From Waste to Resource: Natural Fertilizer

The primary objective of the team was to develop a natural fertilizer for soil by recycling organic waste, addressing the significant issue of solid waste in Quetta, which generates approximately 1,500 tons daily, with around 40% being organic. This organic waste typically ends up in landfills, causing pollution, harmful gas emissions, and health issues, while occupying valuable land space in the valley. To combat this, the team focused on vermicomposting organic waste using red wiggler worms, a method that is more efficient than traditional composting and helps remove heavy metals linked to serious health conditions like cancer and Alzheimer’s disease. Despite the lack of large-scale composting solutions in Quetta, raising awareness about vermicomposting can greatly enhance soil health and significantly reduce greenhouse gas emissions by separating organic waste from other solid waste, thereby mitigating environmental pollution.

The initiative has led to canteens beginning to segregate organic waste, which plays a crucial role in revitalizing weak or under-fertilized soil through the use of compost. This compost is free from harmful chemicals, ensuring that groundwater and natural water bodies remain safe from pollution. It has a long-lasting presence in the soil, remaining effective for up to 4 to 6 years while promoting the growth of beneficial microbes. In contrast to ammonia-based fertilizers that harm the environment, pollute drinking water, and contribute to eutrophication, this composting method offers a sustainable alternative. Quetta city has the potential to recycle up to 300 tons of organic waste into compost, helping to alleviate landfill space issues. Moreover, individuals can earn an income of 200 to 300 per kilogram of compost produced, contributing to local economies and reducing the incidence of diseases and harmful gases generated by waste.
