A small beige house stands at the edge of a field, with two rows of solar panels on its roof gleaming under the sunlight. This “garbage-eating†house is designed to turn waste into something useful. It can process the daily garbage of 80 to 100 households and effectively digest 92% of biodegradable waste, according to Liu Laipo, head of the Armed Force Department in Sanlaipo Village, Liujing Town, Qingxiu District, Nanning.
The facility, which recently went into operation, cost a total of 146,000 yuan and marks the first solar-powered waste reduction station in Guangxi. It represents a new approach to managing rural waste, addressing a long-standing challenge that has affected many villages.
In the past, waste collection in Liuxiu Township was costly and inefficient. Sanlaipo used to clean and transport garbage once a week for 200 yuan. However, during the "Clean Country" campaign, Qingxiu District began exploring better waste management solutions and set up this solar waste treatment station as a pilot project.
The station includes sorting areas, a landfill for non-degradable waste, and a decomposing room. Each day, workers collect household waste from local homes and sort it into recyclables, non-degradable items, and organic waste. The organic portion is then fed into a tank where it is fermented using high-temperature solar energy, turning it into organic fertilizer. The system also uses activated carbon to absorb any odors. This technology allows for the effective degradation of 92% of biodegradable waste.
Recyclable materials are processed and reused, while only a small amount of non-organic waste is sent to the township landfill. As a result, operating costs have dropped by 80%, reducing both transportation and disposal expenses. This system helps achieve the goals of waste reduction, resource recovery, and minimizing environmental harm.
To encourage proper waste sorting, each household in Sanlaipo has been provided with three different trash bins labeled for recyclables, non-recyclables, and kitchen waste, along with educational flyers. As a result, most of the village’s waste is now handled locally, with very little non-organic waste needing to be transported elsewhere.
