Refining Used Lubricating Oils


Book Description

Used lubricating oil is a valuable resource. This book examines recycling processes for a range of products with different properties and different criteria. It also compares the various recycling methods and resulting products to conventional products obtained from original refining processes. The reviews, data, and comparisons provided by the authors allow readers to identify which processes are likely to produce a product with specific properties, and enable them to combine this with an analysis of the economic data to identify attractive oil recycling propositions.




Used and Rare


Book Description

Years ago, the Goldstones fled high-paying jobs in Manhattan to live and write in the Berkshires. Enough of an overachieving spark remained to ignite a contest when the search for inexpensive birthday gifts began. While Lawrence settled for a bath brush, Nancy tracked down a ten-dollar copy of War and Peace, and the couple's love affair with book collecting was born. What started as a last resort on the quest for a cheap gift soon became an addiction. The Goldstones found themselves visiting every rare-book store between Boston and Manhattan, spending ever increasing amounts of money on first editions, leather-bound classics, and out-of-print volumes. Along the way, they gained an education in books - and in people - that we can all savor.




Exports of Nordic Used Textiles


Book Description

The Nordic Council of Ministers’ Green Growth Initiative highlighted the need for comprehensive collection, reuse and recycling of used textiles as part of a circular economy. Over 100 000 tonnes of used textiles are already collected each year in Nordic countries. This is for the most part carried out by charities to fund their charitable activities. Around three quarters of these textiles are sold on global markets. Does the export of used textiles support the circular economy through reuse and recycling, or are we simply exporting waste to countries that don’t have the facilities to deal with it? And does the export have a negative effect on textile industries in receiving countries? This report answers these questions by tracking flows of exports to their final destinations, and by estimating the socio-economic and environmental impacts arising from their subsequent treatment.



















Safety and quality of water used with fresh fruits and vegetables


Book Description

During fresh fruit and vegetables (FFV) production, water is used for a variety of purposes. Even the water was conventionally treated and disinfected, it may still potentially contain human pathogens, albeit at low concentrations. A risk assessment, appropriate to the national or local production context, should be conducted to assess the potential risks associated with a specific water source or supply in order to devise the appropriate risk mitigation strategies. Since the 48th session of Codex Committee on Food Hygiene (CCFH) noted the importance of water safety and quality in food production and processing, FAO and WHO has undertaken the work on this subject. This report describes the output of the third in a series of meetings, which examined appropriate and fit-for-purpose microbiological criteria for water used with fresh fruit and vegetables. The advice herein will support decision making when applying the concept of fit-for-purpose water for use in the pre- and post-harvest production of fresh fruit and vegetables.
