Bio-bin: A commendable step towards sustainable waste

The initiative to set up a Bio-bin at the department of Botany & Zoology is a commendable step towards sustainable waste management within the college premises. This bio-composting system aims to convert food waste into useful compost, thereby addressing the challenge of food waste disposal.

The apparatus, consisting of three aerobic buckets arranged vertically with airtight lids in between, demonstrates a thoughtful design. The bottom-most lid, designed to hold water and inverted to prevent ant entry, reflects attention to detail in managing potential challenges associated with composting. Ants are often attracted to food waste, and by creating a barrier with an inverted lid filled with water, the bio-bin aims to deter their entry.

The inclusion of coir pith as an inoculum to accompany each lot of food waste is a strategic move. Coir pith not only aids in the absorption of excess water but also contributes to the composting process by providing a suitable medium for microbial activity. This addition helps balance the composting environment and ensures optimal conditions for decomposition.

The rotation of the buckets once the topmost is filled to capacity is a practical approach to continuous composting. This method allows for a systematic and efficient composting process, ensuring that the decomposition of food waste is ongoing. The anticipation of obtaining complete bio-compost within 45 days is an optimistic and achievable goal, provided the monitoring and rotation processes are diligently maintained.

Assigning two students from each year (first to third year) to regularly monitor the bio-bin is an excellent example of involving students in practical, hands-on environmental initiatives. This not only educates them about waste management but also fosters a sense of responsibility towards sustainable practices. The success of this initiative could indeed serve as an effective solution to the food waste menace within the college, setting a positive example for other institutions to follow.

 Regular monitoring, proper rotation, and adherence to the established procedures will be crucial for the success of the Bio-bin project. If executed effectively, this initiative can significantly contribute to the reduction of food waste and the creation of valuable compost for the college's landscaping or agricultural needs.
