In Europe, 2,5 billion tonnes of waste are produced every year, but only 600 million tonnes are recycled or reused. How and how much they contribute in the various EU countries and EPR systems to closing waste/resources loop.
In the EU, according to the web pages dedicated to waste, we currently use 16 tonnes of material per person per year, of which 6 tonnes become waste. In 2012, total waste amounted to 2.5 billion tonnes and only a limited share of this total was recycled. The rest was landfilled or burned, of which some 600 million tonnes could be recycled or reused. Indeed, despite the ongoing improvements, the European economy continues to lose a significant amount of potential “secondary raw materials” present in the waste streams, such as metals, wood, glass, paper, plastics, organic matter and inert materials.
Despite acknowledging the unsatisfactory situation, policies do not seem to follow at the right pace. Indeed, figures confirm a trend that ZeroWasteEurope defines as “worrying”: recycling continues to stagnate. Official Eurostat data (see figure 1) show that landfilling and disposal into water bodies have increased since 2008, overtaking even recovery in 2012, while incineration is stable. This clearly is not the wisest approach to deal with the flows of products at the end of their life cycle.
EPR Systems: Streams Under Control
One of the policy concepts that can help closing the waste-resources loop and that is increasingly being used around the world – as can be seen in figure 2 – is Extended Producer Responsibility (EPR). EPR as a policy stems from the polluter-pays principle, which is a pillar of EU environmental policy. It is defined in the 2001 OECD Guidance as “an environmental policy approach in which a producer’s responsibility for a product is extended to the post-consumer stage of a product’s life cycle.” There are several types of EPR policies, the most widespread being take-back, Advance Disposal Fees (ADF) and deposit/refund schemes. Very often, the obligations set in legislation, or the targets set voluntarily by the producers themselves, are pursued through waste-stream-specific Producer Responsibility Organisation. When not exclusive, these operate in competition; self-compliance by the individual producers is usually a viable option as well.
EPR as a policy approach in the EU is adopted in the End of Life Vehicles (ELV) Directive of 2000, in the Waste of Electric and Electronic Equipment (WEEE) Directive of 2012 and in the Batteries Directive of 2006. EPR is widely used in EU Packaging and Packaging Waste policy (1994 Directive). Finally, the Waste Framework Directive of 2008 sets some principles for the implementation of EPR. And indeed, in many member states, EPR policies or voluntary agreements have been put in place for products not covered by EU legislation, as can be seen in table 1.
Key aspects to consider for assessing how successfully these policies are implemented concern the technical performance (quantities put on the market, waste generated, collection and treatment, steering of innovation towards enhanced recyclability) – which is represented through:
Here, we will concentrate on the technical aspect. Let us see what data and statistical analysis tell about materials covered by EU or national policies.
Different Performances in Different Countries
A recent study funded by the European Commission to examine waste management systems in sixteen EU member states (MS) found that official Eurostat data on waste streams, collection and recycling are not that reliable: “Even after extensive investigation, there is a severe lack of comparable information available for economic and technical performance.” In order to overcome the inconsistencies, the authors carried out an in-depth study of 36 cases (specific waste streams in particular countries), including the four products covered by EU legal acts (ELV, WEEE, batteries, packaging), plus two others for which EPR schemes are present in several European states (graphic paper and oils).
The evidence thus collected is sufficient for the authors to argue in favour of strengthening EPR policies, as these led to “undeniable improvements in waste recycling and recovery performances in all MS.” However, they confirm that technical performances are highly variable throughout Europe.
As general conclusions, the study highlights that the best performing schemes are not, in most cases, the most expensive, that the fees paid by the producers vary greatly for all product categories and that no single EPR model emerges as the best performing and the most cost-effective. Each material stream has its own characteristics, and local conditions greatly influence the efficiency of EPR schemes. All that can be said is that, on average, where such schemes are in place, the European waste management hierarchy is complied with better than where the market does not have a specific institutional framework and is left to auto-organisation. The latter often leads to the same results, but it is often required for the right solutions to emerge and there is still plenty of room for free-riding and cheating.
Interesting conclusions are also drawn by other in-depth studies, investigating the functioning of EPR schemes in the context of various non-European OECD countries, such as e.g. of Japan’s WEEE Recycling Act (Tasaki et al., 2007), finding that collection of manufactured goods have enjoyed mixed success (due to illegal disposal and exports), but the recycling of collected goods has performed well. The most interesting results of the enforcement of comprehensive recycling laws in Japan are in the advance of innovation in environmental technologies, and these contributed to an increased level of recycling. A statistical study on U.S. households’ attitude towards plastic water bottle deposit/refund (Viscusi et al., 2011), concludes that “for the population at large, a fascinating transformation in behaviour occurs with the introduction of incentives to recycle,” since “the change in the recycling rate exhibits a jump as people shift from being nonrecyclers to diligent recyclers.” Also Batson and Eggert (2012) find that in the U.S. there is a substantial difference in recycling rates between states without a deposit/refund (roughly 30%) and those with a deposit/refund (roughly 70%), regardless of the deposit rate. Kaffine and O’Reilly (2015) carried out, on behalf of the OECD, a wide review of similar empirical studies, finding that:
Also country-specific conditions and local factor – including cultural and behavioural ones – have a great influence on performance, as the great discrepancies in CRs and RRs between countries that have similar schemes show.
One important general conclusion that can be drawn from the empirical studies on EPR scheme, which is worth underlying here, is that the presence of compliance schemes raise the ability of the countries where they are in place to achieve collection and recycling targets. Kaffine and O’Reilly label this ability “Environmental effectiveness of EPR,” and state that “the general consensus in the academic and non-academic economic literature is that mandates such as take-back requirements and recycling content standards do increase the amount of material recycled and the recycling rate.”
An important feature investigated in the literature concerns the quality of materials collected. Here the evidence is scarcer and definitely not conclusive. E.g. Acuff (2013) finds that while collection methods, like single stream recycling, have positive aspects such as increased diversion rates (more material sent from households to recycling centres), they also increase contamination rates and the amount of residual material ultimately diverted to landfills by the recycling centres. An issue paper by the International Solid Waste Association (ISWA, 2014) provides further references to relevant studies and highlights other aspects to which attention should be paid in designing EPR compliance schemes.
Outside EPR, Streams are Hardly Studied
Waste streams that are not (yet?) widely targeted by EPR policies are, unfortunately, not very much studied in this context, although the studies often aim at clarifying why and how new compliance schemes should be set up. Biomasses are a case in point.
In the EU-28, 1.7 tonnes of biomasses are collected each year and a further 0.7 million tonnes of biomass is derived from such production as waste by-product. In addition, 0.17 billion tonnes are imported, including exclusively or mainly biomass and a little less than 0.15 billion tonnes are exported. Overall, biomasses, including cutting, harvesting and cultivation by-products that each year are turned into waste, EU’s waste water or emissions amount to approximately 2.4 billion tonnes.
Another one is construction and demolition (C&D) waste. While the waste framework directive provides for a target of reuse, for this kind of waste, recycling and other forms of material recovery of 70% by 2020, it does not envisage specific instruments. C&D waste is also usually not addressed in national EPR policies, as member states are still in the process of integrating the European target into national legislation. In 2012, according to a report for the DG Environment (IEEP, BIO et al., 2012), EPR schemes were in place (in some cases as voluntary producers’ initiative) in Austria, Ireland, Germany, Malta, Spain and the UK; and since then, some more may have been created, whose effects would not alter the analysis of the latest available data. The bad news is, however, that there are many other reasons why data should be handled with care, knowing that any possible conclusion should require confirmation.
C&D waste includes many different materials. This implies that the concept of “quantities put on the market” becomes difficult to apply to C&D material streams. In principle, quantities put on the market should be calculated by broad product categories, i.e. for groups of products used in construction determined according to the materials they are made of. Moreover, the life cycle of C&D materials being much longer than a year, the concept of collection rate loses some of its usefulness, as C&D waste produced (maximum limit for C&D collected) in a given year may come only for a minor fraction from materials used in construction activities in the same year.
Let us therefore concentrate on a fraction of C&D waste, namely to that of mineral waste, excluding metallic minerals. Their amount can be compared to that of the apparent consumption of minerals (and deriving products) used in construction.
Eurostat data (see table 2) on C&D waste provide an interesting starting point. However, it must be pointed out that on some occasions data comparison seems rather arbitrary: as mentioned before, at row level, data suffer from imperfections affecting comparability and at column level, because national mineral consumption accounts for mineral raw materials extracted from the domestic market, instead of the domestic manufacturing of products derived from them. But, since it adds product imports and subtracts exports, these data can be considered an acceptable approximation of quantities placed on the market.
In the suggested table, next to indicators equal to collection (b/e) and recycling rates, we included a particularly significant indicator, “the satisfaction rate of domestic demand for construction materials from recycled sources (d/d+e). As it appears, only one of the 19 countries not reaching 5% of such indicator is amongst the 6 claiming to have EPR systems in place. This is Malta, whose EPR system we were not able to verify through operational data; nor does it seem to deal with waste one of the 6 authorized C&D authorized collection systems, listed on the Malta Environment and Planning Authority web page.
In the bottom part of the table the average indicators of countries with a compliance scheme have been calculated, comparing them with indicators of those without them. The better performance of the former is mainly due to the higher ratio between treated waste and quantity of minerals placed on the market (columns b/e), rather than to high recycling rates (column b/d).
Within the limited significance of data regarding the effects of compliance schemes, the evidence is positive. Admittedly, it is only an indication, but something nonetheless.
