1. Steigender Energiebedarf und ein Recht auf Kühlung? Darf es ihn geben, den Anspruch auf eine Klimaanlage und einen Kühlschrank – ähnlich wie das Recht auf eine Heizung? 2. Kühle Kette für eine gesunde Versorgung Nach Schätzungen der Weltgesundheitsorganisation (WHO) verderben durchschnittlich 30 Prozent, in tropischen Ländern sogar 50 Prozent der Lebensmittel mangels angemessener Lagerung. 3. Grüne Technik und Wertschöpfung Das Zauberwort heißt Ressourceneffizienz. Der Schlüssel in der Kältetechnik dafür sind natürliche Gase. 4.

Refrigerators and air conditioning units feature high on the wish lists of people in hot countries. The International Energy Agency (IEA) calculates that by the year 2030 the energy consumption for air conditioning in developing countries and emerging nations will be four times what it is today. It is often the case that the gases used as refrigerants are produced chemically. They are damaging to the ozone layer and accelerate climate change. By contrast green technologies use natural gases in the cooling process, are more energy efficient and can be driven by sun or wind power.

This document will examine the technical, safety and administrative problems related to the use of flammable blowing agents in the production of extruded polystyrene boards (XPS). The document focuses on production of XPS rather than the design and certification of the XPS boards itself. The explanations, descriptions and examples are specifically focused on safety elements required for a proper production. The producer of XPS should always be aware of the product quality and on the basis of this knowledge eventually increase the safety system.

GIZ (former GTZ) Proklima has compiled this publication to provide information on natural foam blowing agents as ozone- and climate-friendly alternatives to HCFCs. The first section of the book covers policy-related aspects of technology transition towards natural foam blowing agents and examines the impact legislative changes have on development and adoption of alternative technologies. The second part deals with the use of natural blowing agents in rigid and XPS foam, the conditions for conversion and special technologies. Part 3 comprises case studies from developing countries.

This project is part of the International Climate Initiative (IKI) of the Federal Ministry for Environment, Nature Conservation, Building and Nuclear Safety (BMUB). It is the first global project on ODS waste management dedicated to the development and implementation of integrated strategies for reducing the emissions of Ozone-depleting substances containing waste.

Carbon tetrachloride (CTC) is a solvent and cleaning agent used widely across many industry segments. Its high solvency power, low cost and the fact that it is non-flammable made it popular in many cleaning applications.

Currently, all supermarket refrigeration systems in Southern Africa operate on fluorinated refrigerants with high ozone-depleting and/or global warming potentials. Modern, environmentally friendlier technology based on natural refrigerants is still completely unknown there and is seen with some concern. Most equipment owners, refrigeration engineers and service technicians have been reluctant to discuss these technologies due to potential safety issues.
