint (WF) is a powerful tool for water management; it accounts for the volume of water consumption at high spatial and temporal resolution. “Footprint” evaluations — ecological, carbon, or water — determine the amount of a resource needed to produce a unit of a good. In this case study the total water footprint of one A4 sheet of wood free* uncoated paper (WFU) is 13 litres and for wood free coated (WFC) 20 litres, consisting of 60% green WF, 39% grey WF and 1% blue WF. production rate of POME for each t of FFB process. 324 liters of water is used to make 1 kilogram of paper. Paper’s water footprint is a lot lower than sometimes claimed. [Amazon] The water footprint of beef is much higher than those of other meats. It is part of the Special Issue “In Memory of Prof. Arjen Y. Hoekstra”. Background Thermal power plants convert heat into power in the form of electricity. Around 99% of the water footprint comes from the supply chain and the. There have been some claims that everyday paper products take excessive amounts of water to make. Your water footprint is the amount of water you use throughout the day. Despite huge advances in technology, the paper industry remains one of the biggest consumers of water on the planet. Direct Water Footprint . Furthermore, this paper exploits the general phase accumulation method to calculate the industrial water footprint by considering both the direct inputs and indirect water consumption. Water footprints were developed by the Water Footprint Network to assess the amount of water (in different types) that is consumed in producing food and other products. The increase in the consumption of animal products is likely to put further pressure on the world’s freshwater resources. Great start. The indirect water footprint of a solar-based FCEV (i.e., the water consumed in the supply chain of solar electricity) is over three times larger than its direct water footprint (the water used to produce hydrogen) (Figure 1). A bag’s impact is more than just its associated carbon emissions: Manufacturing a paper bag requires about four times as much water as a plastic bag. It would take 31,500,000 gallons of water to make the 450,000,000 paper napkins used in just one day. The water footprint is an indicator of water use that looks at both direct and indirect water use of … paper observes large differences among the WFs for specific types of primary bio-energy ... Water footprint 1. 14. COMPARE the impacts of different papers and varying amounts of recycled content.

And for pistachios, whether shelled or not shelled, the total estimated fresh water footprint is 18.8 gallons per ounce. Water footprint can apply to a product, a service, an individual, a country and even the world. A solar-based FCEV can achieve 100% emission reduction but requires 58% more water than driving a gasoline car. The carbon footprint— that is, the amount of greenhouse gas that is produced during the life cycle of a plastic bag—is less than that of a paper bag or a cotton tote bag. Making two pounds of paper requires 793 gallons of water—so think before you print! The water footprint of a country is defined as the volume of water needed for the production of the goods and services consumed by the inhabitants of the country. Approximately 0.5% of total US greenhouse gas emissions are attributed to data centers. Your answer: gallons. Water footprint (WF) is a comprehensive indicator of water resource consumption and pollution evaluation derived from human activities ( Hoekstra et al., 2011 ). water footprint appraisal of paper and pulp generation at a medium measured paper and pulp industry in Uttar Pradesh, India. For every tonne of paper produced, it takes around 54 cubic metres – or 54,000 litres -of water to produce. The estimated blue water footprint of the “oil to PET” steps was 2.64 gallons of water per pound (10 liters per kilogram). Results3.1. For paper-based products, there are three major factors that affect the carbon footprint: carbon sequestration in forests, carbon emissions generated during manufacturing and processing and avoided emissions associated with biomass fuel usage. The water it takes to produce the average American diet alone—approximately 1,000 gallons per person per day—is more than the global average water footprint of 900 gallons per person per day for diet, household use, transportation, energy, and the consumption of material goods. Indirect water use refers to the water use in the production chain of … REDUCE your impacts. Arjen Y. Hoekstra both inspired and enabled a community of scholars to work on … It presents an empirical analysis of water footprint values of an average respondent. Water is used both domestically and for agriculture and industry in the production of everything from food to paper. In order to better understand the water footprint of thermal power plants, this paper presents a simple, generic model to predict their water usage. These assertions may not consider that ‘green water’ is needed for healthy forests, that mills are typically situated where there is It includes the water you use directly from the tap, the water used to produce the food I eat, the products I buy, the energy I consume and even the water I save when recycling. Carbon footprint and water footprint of rice and wheat production in Punjab, India. See how many litres of water is needed to make 1 kg of agricultural products. Introduction Fresh water is a prerequisite for life on earth. Most water footprint studies, including the 2003 coffee study, are based on the Water Footprint Network. 13. This paper addresses the problem of hidden total water consumption in the framework of the modern consumer, hygiene, and dietary habits of the respondents at the household and individual level. Once all three are mapped, anticipated changes in supply can show where water demand will rise along the value chain. The average water footprint per calorie for beef is 20 times larger than for cereals and starchy roots. 12. Water footprint: the concept. Water Footprint is also a subset of Ecological Footprint and is a novel concept. White Paper: The Carbon Footprint Of Water. This paper commemorates the influence of Arjen Y. Hoekstra on water footprint research of the United States. This paper provides a comprehensive account of the water footprint of animal products, considering different production systems and feed composition per animal type and country. The concept of the water footprint has been developed to create an indicator of water use in relation to the consumption by people. The water footprint of any animal product is larger than the water footprint of crop products with equivalent nutritional value. water footprint calculates the volume of water used to assimilate the waste water based on ambient water quality standards.
