http://ecoskimple.org/de/?q=Rolf-Albern-Biomass-Energy - Biomass is biological material derived from living, or recently living organisms, like alcohol fuels, waste, and wood. It is a renewable energy source because the energy it contains comes from the sun. Biomass is the oldest source of renewable energy known to humans and supplies almost 15 times as much energy in the United States as wind and solar power combined. Biomass energy has been used since people began burning wood to cook food and keep warm.

The world's largest medical trade fair is the MEDICA in Dusseldorf, where each year about six hundred speakers introduce the latest medical knowledge of their discipline and some three hundred suppliers present their latest discoveries and developments. Outpatient as well as inpatient technological tools up to new digital processes of health care are presented in Dusseldorf. So, all in all the entire modern achievements of world medicine are showcased there.

For manufacturers of medical products the MEDEC Europe is the most important one of all trade fairs on the European continent. It provides its visitors comprehensive information on the current range of products and services in the field of development and manufacturing of medical devices. At the MEDTEC Europe manufacturers are given the possibility to order the latest medical equipment as well as individual components.

Due to the fact that at the MEDTEC Europe, world's leading suppliers of medical materials and technologies meet up, the offer includes the following areas:

- Assembly and manufacturing technology

- Materials for all application areas

- Packing, sterilization and clean room systems

- Synthetic / disposable products and diagnostics

- Outsourcing / contract manufacturing

- Motors, pumps, and motion control

- IVD manufacturer

- Technology for quality assurance and control

- Accurate and high-performance cutting / subtle cutting

- Medical Electronics

In the field of biotechnology, the BIO-Europe is of greatest importance. At this annual trade fair the best known names of the industry as well as senior decision makers meet in the context of workshops and forums in order to deal with future key themes. In addition, at the BIO-Europe, the latest products and technologies are showcased.

The word plastic derives from the Greek plastikos- fit for molding and plastos- molded. Plastic is a wide range of synthetic or semisynthetic organic amorphous solid materials suitable for the industrial or commercial products. Plastics are polymers of high molecular mass, that may contain other substances to reduce costs or improve performance. Modern manufacturing processes allow them to be pressed, cast, or extruded into different kinds of shapes—such as bottles, fibers, boxes, plates, films, and much more.

There are two types of plastics:

Thermosets, that can melt and take shape once, and stay solid after they have solidified,
Thermoplastics, that will soften and melt when enough heat is applied, for example: polyvinyl chloride, polystyrene, polyethylene, and polytetrafluoroethylene (PTFE).
Plastics can be classified by the chemical process used in their synthesis; for example, as cross-linking, condensation or polyaddition.

Plastics can also be classified by their chemical structure, for example, silicone, halogenated plastics, polyesters, polyurethanes or the acrylics.

They can also be ranked by various physical properties, such as tensile strength, resistance to various chemical products, density, glass transition temperature, etc.

Other classifications are based on qualities that are relevant for manufacturing or product design, for example, electrically conductive, elastomer, biodegradable, structural, the thermoplastic and thermoset, etc.

Plastics have already displaced many traditional materials, such as paper, wood, stone, leather, metal, glass, horn and bone; and ceramic.

They are used in a huge range of products because they can easily be manufactured, they are relatively low cost and imperviousness to water and versatility.
