Read moreSmart Organic Waste Segregation and Compost Quality Analyzer
ABSTRACT Organic waste (food scraps, yard waste, etc.) comprises the bulk of Kenya’s waste stream (about 70–80%). Unsegregated disposal causes large methane emissions and lost resources. This project designed a…
Read moreEco-Friendly Waste Oil Stove for Sustainable Heating
Abstract: This project designs and tests a low-cost, sustainable stove that burns recycled waste oil (used cooking or motor oil) for household heating. Waste vegetable oil has a high heating…
Read moreAdsorption of Lead and Copper Ions from Wastewater Using Thermally Modified Eggshell Calcium Oxide
AbstractHeavy metal contamination of water is a serious health and environmental concern. This project investigates a low-cost, sustainable method to remove lead (Pb²⁺) and copper (Cu²⁺) ions from contaminated water…
Read moreSmart Seed Viability Tester
Abstract Seed viability (germination potential) is critical for agriculture, especially for smallholder farmers and seed banks. Traditional viability tests (germination or tetrazolium staining) are accurate but slow, destructive or expensivepmc.ncbi.nlm.nih.govijoear.com.…
Read moreSMART GREENHOUSE USING CO₂ AND LIGHT OPTIMIZATION
Category: Applied Technology Abstract Increasing agricultural productivity under climate constraints is crucial for food security. A smart greenhouse automates control of key growth factors (CO₂ and light) using electronic sensors…
Read morePRODUCTION AND USE OF CACTUS LEATHER AS A SUSTAINABLE ALTERNATIVE TO ANIMAL LEATHER
ABSTRACT Cactus leather is a biodegradable, cruelty-free material derived from Opuntia cactus pads. In this study, cactus leaf mucilage was extracted, mixed with natural binders (cornstarch and glycerin), and cast…
Read moreMagnetic Water Treatment System for Improved Germination of Capsicum (Pepper) Seeds
Abstract This project describes building a simple magnetic water treatment device from PVC pipe and neodymium magnets, and testing its effect on the germination of capsicum (pepper) seeds. We built…
Read moreBio-Electrochemical Wetland Battery (Plant-Microbial Power Cell)
Abstract Wetland-based bio-electrochemical systems harness plant–microbe interactions to generate renewable electricity. This project built a small constructed wetland cell with aquatic plants and conductive electrodes to test if natural decomposition…
Read moreThermo-Syphon Solar Water Heater With Phase-Change Material Storage
Abstract A prototype solar water heater was built using a thermo-syphon (passive) loop and a phase-change material (PCM) reservoir. During sunny hours, rooftop solar collectors (evacuated glass tubes) heated the…
