Overview of electronic waste (e-waste) management practices and legislations, and their poor applications in the developing countries

Abstract: The developing countries are facing huge challenges in the management of electronic waste (e-waste) which are either internally generated or imported illegally as ‘used’ goods in an attempt to bridge the so-called ‘digital divide’. E-waste contains hazardous constituents that may negatively impact the environment and affect human health if not properly managed. In these countries, because of lack of adequate infrastructure to manage wastes safely, these wastes are buried, burnt in the open air or dumped into surface water bodies. Crude ‘backyard’ recycling practices, which are not efficient and are highly polluting are also used in material recovery activities. Most developed countries have in place legislation mandating electronic manufacturers and importers to take-back used electronic products at their end-of-life (EoL) based on the principle of extended producer responsibility (EPR). In this paper, we review the concept of EPR, and discuss selected frameworks. The aim has been to find a mid point for the implementation of even an ‘abridged’ form of EPR in the developing countries. Implementation of EPR in the developing countries has become necessary in the light of the present high level of trans-boundary movement of e-waste into the developing countries and the lack of basic or state-of-the-art recycling and waste disposal facilities. Change in attitude by governments, appropriate legislation dealing specifically with e-waste, control of electronic waste dumping, implementation of EPR and transfer of technology on sound recycling of e-waste are the key issues in effective management of e-waste in developing countries.

Energy policy for low carbon development in Nigeria: A LEAP model application

Abstract: This paper applied a scenario-based analysis to explore Nigeria's future energy demand, supply and associated GHG emissions from 2010 to 2040 using the Long-range Energy Alternative Planning (LEAP) model. The impact of different energy policies are analysed for the Nigerian energy system by considering four scenarios: the reference scenario (REF), the low-carbon moderate scenario (LCM), the low-carbon advanced scenario (LCA), and the green optimistic scenario (GO). By considering aggressive energy policies and strategies from LCM to LCA, and even more aggressive options in the GO scenario, we find that under the REF scenario energy demand is expected to reach 3,075 PJ and a corresponding increase in GHG emissions of 201.2 Mt Co2e by 2040. More aggressive policy intervention by the Nigerian government, as in the GO scenario, would lead to a decrease in energy demand (2,249 PJ) and GHG emissions (124.4 Mt Co2e) in 2040. A cost-benefit and energy system analysis were also carried out in the study.
