Edexcel IAL Chemistry AS 5.8 Polymer disposal
Edexcel IAL Chemistry AS 5.8 Polymer disposal
State one benefit and limitation for each route, identify acidic or toxic combustion products and connect finely divided calcium hydroxide to neutralisation and surface area.
How this is tested
- Compare incineration and recycling through landfill volume, energy use and emissions.
- Explain calcium hydroxide scrubbing of acidic waste gases from incinerators.
- Suggest biodegradable polymers or reuse to reduce persistent polymer waste.
