ecopractic In what regards waste management, the GHG that has the biggest contribution to global warming are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). All three are generated by activities related to waste management. ?e impact of solid waste management at European level, in what regards global warming caused by GHG emissions, is largely caused by methane – CH4 emissions, due to the biodegradation of waste in waste storage anaerobic conditions. About one third of the EU’s anthropic CH4 emissions can be attributed to this source. On the other hand, only 1% of N2O emissions and less than 0.5% of CO2 emissions are associated with the disposal of solid waste. Since GHG related to human activities are strongly connected to CO2 emissions (about ¾ of the impact owed to global warming – by burning fossil fuels (coal, oil) – and of deforesting), the standard unit used is CO2e = carbon dioxide equivalent or “carbon footprint,” a term of reference that makes it easier to evaluate the extent to which a particular amount of gas contributes to the greenhouse e?ect. ?e equivalence describes the same warming potential in W/m2 (global warming potential - GWP) for a particular amount and mixture of gas, when the measurements refer to a pre-established time span (usually 100 years). ?e waste industry has an important position and potential for GHG reduction activities, a reduction opportunity that has not yet been fully exploited. ?e waste sector is o?ering an impressive portfolio of e?cient and practically demonstrated technologies that can contribute to GHG reduction. ?e technologies must be adapted and implemented in line with local customs and needs, thus leading to a signi?cant global reduction of GHG emissions. Waste management related activities, by preventing waste generation and minimizing, reusing and recycling waste, also have a signi?cant potential to reduce GHG emissions, due to the preservation of raw materials and fossil fuels. Aerobic and anaerobic technologies of biological treatment can help with the recovery and transformation of organic waste, ultimately using them to improve soil quality and/or as fertilizers. ?ese processes reduce GHG emissions by locking biogenic carbon in the soil, improving the soil’s physical properties and enriching it with nutrients. Waste is an important source of renewable energy. Incineration and other “waste-to-energy” thermal processes, recovery and use of gas from waste storage and the use of biogas resulted from anaerobic fermentation can play a very important part in the reduction of fossil fuel consumption and GHG emissions. ?e precise measurement and quanti?cation of GHHG emissions is essential to determining realistic targets and monitoring them on all levels. To calculate the CO2 footprint of the waste management sector in general and the packaging waste management segment in particular, adequate date is necessary about the entire material and energy life cycle. Current calculation methods and those that are being developed at waste management level can become a valuable database for the evaluation of GHG emissions. For packaging and packaging waste management systems, supplying information to responsible companies, consistent with the calculation method adopted for determining the CO2 footprint, is one of the most important contributions to the evaluation of global environmental performance and a consistent informational addition that is important for the promotion of activities related to sustainable packaging design and manufacturing. Last but not least, one must mention an increase in ?nancial resilience due to the fact responsibility for calculating GHG emissions (carbon footprint) was given both to waste management companies and to companies responsible for recycling and recovering various kinds of waste. ?is is even more important to mention now, at this time of crisis, which makes the matter of energy and raw material consumption a highly sensitive topic. revisinG euroPean tarGets for PackaGinG Liliana nichita operations manager ?ere is currently an ongoing European project to consult the public about a revision of the targets set by various European directives in the ?eld of collection, storage and recycling of packaging waste. ?e public consultation was held between June 4 and September 10, 2013 and it targeted all parties concerned, including citizens. ?e project is aimed at identifying problems and possible solutions for the goals set by the Waste Framework Directive, the Waste Storage Directive, the Packaging and Packaging Waste Directive. ?e reasons for reviewing the directives are grounded in two major issues: on the one hand the revision is a response to the revision clauses included in the directives and on the other hand, it correlates the targets with the European Commission’s objectives to promote resource e?ciency. ?e primary goal is to harmonize recycling goals, both across di?erent directives and in relation to environmental policy documents at European level. In what regards the Packaging and Packaging Waste Directive, we expect an increase in targets, both at global level and per type of material, with more pressure on the plastic goal, which is expected to reach at least 40%. ECO-ROM AMBALAJE has presented its point of view on the matter both to the authorities and to interested professional associations. 7
