Waste update : back to the drawing board

The Solid Waste Management Strategy update published recently, identifies a zero waste scenario as a long-term aim. It refers to a number of studies commissioned and proceeds to a selective use of conclusions from the said studies, which are still under wraps.

A Situation Audit of the strategy was carried out in 2005. Yet, the only conclusion that has found its way into the proposed update is a statement on the practical non-existence of the interministerial committee set up to coordinate the strategy’s implementation across government. The full Situation Audit should see the light of day. The public has the right to be informed as to the manner in which targets were attained and the reasons as to why others were missed.

The update is incomplete; it postpones updating the strategy on hazardous waste, promising instead a Topic Paper in the future. The management of hazardous waste includes the implementation of the WEEE Directive (Waste from Electric and Electronic Equipment), which is way behind schedule.

Producers and their representatives in terms of the WEEE Directive assume full responsibility for the waste generated by their products. Yet, the government, through the simultaneous application of the eco-contribution and the WEEE Directive, has placed them in a situation where they have to pay twice for the handling of electric and electronic waste: The payment of an eco-contribution and shouldering producer responsibility in terms of EU legislation. The result is that while, on paper, the WEEE Directive in Malta has been transposed, in practice its implementation is being obstructed. It is an area of responsibility that EU legislation assigns specifically to the private sector, yet the government is reluctant to lose a substantial chunk of eco-contribution revenues and is consequently applying the brakes.

The regulation of scrap yards does not feature in the update. They are required in order to recycle scrap metal. However, they should operate within a regulatory framework, in particular in conformity to the WEEE and the ELV (End of Life Vehicle) Directives. Recently, it was reported that, during testimony submitted in a planning appeal, concerning the enforcement order relative to the Ta’ Brolli scrap yard in Birzebbuga, it was revealed that part of its business originates from the custom of government departments and corporations!

Some scrap yards process scrap from disused refrigerators! Processing? They just crush them, as a result releasing refrigeration gases to air. These gases are CFCs (chloroflorocarbons), contributors to the depletion of the ozone layer. In a regulated environment in terms of the WEEE Directive, processing disused refrigerators for waste would include the careful collection of the CFCs as a first step. Instead, some Maltese scrap yards are contributing to the depletion of the ozone layer in contrast to the provisions of the 1987 Montreal Protocol, which Malta has bound itself to observe and implement.

The proposal for an updated strategy encourages a policy favouring waste incineration. It proposes that the use of bio-digestion to convert waste to energy is complemented by a policy favouring incineration. Specifically, it proposes a waste to energy incinerator to be sited at Delimara next to the power station. This could also mean that on waste recovery sites (currently in operation or projected) the two technologies could co-exist.

Incineration is undoubtedly a waste management tool. In my opinion, it should however, only be used as the last option.

Relying on incineration to produce electricity would, on the plus side, reduce required landfill space and the fuel bill. It would still, however, contribute to the production of greenhouse gases and, hence, cannot be described as a source of clean energy. On the minus side, it negates the need to reduce waste generation and produces other possibly toxic emissions, which would vary dependent on the composition of the RDF (refuse derived fuel).

The regulation of these emissions is normally established through a permit issued by Mepa in terms of the EU Directive on Integrated Pollution Prevention and Control. The acceptability or otherwise of an incineration facility even as a tool of the last resort would in my view result from two points: The quality of emissions control imposed by Mepa through the conditions established in the IPPC permit, and the enforceability of these conditions.

If the manner in which the Marsa incinerator has operated in the past months is a reliable indicator on the workings of Mepa and Wasteserv, this is sufficient on its own to discard the incinerator option even as a tool of last resort.

These are just a few of the points indicating reasons as to why the proposed waste strategy update needs to go back to the drawing board. Together with the fact that a Strategic Environmental Assessment has not to date been carried out, this is clear evidence of its poor quality. Such a document cannot lead to a fruitful public discussion.
