Approach for assessing the influence of an Energy Recovery plant: A case study in Gipuzkoa (Basque Country, Spain)

Abstract

In the European Union, the escalating generation of waste, together with the difficulties in finding new places for its disposal, have led to choose for incineration as an alternative to the management of non-reusable or recyclable waste, recovering it and generating energy. The incineration of waste, however, generates a series of contaminants that have been associated with effects on human health and the environment. Several studies have analysed the impact produced by energy recovery plants, by comparing the concentration of pollutants both in air and in biological samples donated by the population living near and far from these facilities. A notable limitation in existing research is the scarcity of baseline data on dioxins, furans, and PCBs in air and in the general population prior to the plant ́s start of operations. Such data facilitates meaningful comparisons with post-start-up levels. This article delineates the methodology employed to assess the impact on air quality and public health resulting from the implementation of an energy recovery facility through an urban waste incineration (waste-to-energy plant) in Gipuzkoa, located in the Basque Country, Spain. This methodology includes the measurement of the levels of contaminants in air, the level of exposure of the population by measuring the body load of contaminants, and the concentrations in soil and locally produced food. Furthermore, the health status of the population has been evaluated in both the short and long term, as well as the assessment of the risk from exposure to air pollution.
