Born out of a love for providing their community with delicious, nutritious, and high-quality food, husband and wife duo Rajan and Priti Marwaha started Sai Energy & Logistics Services in Iringa, Tanzania. Established in 2014, Sai Energy and Logistics Services initially started as a bakery and then later diversified its product portfolio after realizing the potential demand for dairy products like mozzarella and ricotta cheeses, snacks like potato chips and cashew nuts, and other sweet treats.
After years of success in the market and gaining a deeper understanding of local and global consumer trends, Rajan and Priti noticed a need not yet being met locally. “After extensive research, we saw a window of opportunity in adding gluten-free products to our growing product portfolio,” said Rajan. “We learned that approximately 31.8% of Tanzania’s children under the age of 5 years are malnourished and 51.3% of children in our region of Iringa suffer from this. In addition to continuing to provide our current product portfolio of nutritious products, we wanted to develop new specialty breads and biscuits from gluten-free sweet potato flour to help solve the issue of malnutrition and create awareness of how to opt for living a better and healthy life.”
With limited knowledge in the development of gluten-free products, Sai Energy & Logistics Services enlisted the help of TechnoServe, USAID, and PFS to get them started. Joining the project team from Ardent Mills were Bakery Plant Manager Dewaine Schaecher and product developers Jerome Davis and Jacob Mattson. With 60+ combined years of experience in R&D and baked goods, these volunteers made the perfect team to help Sai Energy & Logistics Services bring their new product concept to life.
“Initially our team was a little hesitant in dealing with such highly experienced individuals on the project team,” said Rajan. “But by the end of the project, the transfer of knowledge, especially on the technology behind making these products, and the ease of communication between us and the project team became our favorite part of the project!” Rajan said that his team learned a lot from the Ardent Mills volunteers including how to measure the right proportion of ingredients, how to improve product shelf-life through monitoring pH levels of doughs, the right methods of mixing ingredients, and innovations and alterations of their existing methods.
Rajan said the gluten-free sweet potato project for biscuits has reached the final stage and has been accepted by consumers so they are now are developing strategies to upscale production. Additionally, the company is working on the product’s packaging design and they hope to launch the new product later this month.

Please share a little about yourself and your role at Cargill.
I work in the Growth Ventures team for Cargill Protein-North America (CPNA) where I am the Director of Emerging Products and Solutions. My role focuses on identifying, incubating, and commercializing new business opportunities in emerging spaces like carbon, digital, and e-commerce. I originally joined Cargill in 2017 straight out of business school with the corporate strategy team. I have also worked in digital innovation and startup partnerships for Cargill-Digital Foundry and in strategy/mergers & acquisitions for CPNA.
What was your main motivation for volunteering with PFS?
Two factors motivated my interest in PFS once the opportunity was presented. First, I studied international development in undergrad and studied abroad in South Africa where I had the opportunity to support community development through entrepreneurship in a township near Stellenbosch. PFS’ dedication to capacity-building in Africa felt like a spiritual continuation of this experience.
The second motivation was my fairly recent entry into Cargill via its corporate strategy team in 2017 (around when I joined PFS). I was new to both the functional role, strategy development, and food/ag, and saw volunteering with PFS as a development opportunity that would help me learn more about project management and the industry.
What is your favorite part of volunteering with PFS?
The two companies I have worked with (Kentaste and Full Spoon Limited) both operate in markets where Cargill has little or no presence (coconuts and peanuts, respectively), so it has been fun to learn more about both from the client company’s founders. In addition, both clients have needed help with food safety projects, which is a new functional space for me to learn at a high level.
What would you say to a colleague who is interested in volunteering with PFS, but hesitant to start?
Dive in! There are a lot of companies with projects that need the type of food/ag expertise companies like Cargill can provide.
