The most natural way to handle greywater is through direct reuse. That is, the greywater is directly led to a living soil, where pollutants can be converted by micro and macrofauna. In this way, the water and nutrients are used to stimulate plant growth. It must be noted that greywater cannot be stored for long before taking on an odour and becoming a health hazard. However, the water may be treated and subsequently held in tanks for later non-potable use.
As shown in the figure below, the water is filtered through the mulch material and eventually flows towards a tree at the centre of the pit.
As the greywater reaches the surface of the mulch pit it should spread all over the surface instead of pooling in one spot. You could place an old plate on the surface of the mulch so that water coming from the pipe splashes outwards and is quite simply distributed.
You may occasionally have to remove particles that may be blocking the pipe and rearrange the mulch material with a shovel. If a layer of scum forms at the pipe outlet, you can remove it if you so choose. However, the scum will not adversely affect the effectiveness of the mulch pit since the water will simply flow over the layer of solidified scum and infiltrate at another location. Also, if there are many large food scraps present in the effluent, you may have to remove them to ensure that these particles do not block the pipe opening. In short, this system is easy to maintain.
AFRIKOA is the first bean-to-bar company in South Africa to produce chocolate made from cocoa sourced directly from African farmers. By trading directly with the farmers, Afrikoa ensures the freshest, finest-quality cocoa beans and empowers the farmers to create their own sustainable futures. Their cocoa beans never leave the continent, travelling just far enough to the southern tip of Africa, where their experienced chocolate-makers create the perfect chocolate bar.
While almost two thirds of the world’s cocoa is grown in Africa, most of it is exported to Europe and America where it is turned into chocolate before being returned to our African shores. Afrikoa believes in growing the art of chocolate-making within Africa and supporting the farmers and their local communities, which is why they have made a promise that their chocolate will always be made in Africa, for Africa, using cocoa beans that have never left the continent.
Afrikoa’s search for the best African cocoa beans led their Head Chocolate Maker, Antonino Allegra, to the small rural region of Kyela in Tanzania where he met two groups of passionate farmers headed by Castor Sanga and Simon Mwakyusa who were both frustrated with a system which left their hard work and excellent-quality cocoa beans with little reward. It was while sitting in a traditional meeting under the shade of a cocoa tree that Antonino realized the mutual benefit of simply buying the cocoa beans straight from these farmers.
Afrikoa believes that this partnership, which treats the farmers with fairness, dignity and respect, is the future of chocolate and one that also means you can enjoy their chocolate knowing that you are encouraging a sustainable future for these 60 farmers and their families.
Direct trade means that the cocoa beans are sourced directly from cocoa farmers, cutting out all the traditional middlemen, buyers, sellers and organisations that control certifications, all of whom add their own profit margins to the beans the farmers have worked so hard to grow. By trading directly with the farmers, Afrikoa ensures the finest-quality cocoa beans while the cocoa farmers earn 250% more than they would the traditional way.
Yet another benefit of direct trade is fresh cocoa; while the traditional cocoa bean trading system means that the majority of chocolate makers buy their cocoa from Europe, it also means that these cocoa beans sit in massive warehouses for months and lose valuable flavour. By trading directly with farmers, Afrikoa receives the cocoa beans within weeks of them leaving the farms in Kyela. Fresh cocoa beans are highly aromatic and packed with flavour and we believe that this is what makes AFRIKOA chocolate so unique.
Direct trade is certainly not the easiest route and Afrikoa have faced many challenges and gone to great lengths to do so successfully. While the process sounds simpler, removing all the middlemen also means removing traditional transport systems and starting from scratch. Often the best cocoa is grown off the beaten track and getting the cocoa beans from farmers in Kyela to the shipping port of Dar Es Salaam now requires a 12-hour journey by truck via dirt roads – a long trip that Castor and Simon take themselves in order to make sure their beans arrive safely and just one of the many examples of their passion and eagerness to empower themselves. At each step of the process, AFRIKOA provides them with support, knowledge and resources. While direct trade is a challenge very few chocolate makers undertake, Afrikoa believes in it because sometimes the right way isn’t always the easiest way.
