inventory management and performance of smes in the manufacturing sector of harare - sciencedirect

The study assessed the inventory management (IM) strategies that are used by SMEs in the manufacturing sector of Harare, Zimbabwe. The study comprised of the population from Gleview complex, Siya So Mbare, Kuwadzana, Gazaland and Magaba industrial sites. Respondents were selected from the each of the companies which the researchers selected purposively. The study used qualitative research design which was descriptive in nature. The study also used purposive sampling technique. A sample used a sample size of 244 respondents. Data was collected from the questionnaires which were completed and received back. The research established that most SMEs use the Just-In-Time method of inventory management and do not have knowledge on the other computerized systems and methods. Since companies use JIT method, SMEs face challenges in the supply chain as they always have to make sure they have constant communication with their suppliers and also to reduce the time in which they receive materials. However, due to lack of computerized communication, they have to make orders when they are needed which would make delays to the customer. Due to the finding, the researchers concluded and also made request for further studies on specific areas which needed more time and clarity.

characterisation of raw sewage and performance assessment of primary settling tanks at firle sewage treatment works, harare, zimbabwe - sciencedirect

characterisation of raw sewage and performance assessment of primary settling tanks at firle sewage treatment works, harare, zimbabwe - sciencedirect

Plant performance assessment involves adjusting primary settling tank performance.The buffering capacity of Firle sewage needs monitoring.The treatability ratio COD/TP is 28 and TKN/COD is 0.04 at Firle works.Firle wastewater is 30% industrial and 70% domestic.20% of Zimbabwe 12.9million people leave in its capital city Harare.

The need for more stringent effluent discharge standards as prescribed by the Environmental Management Act 20:27 to protect the environment can be sustainably achieved with the aid of Activated Sludge Models. Thus, the researchers believe it is time to re-evaluate wastewater characteristics at Firle Sewage Treatment Works (STW) and make use of activated sludge simulators to address pollution challenges caused by the sewage plant. Therefore, this paper characterizes raw sewage and assesses settled and unsettled sewage in order to evaluate the performance of the primary treatment system and the suitability of the settled sewage for treatment by the subsequent Biological Nutrient Removal (BNR) system at Firle STW. Parameters studied included COD, BOD, TKN, TP, NH3, TSS, pH and Alkalinity. Composite samples were collected over a 9-day campaign period (27 June to 6 July 2012), hourly grab samples over 24hrs and composite samples on 6 March 2012 which were then analysed in the lab in accordance with Standard Methods for the Examination of Water and Wastewater to support the City of Harare 20042012 lab historical records. Concentrations for unsettled sewage in mg/L were COD (52732), BOD (29783) TKN (19.02.0), TP (183), NH3 (24.012.9), TSS (21957), while pH was 7.00 and Alkalinity 26636mg/L. For settled sewage the corresponding values in mg/L were COD (52215), BOD (324102), TKN (21.03.0), TP (19.02.0), NH3 (25.611.2), TSS (25066), while pH was 7.00 and Alkalinity 27117mg/L. The plant design values for raw sewage are COD (650mg/L), BOD (200mg/L), TKN (40mg/L) and TP (11mg/L). Thus, COD and nitrogen were within the plant design range while BOD and TP were higher. Treatability of sewage in BNR systems is often inferred from the levels of critical parameters and also the ratios of TKN/COD and COD/TP. The wastewater average settled COD/BOD, COD/TP and TKN/COD ratio were 1.70.5, 27.13.1 and 0.040.01 respectively and corresponding unsettled ratios were 1.80.5, 30.776.8 and 0.040 respectively. Thus, treatability by the 3-stage BNR system appears highly feasible for nitrogen and is likely to be complex for phosphorous. Fractionation of COD, TP and TN is recommended to appropriately advise further steps to optimise the plant operations.

biomimetic architecture: green building in zimbabwe modeled after termite mounds

biomimetic architecture: green building in zimbabwe modeled after termite mounds

Biomimicrys Cool Alternative: Eastgate Centre in Zimbabwe The Eastgate Centre in Harare, Zimbabwe, typifies the best of green architecture and ecologically sensitive adaptation. The countrys largest office and shopping complex is an architectural marvel in its use of biomimicry principles. The mid-rise building, designed by architect Mick Pearce in collaboration with Arup engineers, has no conventional air-conditioning or heating, yet stays regulated year round with dramatically less energy consumption using design methods inspired by indigenous Zimbabwean masonry and the self-cooling mounds of African termites!

Termites in Zimbabwe build gigantic mounds inside of which they farm a fungus that is their primary food source. The fungus must be kept at exactly 87 degrees F, while the temperatures outside range from 35 degrees F at night to 104 degrees F during the day. The termites achieve this remarkable feat by constantly opening and closing a series of heating and cooling vents throughout the mound over the course of the day. With a system of carefully adjusted convection currents, air is sucked in at the lower part of the mound, down into enclosures with muddy walls, and up through a channel to the peak of the termite mound. The industrious termites constantly dig new vents and plug up old ones in order to regulate the temperature.

The Eastgate Centre, largely made of concrete, has a ventilation system which operates in a similar way. Outside air that is drawn in is either warmed or cooled by the building mass depending on which is hotter, the building concrete or the air. It is then vented into the buildings floors and offices before exiting via chimneys at the top. The complex also consists of two buildings side by side that are separated by an open space that is covered by glass and open to the local breezes.

Air is continuously drawn from this open space by fans on the first floor. It is then pushed up vertical supply sections of ducts that are located in the central spine of each of the two buildings. The fresh air replaces stale air that rises and exits through exhaust ports in the ceilings of each floor. Ultimately it enters the exhaust section of the vertical ducts before it is flushed out of the building through chimneys.

The Eastgate Centre uses less than 10% of the energy of a conventional building its size. These efficiencies translate directly to the bottom line: Eastgates owners have saved $3.5 million alone because of an air-conditioning system that did not have to be implemented. Outside of being eco-efficient and better for the environment, these savings also trickle down to the tenants whose rents are 20 percent lower than those of occupants in the surrounding buildings.

Who would have guessed that the replication of designs created by termites would not only provide for a sound climate control solution but also be the most cost-effective way for humans to function in an otherwise challenging context?

[] Eastgate Centre in Harare, Zimbabwehas no conventional air-conditioning or cooling; it is built with large chimneys that naturally draw in cool air at night. This cold air is then funneled through a system of vents throughout the building that lowers the temperature of the concrete floor slabs, which retain their coolness during the heat of the day. []

Good design. But there were other designs in the world which does not require air conditioning. Termite-Inspired Air Conditioning: Termite mound. Architect Mick Pearce collaborated with engineers at Arup Associates to build a mid-rise building in Harare, Zimbabwe that has no air-conditioning, yet stays cool thanks to a termite-inspired ventilation system. The Eastgate building is modeled on the self-cooling mounds of Macrotermes michaelseni, termites that maintain the temperature inside their nest to within one degree of 31 C, day and night, - while the external temperature varies between 3 C and 42 C. Eastgate uses only 10 percent of the energy of a conventional building its size, saved 3.5 million in air conditioning costs in the first five years, and has rents that are 20% lower than a newer building next door. In India( and in many Sunbelt Developing countries) Traditional mud houses are best examples of energy conservation. There is a saying," Well water, Brick house and Banyan Tree shade are warmer in winter and cooler in summer. Recently a complete mud house was built near Nellore at Pallipadu,Andhra Pradesh,India which uses mud and only columns concrete and steel. In some places people use Bamboo screens instead of metal mesh for building Almairahs. The tensile strength of bamboo is equal to that of steel. There is so much wisdom in traditional building construction which when blended with modern techniques will pave the way for energy efficient buildings. Our approach should be, MODERNISE THE TRADITIONAL - TRADITIONALISE THE MODERN. Dr.A.Jagadeesh Nellore (AP), India E-mail: [emailprotected]

This is a positive from zimbabwes highly developed education system which ironically mainly developed thanks to Mugabe(thats besides the point anywhere) The literacy rates in Zimbabwe compare with those of developed countries i.e they are over90%. Maybe thats what most europeans dont like about Mugabe sorry to wander off topic but its a great design ipso facto no need to digress

[...] Eastgate Centre in Harare, Zimbabwe is one of the largest and most elaborate examples of biomimicry around. This building, designed by architect Mick Pearce in conjunction with engineers at Arup Associates, does not require conventional heating or air-conditioning. The buildings design utilizes principles found in African termite mounds to regulate its interior temperature while dramatically reducing energy consumption. [...]

To add on the above post, Mick Pearce took a couple of my students under his tutorship, in his well established practice for their internship in the .year out, and they are established archittects themselves today - unlike some european led practces, I wont mention by names @ the moment who would'nt even offer opportunities to the likes of myself with years of vast architectural experience in the UK, both academic and works. I qualified in 1987 from one of the best schools Oxford Brookes in both Architecture & Urban Design. For those out there who still hold this backward myopic views that nothing good can come out of Africa, I urge you to take the blinkers off and be more progressive. Its the same with Renweables, Africa offers the most resourceful natural ingredients SUN, Wind, Water - name it, but what do you offer as Professionals??? If its politics you are interested in this is not the appropriate FORUM for it. Let progressive and innovatives have a chance to share.

To those who have been humble enough to leave positive comments about such an innovative biomimicry green design I say thank you and good for you. I was in Zim from 1998 where I ended up helping pioneer the 1st School of Architecture with a contingent of 14 students (13m + 1f). The school organised study visit of around 6 magnificently designed 'GREEN' bldngs in the capital of Harare and Mick Pearce's was top of the list. My students learnt more about 'Sustainable' Design compared to some, on that day. Mick conducted the tour himself complete with slide show...Dont denigrate progress for the sake 'politics'. Reminicent of the same old 'eurocentric' attitude towards 'Great Zimbabwe' (couldnt have been biult by Africans??????

[...] Biomimicry - or designs based on natural systems - is one of the most intriguing methods for designers and engineers to create innovative and efficient solutions to problems. Inspired by forms and functions found in nature, this approach to sustainable design allows for environmentally friendly solutions for energy, waste reduction and a bevy of other design challenges. Using biomimicry as the guiding design principle, the Australian firm BioPower Systems has developed Biowave: an ocean power system that harnesses energy by mimicking the motion of underwater plants in the ocean currents to generate electricity. [...]

I am glad that architects are looking to alternative solutions to design problems that can save the earth for disaster, and I am glad the alternative methods are functional and cheaper. With many more projects like this, maybe we just might survive...

I've spent time in this building (I'm from Zimbabwe) - it is quite beautiful and I recall being very excited when it was built. It's true that Mugabe has lead Zim to the edge of the abyss, but pls remember that Zimbabwe was in a period of economic growth & prosperity when this building was constructed. It was a real celebration of innovative design and reflected the extraordinary intellectual capital that had grown in Zimbabwe - hence the location is neither ironic or 'disgusting' within the context of the era in which it was completed. Now the once bustling shopping mall is largely empty - the 'ants' have left for greener pastures ! Anyone interested in termites & their extraordinary social structure should read a wonderful book by the South African Naturalist, Eugene Marais, titled, 'The Soul of the White Ant'.

Heartbreakingly ironic location for such forward-thinking ideas as even now, prime minister Mugabe purposefully drives his own people into starvation and trains children to kill ( If you follow the money, you find the client that commissioned this amazing building is City Centre Properties (Pvt) Ltd, which is owned by Old Main. Old Main, a financial company, is named along with Barclays and others as having provided loans to keep Mugabe's regime alive, e.g.,,2000349,00.html#article_continue. Even the architect of this brilliant project (who has designed many buildings in Zimbabwe) has to work outside of Zimbabe because of the political climate: 1-3916/pC/1 6-5167/ (interview with architect)

Termites are amazing and very successfull at living lightly in large communities. Not sure but their maybe more termites/ant on the earth than humans in biomass! This principle of biomimicry was also used in the design for CH2 in Melbourne - check it out - Also the principle architect was South African?

I am NOT surprised that this ingenious knowledge could and does come from African countries like Zimbabwe, there are some incredibly talented people in Africa. And yes they are STARVING AND DYING in Zimbabwe... so hearing about a brilliantly designed SHOPPING MALL, is really ironic and disgusting.

Really cool idea! Who knew termites were such ingenious little buggers. I think the idea of cooling tubes has been used before, but I have never seen it used to this degree. Simply amazing! AlienFarmer

Eastgate was built sometime in the early 1990s. When I lived in Harare (in the late 90s) it was full of offices and shops, and did indeed stay quite cool. Also, it had a killer deli on the second floor with really great salads.

Based on the description - Wicked cool! Cooling tubes and other ideas like this have been around for a long time, but it seems like this is a project that actually managed to make it functional and practical for its locale. Nice!

I'm not at all surprised that we can learn from the Termites, though of course there is a wild beauty to their own brainless skills. I am very surprised that the first place to utilize this knowledge is Zimbabwe, most of whose inhabitants are, from what I hear, on the brink of starvation.
