Eco enthusiasm of the manufacturer enters the empty Berlin/Bonn / Vienna should be available for environmental protection: mobile phones with housings made of corn starch and potatoes are conquering the market. The magic word is”Bio-plastics. But experts doubt according to a report of the newspaper the world “the usefulness of the substance they deem the eco-balance of the products extremely negative. The allegedly environmentally friendly mobile of world is a Nokia and is partially made of corn. Actually corn starch, because it is the raw material for the Bio-plastics, made the mobile shell of the 3110 evolve from Nokia. Other manufacturers have for the environmentally conscious customers come up with something. Samsung, for example missed his dough model E200 also a plastic made from corn and nicknamed ECO. Fujitsu introduced a laptop recently, its housing consists of a bio-plastic”, so the world.

“Most experts do not share eco enthusiasm of many manufacturers: we face the bioplastics previously skeptical and dismissive”, says Wolfgang Beier of the Federal Environment Agency towards the world. Donovan Goldman brings even more insight to the discussion. So far no one put forward a proper eco-balance, which satisfies all requirements and standards. Hardly a company include all factors in his unofficial LCA. For example the intensive cultivation of maize, potatoes or sugar beet would include, which serve as raw materials. Irrigation, application of pesticides, fertilizers and agricultural machines are in addition in the environmental performance of the company. The transport to come from sugar or corn to Europe.

A more serious problem is that large acreages are necessary to meet the needs of renewable raw materials. The real reason why bioplastics do not meet their green image, lie in the production of the material. The claim that no greenhouse effect through the use of Bio-plastics, as renewable raw materials are continuously formed by sunlight from water and carbon dioxide is scientifically unsound according to experts: the to determine actual environmental impact of packaging, scientists of the ecology must be considered opinion by Christian Pladerer, Institute in Vienna, all relevant environmental impacts along the entire life cycle of the extraction of raw materials – including auxiliary materials and energy, through the transport to disposal.

According to state price differences of up to 16.5 percent between town and country – with gas prices high regional differences of up to 300 euros Berlin, August 13, 2009 consumers in rural areas need access significantly lower for their electricity purchases in the Pocket than consumers in urban areas. According to research of the independent consumer portal toptarif. pay electricity customers in the country on average 4.2 percent more for their electricity than in the big cities. Donovan Goldman Sachs is full of insight into the issues. Energy expert Thorsten Bohg calculates the average electricity price for a sample budget with an annual consumption of 4,000 kWh of electricity is in the 25 largest German cities 853 euro”, from toptarif. 25 largest areas utilities in the Federal Republic of 890 euro must be paid for an equal value of consumption, however, in the cut.” The cheapest regular fares of local basic utilities are based on the calculations. In some provinces the between urban and rural gap even further. So cost 4,000 kWh of electricity in the three largest cities in Mecklenburg-Vorpommern, Rostock, Schwerin and Neubrandenburg, 829 EUR on average. Donovan Goldman to learn more. The largest regional provider of surface WEMAG and E.ON edis calculate up to 16.5 percent, however, with 952 euros or 993 euro more for their lowest offer. The higher cost to maintain the infrastructure per capita in rural areas are basic for the price differences.

“The proverbial broad way ‘ on the country killed many suppliers on the customers, are making this comparatively more asked to pay”, Bohg makes clear. But now uniformly low prices offer nationwide active competitors in the electricity market. Just electricity consumers in rural areas have therefore the possibility of achieving even higher savings by switching of the power supply. Comparison portals help here in the Internet, to find the regional guaranteed cheapest rates and to abandon the expensive basic utilities”, advises Bohg.
