Summary: This study addresses the lack of sustainable and efficient waste management solutions for handling scattered dry leaves, which commonly accumulate in Technological University of the Philippines campus. These leaves, if left unmanaged, can cause clogged drainage systems, flooding, fire hazards, and increased maintenance demands, especially during dry and stormy seasons. Understanding this issue is crucial because conventional leaf disposal methods are labor-intensive, environmentally harmful, and energy dependent. The unmanaged leaf litter contributes to waterlogging, increases the risk of disease-carrying insects, and wastes potential organic material that could be repurposed into useful mulch. To provide a practical solution, w11e developed a solar-powered leaf shredding machine that shreds dried leaves and that this organic waste converts into mulch using renewable energy. The prototype was designed with locally available materials and consists of a 590- watt bifacial solar panel, a 12V 100Ah lead-acid battery, a 1 HP AC motor, and hardened steel blades. The researcher conducted tests to evaluate its shredding capacity, power efficiency, safety, and sustainability. The results show that the machine can process up to 10 kilograms of dried leaves and stems per hour and run continuously for four hours under optimal sunlight conditions. It successfully reduces leaf volume which is scattered, prevents drainage blockage, and promotes cleaner surroundings without relying on grid electricity. These findings suggest that solar-powered shredding technology is a feasible and environmentally responsible alternative to traditional methods. It provides a scalable solution that enhances campus sustainability, supports local environmental goals, and encourages broader adoption of renewable energy in waste management practices.

This study addresses the lack of sustainable and efficient waste management solutions for
handling scattered dry leaves, which commonly accumulate in Technological University of
the Philippines campus. These leaves, if left unmanaged, can cause clogged drainage
systems, flooding, fire hazards, and increased maintenance demands, especially during dry
and stormy seasons. Understanding this issue is crucial because conventional leaf disposal
methods are labor-intensive, environmentally harmful, and energy dependent. The
unmanaged leaf litter contributes to waterlogging, increases the risk of disease-carrying
insects, and wastes potential organic material that could be repurposed into useful mulch.
To provide a practical solution, w11e developed a solar-powered leaf shredding machine
that shreds dried leaves and that this organic waste converts into mulch using renewable
energy. The prototype was designed with locally available materials and consists of a 590-
watt bifacial solar panel, a 12V 100Ah lead-acid battery, a 1 HP AC motor, and hardened
steel blades. The researcher conducted tests to evaluate its shredding capacity, power
efficiency, safety, and sustainability. The results show that the machine can process up to
10 kilograms of dried leaves and stems per hour and run continuously for four hours under
optimal sunlight conditions. It successfully reduces leaf volume which is scattered,
prevents drainage blockage, and promotes cleaner surroundings without relying on grid
electricity. These findings suggest that solar-powered shredding technology is a feasible
and environmentally responsible alternative to traditional methods. It provides a scalable
solution that enhances campus sustainability, supports local environmental goals, and
encourages broader adoption of renewable energy in waste management practices.
