Composting of Household Organic Waste

RESULTS

• House hold waste decreased to 90% of the total volume, in which final compost was dark brown, crumbly, and odourless.
• The study shows the use of this compost in comparison to soil without compost showed better growth and greener leaves for plants in the school kitchen garden.

DISCUSSION

Previous studies show Vermicomposting is an effective, low-cost, and eco-friendly method to manage household organic waste (1,2,4). The use of earthworms accelerates the decomposition process and produces compost rich in essential nutrients like nitrogen, phosphorus, and potassium (6). Advantage of this compost are

1. improves soil structure,
2. increases water retention, and
3. supports healthy plant growth (5).

This method can easily be adopted or scaled at home, schools, and communities to promote waste reduction and sustainable gardening (7).

CONCLUSION

My study proved that small-scale vermicomposting is a practical and beneficial method for managing household waste. It not only reduces waste volume but also produces high-quality organic manure, promoting environmental conservation and sustainable living.

ACKNOWLEDGMENT

I sincerely thank my teachers and parents for their continuous guidance, encouragement, and support throughout this project.
