|Abstract: ||Leather sector in Ethiopia is the most focused area as a development reinforcing component.
The sector is also known for its intensive environment polluting practices. The intensity of
wastewater management problems calls for immediate solution in a tanning industry to maintain
community wellbeing and sustain development. Tanning process of Batu tannery employs large
amount of water and toxic chemicals generating large volume of wastewater mismanaged and
discharged in to little Akaki River nearby.
Improving tannery wastewater management and consequently reduce adverse environmental
impacts thus identifying the pollution alleviating techniques employed in tanneries and showing
environmental policy compliance gaps is the core essence of this study. Linkage and integration
of the individual production process management and respective wastewater management is also
To answer the research questions concerning wastewater management efficiency, pollution load
reduction techniques used and individual production process linkage with wastewater
management practices of Batu tannery questionnaires were distributed in the factory on the
bases of stratified sampling among four groups of workers and analyzed. Environmental adverse
impact and policy compliance gaps related to tannery wastewater management is shown from
information extracted through key informant response analysis and focus group discussion made
among tannery wastewater recipient community for further evidence conformation.
The study result revealed that, BTPLC tannery wastewater management lacks efficiency though
there is a planned ambition and vision to respond to the modern environment and quality
management systems. The result also indicated that individual production process management
lacks systematized, consistent and integrated linkage with the wastewater management.
Pollution reduction strategies involve very limited preventive waste management approach.
Tannery process water and chemical consumption is inadequately controlled and wastewater
treatment plant operational efficiency is inadequate. The study indicated that stakeholder
intervention is needed in Batu tannery in areas of EMS installment, monitoring and evaluation,
training, awareness creation, technology transfer and sounding regulatory system enrichment.
Most of the policy issues related to tannery wastewater management problems are unclear and
their compliance is limited. The finding showed that there is a gap in implementing environment
policy related to wastewater management in Batu tannery. Government bodies responsible to
enforce environmental policies are institutionally inadequate in this respect .The study also
indicated that efforts to assess adverse environment impacts of the tannery waste management
practices lack clarity and stakeholder commitment. Findings of this study also showed that the
role of EIA in a leather sector, as an environmental management and decision making tool
regarding overall effects of tannery wastewater in sustaining development is reluctantly
implemented and involve limited public participation.|
