Reducing air emissions from tanneries with tradable permits

Abstract

Purpose

Tanneries present heavy environmental impacts due to air emissions. Specific quality objectives are fixed by European Directives concerning air and, in particular, volatile organic compounds. The purpose of this paper is to present a proposal for the management of air emissions with a view to achieve quality standards in the Italy's largest tannery district by means of a tradable emissions permits (TEPs) system.

Design/methodology/approach

A methodological approach is presented and analysed. The proposed system is based on the “bubble” configuration, which appears to be an effective and feasible application based on the total maximum daily load criterion, supported by the air quality standards or the environmental risk assessment (ERA) procedure.

Findings

The TEP system favours technological improvements in the reduction of emissions. The system may not provide a solution to the unpleasant odours deriving from the tanneries, but its application supported by ERA will make it possible to define the admissible levels of air pollution and improve the general state of air quality.

Research limitations/implications

Although the study is not exhaustive and requires further investigation in the economic, legal, administrative and air pollution sectors, it does give the basic elements for a preliminary analysis. The evident lack of experimental data concerning weather and climatic features, intrinsic to exposure assessment, has been pointed out.

Originality/value

This study proposes a methodological pathway aimed at defining the system of tradable permits by verifying the existence and availability of the necessary data. The proposed TEP system can be extended to other homogeneous industrial districts with an appropriate selection of one or more critical parameters.
