Abstract This paper estimates the environmental impacts and damage costs ('external costs') of synthetic nitrogen fertilizer discusses options for reducing these impacts, including their consequences farmers producers fertilizer. The life cycle that could be estimated are large, about 0.3 [euro]/kgN (compared to current market price 0.5 [euro]/kgN); much is due global warming by N2O CO2 emissions during production from fertilized fields. Policy internalizing discussed, reduced input on crop...
Summary This work aims to contribute the number of urban metabolism case studies using a standardized methodology. An economy‐wide material flow analysis (EW‐MFA) was conducted on Metropolitan Municipality Cape Town (South Africa) for year 2013, Eurostat framework. The study provides insights into city's through various indicators including direct input (DMI), domestic consumption (DMC), and output (DMO), among others. In order report uncertainty data, set data quality originating from life...
A major limitation to improved waste management in South Africa lies the paucity of reliable data and exclusion contribution informal sector from reporting. Due disparity provision formal services across households Africa, omission quantified practices leads an inaccurate representation existing repositories. Given potentially adverse social environmental consequences unregulated practices, a lack thereof has potential underestimate impacts. As 2015, 31% are reported as lacking basic refuse...
Abstract Sub‐Saharan African countries are well‐suited for the biogas digester technology because of their warm climates and availability animal manure. This could serve as a means to overcome energy poverty, which poses constant barrier economic development in Africa. A generative type capital cost estimation based on knowledge flowsheet major equipment, can be used by investors indicate magnitude proposed investment help provide other information, including profitability project, was...
Life cycle assessment has been used to investigate the global warming potential (GWP) and fossil-energy requirements of production biodiesel from canola (oilseed rape), soybean, sunflower oils in South Africa. The effect scale transportation raw materials products was investigated, as well ploughing grassland using irrigation grow oil crops. This research shows that GWP produced Africa vary widely, depending upon predominantly crop yield, requirement for irrigation, uncultivated land. For...
Construction and demolition (C&D) waste is generated from the construction, renovation, repair of built environment. It one largest streams generally not well documented or understood. Various methods for estimating C&D are reviewed, development two quantities composition in South Africa discussed. The lifetime method based on current production key construction materials their typical stock life. This contrasted with scale-up a pocket reasonably good statistics Cape Town’s...
