- Description: Abstract: There is a need to introduce modern technologies to address inefficiencies in foundry engineering. The foundry industry is very old dating back as far as 1479. The early foundry engineers produced metal castings which were mainly cannons and bells. Foundries have been slow to adapt to disruptive technologies. However with the 4th industrial revolution foundries cannot afford to miss out. Foundry Engineering which is metal casting is under a lot of pressure from other competing manufacturing technologies. Forging, fabrications and 3D metal printing, plastic and composite materials are competitors to metal casting. The most common and cheapest way of producing castings is in greensand. This is due to the fact that it uses low cost raw materials. Though the process is cheaper than other casting processes. There is always a need for improving efficiencies in the means of production to compete with other manufacturing technologies. The 4th industrial revolution has become a pillar of improving competiveness in the metal casting process. This paper evaluates how the first cloud based green sand data analytic software Sandman plays a role in contributing towards the achievement of the sustainable development goals in African foundries. The greensand data analytic programme has been seen to be a key resource in driving for responsible consumption and production. This study will provide knowledge on the benefits of using a data analytic software in greensand moulding.

- Description: Abstract : Composting and AD of biodegradable waste were assessed for their benefits from literature and environmental impacts using the life cycle impact assessment procedure. Literature review findings indicate an overall edge for AD over composting largely due to its renewable energy production capabilities, reduced exhaust emissions and cost effectiveness considering the entire MSW life cycle. LCIA results show that both AD and composting leads to increases across the four impact categories considered namely, global warming, human health, eutrophication and acidification. AD however showed lower contributions than composting to global warming, human health and acidification. Composting only showed lower contribution than AD in regards to eutrophication. Overall study results indicate an edge for AD over composting in treating and managing biodegradable fraction of MSW generated in Harare and its surrounding urban and peri urban environments of Chitungwiza, Epworth, Norton and Ruwa.

- Description: Abstract: Many e-Government development models have been conceptualized based on a snapshot or current status of institutions and individuals (Agents) without considering the fact that agent statuses change over time. The implication of utilizing snapshot models to measure factors or frameworks influencing adoption or successful implementation of e-Government is that they capture what factors matter at a given point-in-time but do not look into the effect of those factors on e-Government after a period of time. This work proposes adoption of dynamic/agile development of e-Government solutions which stand a better chance of sustainability since dynamic changes in agent tastes and circumstances can determine which factors influence adoption and usage of e-Government in any given context. Understanding agile factors influencing e-Government adoption is important in designing adaptive e-Government models which are imperative for designing sustainable interventions for e-Government development...
