Una cagada total.
En el pais se fabrican lamparas comunes. No hay tecnolgia ni maquinarias para fabricar de bajo consumo. Ni la va a haber si encima le quitan los aranceles de importacion.
Todo una basura para tapar la falta de inversion en energia que crea un problema mucho mayor que el que reduce. La contaminacion.
Saben que hay dentro de las lamparas de bajo consumo ? Mercurio.
Hay una conciencia popular sobre el tratamiento de residuos contaminantes ? No
Va a haber conciencia dentro de dos años ? No.
Donde van a parar las lamparas quemadas ? Al basural.
Quienes moriran intoxicados por mercurio ? Los pobres.
Me parece correcta la medida, ya que tendra vigencia recien a partir del 2011, eso les da a las fabricas en Argentina 2 años para un recambio de tecnologia para asi ser capaces de producir lamparas de bajo consumo.
Pero coincido en lo que decis sobre la falta de conciencia de la gente, especialmente la gente pobre, pero sin llegar al extremo de que moriran intoxicados, salvo que se pongan a aspirar lamparas rotas. Lo que si se generara sin dudas es un impacto en el medio ambiente por desechar las lamparas incorrectamente (lo cual haria inutil el impacto ambiental que se evita por no usar incandecentes)
Broken and discarded lamps
Public adoption of CFLs in the U.S. has been slowed by one widely-circulated story of how the Maine Department of Environmental Protection detected mercury contamination following a residential CFL breakage incident, and the homeowner was presented with a US$2,000 estimate from an environmental cleanup firm.
Although initially dismissed as an overreaction, subsequent scientific studies by the Maine DEP and also Brown University in 2008 have confirmed that—contrary to earlier belief—the amount of mercury released by a broken CFL bulb greatly exceeds EPA safety standards.
Spent lamps should be recycled to contain the small amount of mercury in each lamp, in preference to disposal in landfills. Only 3 percent of CFL bulbs are properly disposed of or recycled. In the European Union, CFLs are one of many products subject to the WEEE recycling scheme. The retail price includes an amount to pay for recycling, and manufacturers and importers have an obligation to collect and recycle CFLs. Safe disposal requires storing the bulbs unbroken until they can be processed. In the US, The Home Depot is the first retailer to make CFL recycling options widely available.
Special handling instructions for breakage are currently not printed on the packaging of household CFL bulbs in many countries. The amount of mercury released by one bulb can exceed U.S. federal guidelines for chronic exposure. Chronic however, implies that the exposure takes place over a long period of time. The mercury in CFLs is hazardous because one broken bulb can spike mercury contamination as high as 100,000 ng/m3 of air—some 300 times the EPA chronic limit of only 300 ng/m3 of air. The Maine DEP study confirmed that, despite following EPA best-practice cleanup guidelines on broken CFLs, researchers were unable to remove mercury from carpet, and any agitation of the carpet—particularly by young children playing—created spikes as high as 25,000 ng/m3 of air, even weeks after the initial breakage. Conventional tubular fluorescent lamps have been used since 1938 with little concern about handling, although these are not generally subjected to the rigours of ordinary household use. The U.S. Environmental Protection Agency recommends that, in the absence of local guidelines, fluorescent bulbs be double-bagged in plastic before disposal.
The Maine DEP study of 2008 compared clean-up methods, and warned that the EPA recommendation of plastic bags was the worst choice, as vapours well above safe levels continued to leach from the bags. The Maine DEP now recommends a sealed glass jar as the best repository for a broken bulb.
The first step of processing CFLs involves crushing the bulbs in a machine that uses negative pressure ventilation and a mercury-absorbing filter or cold trap to contain mercury vapor. Many municipalities are purchasing such machines. The crushed glass and metal is stored in drums, ready for shipping to recycling factories.
According to the Northwest Compact Fluorescent Lamp Recycling Project, because household users have the option of disposing of these products in the same way they dispose of other solid waste, "a large majority of household CFLs are going to municipal solid waste". They additionally note that an EPA report on mercury emissions from fluorescent tube lamp disposal indicates the percentage of total mercury released from the following disposal options: municipal waste landfill 3.2%, recycling 3%, municipal waste incineration 17.55% and hazardous waste disposal 0.2%.
