Mattsson and U. Sonesson, The Swedish Institute for Food and Biotechnology (SIK) The food industry is facing increasing pressure to improve environmental performance, both from consumers and regulators responding to consumer pressures.Environmentallyfriendlyfood processinghasbeendesigned toallow food manufacturers to understand better the effects their activities have on the environment and to take practical measures towards more sustainable production. Whendiscussingtheenvironmentalimpactoffoodproductionitisimportant to use a holistic approach, a systems perspective. As an example, it is not efficient to reduce the emissions from a processing plant if it results in, for example, larger losses of raw material, which in turn increases the emissions from agriculture. As the food supply chain is complex, environmental impacts can occur in different places and different times for a single food product. Life cycle assessment (LCA), discussed in Part I, provides a way of addressing this problem. LCA is a means of assessing the environmental impact of a product over its entire life cycle, from raw materials to the point of consumption. LCA allows businesses to see their role as contributors to the overall environmental impactofthesupplychain,andhowtheycanworkwithsupplierstoimprovethe environmentalprofileofproductstheymanufacture. LCAalsogivesbusinesses the opportunity to anticipate environmental issues and integrate the environmental dimension into products and processes, rather than just manage theenvironmentalimpactoftheirexistingoperations.PartIincludeschapterson the principles of LCA and its application to the production of vegetable, fruit, animal and seafood products as well as beverages such as coffee. Important issues directly related to food processing are energy and waste management.Foodproductioningeneralusessignificantamountsofenergyand produces relatively large amounts of waste, particularly packaging waste, both 2 Environmentally-friendly food processing fromsecondarypackagingandconsumerpackaging.Thefoodsector,atleastin industrialisedcountries,isthesinglelargestuserofconsumerpackaging.These issues are dealt with in Part II which concentrates on practical measures in improvingenvironmentalperformance.Itincludeschaptersontrainingandways of improving energy efficiency, waste treatment and recycling.

Berlin, The Swedish Institute for Food and Biotechnology (SIK) 2.1 Introduction Life cycle assessment (LCA) is a tool for evaluating the environmental impact associated with a product, process or activity during its life cycle. LCA is suitable for several purposes. LCA provides knowledge of a product and its relatedenvironmentalimpact.Italsomakesitpossibletoisolatewhichstagesin the life cycle of a process or product make the most significant contribution to itsenvironmentalimpact.OtherreasonsforundertakinganLCAstudycouldbe to assess improvements or alternatives, or to compare products, processes or services. Environmental communication such as environmental product declaration (EPD) can be based on LCA, and it can also be used as an instrument in environmentally adjusted product development. Life cycle assessment is one of the tools included in the larger area of environmental systems analysis and is today one of the most commonly used tools within the subject. LCA has its roots back in the 1960s, when interest in energy requirement calculations started. During the oil shortage in the 1970s research was undertaken which included life cycle thinking for energy calculations and emissions released during energy production. However, after the oil crisis subsided, interest in LCA faded, but with the increased interest in the environment in the 1980s a revival of LCA occurred. Since 1990 LCA has expandedenormously,andthenumberofstudies,publications,conferencesand workshopsisstillgrowing(Lindahletal.,2001).TodayLCAisrecognisedasan ISO standardised method (ISO 14040–14043, 1997–2000).
