Figure 8.4. The use <strong>of</strong> non-renewable energy for the whole system in different scenarios. The results are presented<br />
per total amount <strong>of</strong> solid waste produced during a year (amounts are presented in chapter 4).<br />
8.1.3 Global warming<br />
Results for global warming are shown in Figure 8.5 for the base scenario. Also in this case the<br />
order <strong>of</strong> preference is recycling is better than incineration which is better than landfilling for the<br />
paper and plastic materials. This result is fairly robust. It is valid for all plastic and paper<br />
