recycling and recovery and disposal. In Europe the waste hierarchy has five steps (Raina, 2010): Prevention Reuse Recycling Recovery, e.g. energy recovery Disposal The waste hierarchy has taken many forms over the past decade, but the basic concept has remained the cornerstone of most waste minimization strategies. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste (Raina, 2010; UNEP, 2007). The Waste Hierarchy Concept of waste impact minimization, by reducing quantity of wastes, reusing the waste with simple treatments and recycling the wastes by using it as raw material to produce same or modified products is usually referred to as “3R”. As can be seen in Figure 2.1 prevention (reduce) is the most desirable in order of hierarchy, followed by reuse and recycling the least desired or favoured option. Figure: 2.1: Waste Hierarchy (Raina, 2010) This concept is key to sustainable management of E-waste. Simply put the principle of 3R is for example, using resources with care can and will reduce the pace of
