Here's what we discussed:

Composting

• What do we use? Bins or plot out an area in the school? If we use bins, it may be expensive unless we make our own. Plotting out an area is cheaper but it may stink up the whole place. The feasibility of each idea requires research and some consideration, but the current opinion of the group is to use compost bins.
  
  
• What will the cost of materials needed if we were to implement either of the approaches above? Compost bins available for purchase cost $200+. A more economical way would be to make our own compost bins from recycled materials, and then use them for making compost.
  
  
• How are we to reduce the amount of food waste that is produced by our school? Composting would only be so useful if nothing is done to tackle the root of the problem. This would have to fall back to our idea on publicity - besides raising awareness on climate change, we will also need to encourage students to not waste food.

Reducing energy consumption

• What are the approaches we need to take in assessing the school's energy consumption? Besides obtaining the school's total electrical usage logs, what else could be done to identify areas where electrical consumption can be reduced? Besides conducting surveys with cleaners to find out about electrical consumption of air-conditioning, we could also try conducting audits on the usage of facilities such as computers (e.g. how long the computers are left on and not in use).
  
  
• Since our school is already using energy-efficient appliances at places used often by students (for instance fluorescent lamps in the library and canteen), what else can be done to cut down on the electrical usage of the school? We decided to carry on with the green audit to find out which areas need to be improved upon.

Regenerating electricity from certain areas in the school

• What would be the cost of implementing such solutions in our school? Is it sustainable in the long run? This question was raised when the idea on generating electricity from lift shafts was brought up. The cost of building a generator in the lift shaft would be gargantuan, bringing the question of whether it would be effective in cutting the cost of electricity consumed by the school. The cost of implementing such a solution would only be short-term, but the savings induced would be able to counteract this.

Publicity

• We could organize an Earth Week, where talks, exhibitions and plays on climate change can take place. Reducing electrical consumption at the class level would also be encouraged during the week.
  
  
• The industrial visits could help us in coming up with new ideas for the project (especially the Singapore Mint).
