- Sustainability issues
- Sustainability is about meeting the needs and demands of society without depleting resources or harming natural cycles for future generations
- Effect on the enviroment
- Renewable materials
- Are grown from plants or animals
- 6 R's
- Reduce
- the amount of material used in manufacture
- Recycle
- the materials already used
- Re-use
- design for disassembly and recover materials from 'end of life' products
- Repair
- products that have broken rather than replacing them
- Refuse
- to accept unethical or wasteful designs
- Re-think
- our attitude to enviromental impact
- Reduce
- Non-renewable materials
- Are taken from oil, ores and minerals, and can't be replaced (they are finite)
- Renewable materials
- Recycling / Disposing of Products
- Products and packaging have symbols on them to show...
- if they can be recycled
- the percentage of recyclable material used
- the materials they are made from, e.g. the type of plastic polymer used
- if a fee has been paid to recover packaging (the Green Dot symbol used in many European countries)
- materials that can be sorted and separated for recycling
- products that can't be disposed of in normal household bins, e.g. electrical products and batteries
- Products and packaging have symbols on them to show...
- Re-using Materials
- This reduces the amount of processing needed, so it's cheaper and more environmentally friendly.
- Examples of re-using materials include..
- refilling plastic or glass containers
- re-using car parts
- re-using clothing / shoes
- Examples of re-using materials include..
- This reduces the amount of processing needed, so it's cheaper and more environmentally friendly.
- Carbon Footprint and Product Miles
- A carbon footprint is the amount of carbon produced by any human activity and its effects on the environment. It's measured in units of carbon dioxide
- So, every activity you undertake and every product you use can be measured in terms of the...
- amount of energy used at every stage
- the carbon emissions produced
- So, every activity you undertake and every product you use can be measured in terms of the...
- Product miles are the number of miles a product travels in its lifetime. For example, a typical product might travel as follows:
- Source material to the primary processor
- material to the factory
- product to the distributor
- Distributor to the retail outlet
- Retail outlet to the user's home
- From home to recycling or tip.

- A carbon footprint is the amount of carbon produced by any human activity and its effects on the environment. It's measured in units of carbon dioxide
- Product Life Cycles
- Approximately 90% of oil is burned as heating and transport fuel.
- About 7% of oil is used to manufacture plastics
- Many plastics can be recycled. they need to be collected and sorted into their different types.
- Once sorted, the plastics can be granulated and cleaned to remove any impurities
- The recycled plastics are melted and extruded into pellets
- The pellets can be mixed with virgin plastic and moulded into new products.
- The recycled plastics are melted and extruded into pellets
- Once sorted, the plastics can be granulated and cleaned to remove any impurities
- Some plastics are dumped in landfill sites.
- Some plastics are burned, which causes toxic fumes to be released into the atmosphere.
