Estimates of weight of general refuse generated in this country’s major cities vary, but in Harare it is estimated at above 823 000 tonnes, which is mostly land-filled. This paper proposes the incineration of combustible municipal waste to produce 40 MW of electricity and considers its feasibility. This can give a waste reduction to as low as one tenth of the initial volume and is quite effective in killing pathogens. The work involved use of questionnaires, interviews and access to primary data at the Harare City Council. The positive and negative environmental and health impacts, particularly relating to dioxins are discussed and solutions to pollution proposed.

Analysis Technique

This study used a descriptive qualitative research method with the technique of determining informants by purposive sampling. The technique of data collection is done by collecting primary data (interviews and observations) and collecting secondary data (literature studies and documentation). While the data analysis technique uses qualitative data analysis techniques.The results of this study indicate that the current waste management strategy at the Kendari City Environment and Forestry Service is quite maximal in overcoming waste generation. This can be seen from the strategic planning carried out by the Kendari City Environment and Forestry Service in the implementation of being able to increase the waste reduction target in carrying out its vision and mission of realizing Kendari which is clean and beautiful. While for operational planning at the Kendari City Environment and Forestry Service, it is still not optimal, it is faced with a related obstacle, namely the lack of technical staff available in their respective fields. This lack of a workforce can result in increasing volumes of waste every day because the population is not proportional to the number of employees, especially workers who handle the waste.

Background: Health Impact Assessment (HIA) can be used to assess any type of policy/program related to social determinants (SDH).  However, local public health departments (LHDs) have been slow to adopt formal use of HIA in efforts to address local SDH, even with growing evidence linking SDH and place-health relationships. Ten years ago we completed a review of Baltimore City Council policies to advance this conversation within the LHD. Our goal here is to revisit this review and, again, outline a process by which LHDs can: a) monitor local policies in regard to SDH and b) identify opportunities for potential HIA use. Methods:  We reviewed all policies introduced into Baltimore City Council in calendar years 2008 and 2009. We reviewed each policy to identify those with potential health impacts. We then categorized these policies as: a) “explicitly health-related” or b) “related to SDH.” We then tabulated the number and sub-types of these policies that were referred for LHD review. Results: We identified and reviewed 597 total policies. 89 policies (15%) were identified as “explicitly health-related,” 34 (38%) of which were referred for LHD review. 208 policies (35%) were identified as “related to SDH,” 13 (6%) of which were reviewed. Overall, 297 (50%) policies were identified as having potential health impacts, 47 (16%) of which were reviewed. Conclusion: This work represents a potentially replicable process to identify HIA opportunities, and potential launch point for health-in-all-policies efforts. In Baltimore, it facilitated dialogue with Baltimore City officials and led to the LHD’s first HIA grant.

Monolith Catalyst

In this work, we set out to investigate the deactivation of a commercial V2O5-WO3/TiO2 monolith catalyst that operated for a total of 18,000 h in a selective catalytic reduction unit treating the exhaust gases of a municipal waste incinerator in a tail end configuration. Extensive physical and chemical characterization analyses were performed comparing results for fresh and aged catalyst samples. The nature of poisoning species was determined with regards to their impact on the DeNOx catalytic activity which was experimentally evaluated through catalytic tests in the temperature range 90–500 °C at a gas hourly space velocity of 100,000 h−1 (NO = NH3 = 400 ppmv, 6% O2). Two simple regeneration strategies were also investigated: thermal treatment under static air at 400–450 °C and water washing at room temperature. The effectiveness of each treatment was determined on the basis of its ability to remove specific poisoning compounds and to restore the original performance of the virgin catalyst.
