To keep up with the fast-paced era of fashion and trends, the textile and clothing (T&C) sector utilizes diverse methods to fulfill the expanding consumer needs. With the exceeding demand for textile goods, the fair share of environmental degradation is also rising due to the bulk waste produced by the textile and clothing factories. Bangladesh is analyzed in this research as a top textile maker to assess the effects of eco-gamification on buyers' behavior. Research in advanced nations shows how views on sustainability differ among different groups and places, and emphasizes the importance of specific studies in Bangladesh. We suggest combining gamification methods with a circular economy framework to motivate consumer interactions with businesses and consumers. This platform seeks to encourage sustainable practices including garment reuse and repair and recycling and offering them for reuse. Utilizing reward points for recycling or selling used products will encourage consumers to adopt sustainable habits and deliver real perks. The envisioned B2C2C economic framework intends to cut down on waste and lessen the use of resources to advance an environmentally friendly textile industry in Bangladesh. The platform rests on a decentralized framework to ensure the openness and security of transactions across blockchain technology. This model intends to alter purchasing patterns through excitement-generating rewards and build a more sustainable fashion landscape in Bangladesh and globally.
