Where we're working during this month? Here's a glimpse of our solutions:-

1. 50m3 at APT, a milk centre in Marondera (Complete, awaiting the initial feedstock loading). We are bringing biogas to reduce the centre's reliance on grid electricity and diesel standby power generators for milk chilling and processing.
2. Belsize, a commercial poultry project in Inyathi, Bulawayo (We are bringing in biogas to support poultry brooding at commercial scale) rwducing the farm's dependence on charcoal and wood for poultry brooding. Excavations and ground preparation are underway for a 100m3 biogas facility.

Bio-digester are a perfect solution for organic waste treatment. When applied to sewage, it is important to get the sizing done correctly, otherwise, the system will fail to produce the desired results. Here's how we do it here at GreenTEC Energy.

Waste-to-Energy Updates.

Greentec Energy is implementing the project, "Greening Zimbabwe's communal milk collection centres for a sustainable dairy industry," targeting milk collection centres and smallholder dairy farmers. These rely on unstable grid electricity, diesel, and LPG for milk chilling and processing. On the one hand, the risk of milk spoilage is high, driving production costs up while pushing profit margins to very low levels. On the other hand, dairy farmers generate large amounts of organic waste, which is substantially underutilized. Our intervention is helping this important sector of our economy to switch to biogas, thereby lowering the risk of milk spoilage, enhancing productivity, and helping smallholder farmers to earn more.

Today, we took advantage of a field day organized by Grasslands Research Station and Agro Prosperity Trust (APT) in Marondera to disseminate information about this project. Farmers and other stakeholders who attended had the opportunity to tour a fixed dome biogas plant under construction at APT Milk Centre.

Bio-digesters are the game-changer. Apart from the energy benefit, they are a perfect solution for organic dairy waste management. In a digester, a wide range of putrescible wastes are broken down into an inert, nutrient-rich organic fertilizer, which can be used to substitute chemical fertilizers. The water can be recycled easily, creating a closed-loop system where nothing is sent to waste.
With support from our technical and financial partners, we are building digesters for farmers in an easy, seamless, and hassle-free manner, which avoids the need for high upfront payments.

Will you share this message with a dairy farmer near you? Your efforts will help us to reach people who need bio-digesters the most- one farmer at a time.

It was an honor to host Agricultural Engineering students and lecturers from Chinhoyi University. The students came to Marondera last week to tour a selection of our biogas projects.

They had an opportunity to see probably the only functional floating drum biogas digester in Zimbabwe. This small biogas digester, installed in 2021 in an urban residential setting in Marondera, addresses one of the most difficult problems facing urban households in Zimbabwe: food waste disposal. The digester treats all the putrescible waste generated at home, producing biogas as an added benefit. This allows us to cut household waste generation by half, helping us delay the need to send our bin for emptying/collection by municipal crews by 2 weeks and ensuring any plastic waste generated at home is clean and easy to recycle.

The students also toured the biogas plant at Agro Prosperity Trust where with financial support from developmental partners USAID Tetra Tech (and soon EEP Africa), we are implementing a biogas programme for Milk Collection Centres (MCCs) to reduce energy costs for milk chilling and processing. MCCs rely on diesel or unstable grid electricity to chill and process milk. The costs associated with these options are high, unpredictable, and directly reduce margins while increasing spoilage risk. Our intervention is replacing diesel and grid electricity-powered equipment with biogas-powered equipment, thereby improving productivity, lowering costs, and enhancing the farmers' incomes.

Finally, the students toured Dudley Farm, where we installed a biogas system in 2021 to support cooking and refrigeration. It is amazing to imagine how much CO2 emissions we have helped Dudley Farm avoid by having biogas to power their deep freezer and cooker for all these years.

Despite these achievements, we acknowledge that our activities may unintentionally impact the environment negatively. As a gesture of goodwill to the environment, we donated a Loquat Tree seedling to the students, hoping that if they plant it at Chinhoyi University, that small step will help in our efforts to keep Zimbabwe green.
