Soil pollution: a hidden reality


Book Description

This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.







PVC waste treatment in the Nordic countries


Book Description

The aim of the project was to map PVC waste streams in Denmark, Sweden, Norway and Finland. The available estimates are made occasionally, mostly within the frames of different projects and are not based on any formalized official reporting system or other rigorous accounting scheme. Overall, a large part of PVC waste ends up in mixed waste fractions and is eventually treated in waste-to-energy plants. Landfilling of PVC waste is banned in two countries, but some exceptions exist. Norway is the only country that treats some PVC waste as hazardous waste. The current waste treatment situation in the four Nordic countries is driven by several factors, such as diverse origins of PVC products, some specifics of the Nordic market, rather low focus on PVC waste in policy strategies or plans, technical issues regarding incineration of PVC waste, and the lack of domestic recycling.







Hazardous substances in plastics


Book Description

The aim of the project is to create knowledge on how plastics recycling can increase without increasing the risk of emitting hazardous substances to the environment.The first general conclusion is that to be able to increase recycling there are measures needed at different levels. The following areas are of interest: • Legislation: new legislation is not necessary, but harmonisation and clear guidance to the existing one is. • Market: to create a market safety on content is needed. • If substances added are less hazardous the recycled raw material would be “more safe” to use. • There should be higher attention put on the knowledge of the recyclers. • Traceability and content: Further work on labelling reaching the recycle part of the value chain needs to be developed. It is also needed to develop a systematic approach towards risk assessments linked to recycling.

Plastic Waste and Recycling


Book Description

Plastic Waste and Recycling: Environmental Impact, Societal Issues, Prevention, and Solutions begins with an introduction to the different types of plastic materials, their uses, and the concepts of reduce, reuse and recycle before examining plastic types, chemistry and degradation patterns that are organized by non-degradable plastic, degradable and biodegradable plastics, biopolymers and bioplastics. Other sections cover current challenges relating to plastic waste, explain the sources of waste and their routes into the environment, and provide systematic coverage of plastic waste treatment methods, including mechanical processing, monomerization, blast furnace feedstocks, gasification, thermal recycling, and conversion to fuel. This is an essential guide for anyone involved in plastic waste or recycling, including researchers and advanced students across plastics engineering, polymer science, polymer chemistry, environmental science, and sustainable materials. - Presents actionable solutions for reducing plastic waste, with a focus on the concepts of collection, re-use, recycling and replacement - Considers major societal and environmental issues, providing the reader with a broader understanding and supporting effective implementation - Includes detailed case studies from across the globe, offering unique insights into different solutions and approaches




Principles of Food Sanitation


Book Description

Large volume food processing and preparation operations have increased the need for improved sanitary practices from processing to consumption. This trend presents a challenge to every employee in the food processing and food prepara tion industry. Sanitation is an applied science for the attainment of hygienic conditions. Because of increased emphasis on food safety, sanitation is receiving increased attention from those in the food industry. Traditionally, inexperienced employees with few skills who have received little or no training have been delegated sanitation duties. Yet sanitation employees require intensive training. In the past, these employees, including sanitation program managers, have had only limited access to material on this subject. Technical information has been confined primarily to a limited number of training manuals provided by regulatory agen cies, industry and association manuals, and recommendations from equipment and cleaning compound firms. Most of this material lacks specific information related to the selection of appropriate cleaning methods, equipment, compounds, and sanitizers for maintaining hygienic conditions in food processing and prepara tion facilities. The purpose of this text is to provide sanitation information needed to ensure hygienic practices. Sanitation is a broad subject; thus, principles related to con tamination, cleaning compounds, sanitizers, and cleaning equipment, and specific directions for applying these principles to attain hygienic conditions in food processing and food preparation are discussed. The discussion starts with the importance of sanitation and also includes regulatory requirements and voluntary sanitation programs including additional and updated information on Hazard Analysis Critical Control Points (HACCP).
