Towards the effective E-waste management in Bangladesh: a review.

Nowadays, the electrical and electronic products are a crucial commodity for different purposes of daily life and they are multiplying five times faster than human like mobile phones, which has reached zero to 7.2 billion in only three decades. A 5-10% yearly increase in the amount of used electrical and electronic equipment that are disposed of prudently can cause environmental hazards that have an aversive effect on human health, marine life, contamination of groundwater, and reduces soil's fertility. Management of this enormous influx of electrical and electronic waste is a challenge for developing countries like Bangladesh with barebones solid waste management infrastructure. Inadequacy of public awareness, policies and poor budget in the field of waste management are few of the key factors behind this delineating scenario. In this study, the picture electrical and electronic waste productions in Bangladesh along with the recent E-waste management systems have been presented comprehensively. Based on the study, it was concluded that most of the adapted E-waste management methods are conversational and detached from current technological capability. A set of sustainable E-waste management system has been suggested along with the challenges, which might appear during the implementation of these strategies. Successful implementation of these suggested systems would advance the quality of E-waste management in Bangladesh increasing the current 35% overall E-waste recycling rate and offer enormous energy from the waste.

Towards the effective plastic waste management in Bangladesh: a review.

The plastic-derived product, nowadays, becomes an indispensable commodity for different purposes. A huge amount of used plastic causes environmental hazards that turn in danger for marine life, reduces the fertility of soil, and contamination of ground water. Management of this enormous plastic waste is challenging in particular for developing countries like Bangladesh. Lack of facilities, infrastructure development, and insufficient budget for waste management are some of the prime causes of improper plastic management in Bangladesh. In this study, the route of plastic waste production and current plastic waste management system in Bangladesh have been reviewed extensively. It emerges that no technical and improved methods are adapted in the plastic management system. A set of the sustainable plastic management system has been proposed along with the challenges that would emerge during the implementation these strategies. Successful execution of the proposed systems would enhance the quality of plastic waste management in Bangladesh and offers enormous energy from waste.
