In 2009, waste of more recent technologies (i.e. laptops and LCD-monitors) is still<br />
negligible, but it will rapidly become an important fraction of the e-waste flow, while<br />
CRT-monitors are decreasing from being more than half of the total stream in 2005 to<br />
almost nothing by 2020.<br />
Figure 7: Estimated composition of the annual computer waste generated in Colombia (in<br />
weight).<br />
A future e-waste management system should take into consideration this change of<br />
technology in the computer market that will be reflected in a changing composition of<br />
e-waste. <strong>This</strong> change is clearly shown in Figure 8, comparing the average<br />
composition of the computer waste stream in number of devices and weight between<br />
the years 20<strong>10</strong> and 2020.<br />
