New technologies such as gasification are currently being developed which will provide even more heat and power from our residual waste and they promise to be far cleaner than the mass burn incinerators on the continent, yet opposition remains strong. 'Costing the Earth' hears from local residents who fear the health implications if dioxins formed in the high temperatures are released. Environmental campaigners argue that even if the health risks can be addressed this solution only creates more carbon dioxide emissions when what we really need is more recycling and less initial waste. In his film 'Trashed' actor Jeremy Irons looks at how our waste affects our health and that of the planet. Tom asks if it's time for a national strategy on what goes into our bins and where our rubbish ends up.
