ecopractic RE CY CLE Both waste management companies and those responsible for the recovery and recycling of various kinds of waste can have a signi?cant contribution to the reduction of greenhouse gas emissions, by implementing the latest technologies. to reduce global warming G reenhouse Gases (GHG) are those gases that absorb and emit infrared radiations, which is a fundamental process in the generation of the greenhouse effect: maintaining a hospitable temperature on the planet’s surface. The greenhouse effect is a natural one and the absence of this gas could lead to an over 30 degree Celsius drop in the average temperature of the Earth’s surface from the current average temperature of 15 degrees. Nevertheless, human activities generate significantly more greenhouse gases than necessary and this has led to an ongoing global warming phenomenon and to other climate changes associated with this increase in GHG concentration in the atmosphere. For instance, the CO2 concentration in the atmosphere has grown from 315 ppm (parts per million) in 1959 to 387 ppm in the present. Romania’s National Strategy on Climate Change 2013-2020 states the following: “The global warming process and its impact on the climate system are considered unequivocal, as per the fourth Evaluation report of the Intergovernmental Group on Climate Change published in 2007, and they are confirmed by a 0.9 C° increase in the global average temperature, compared to the average temperature during the preindustrial age (which has accelerated over the last 50 years), by an increase in sea and ocean levels (also more accelerated in recent years: 3.11 mm/year between 1993 and 2003 compared to 1.8 mm/year between 1961 and 2003), by the accelerated melting of glaciers and ice caps, by an increase in intensity and frequency of extreme weather phenomena, etc.” The same report talks about an approximately 80% increase in CO2 emissions between 1970 and 2004 (28% between 1990 and 2004). The highest increase in GHG emissions between 1970 and 2004 was reported in the energy sector (145%), followed by the transportation sector (120%). 6 Page by dr. eng. mihai florin ?olea, technical manager By analyzing the National Inventory of Greenhouse Gas Emissions (INEGES), the same strategy identi?ed the economic sectors that need speci?c mea sures to reduce GHG emissions: • Energy • Industrial processes • Agriculture • Land Use, Changing Land Use, Silviculture • Waste management ?e strategic targets accepted by Romania until 2020, in comparison with reference year 1990, are as follows: • reducing greenhouse gas by 20% • reducing ?nal energy consumption by 20% by increasing energy e?ciency • producing 20% of the necessary energy from renewable sources
