Andrew and the ambassadors listen as Tim Brake from Redvale Landfill and Energy Park answers another question on this morning's web conference. Image: LEARNZ.
A new part of the landfill under construction. What material is used to stop leachate leaking out of the bottom of the waste pile? Image: LEARNZ.
One of several pumps around the landfill that takes leachate away for disposal. Image: LEARNZ.
Leachate is pumped out to this facility that boils it off as steam using landfill gas. Image: LEARNZ.
This pond is where all the rainwater that runs off the top of the landfill is collected. Are there other ponds like this around the landfill? Image: LEARNZ.
Rainwater coming off the top of the landfill is tested to make sure it is clean enough before being released into the local stream. What sort of things might be tested for? Image: LEARNZ.
A well head, the top part of a well that goes through the waste pile as part of a pipe network collecting landfill gas. How is landfill gas made? Image: LEARNZ.
Compare this image with the one above and describe what the differences are that you can see. What do these diferences show? Image: LEARNZ.
The red engines are like big vacuum cleaner motors sucking all the gases out of the landfill. Image: LEARNZ.
These are the generators that use methane to run, which in turn produces electricity. How many homes do they power? Image: LEARNZ.
These big chimney are the flares. Excess gases are burnt here so nothing harmful enters the atmosphere. How hot do you think it needs to be? Image: LEARNZ.
A Waste Management truck being weighed on the weigh bridge before entering the landfill. It will also be weighed when leaving. Why is it weighed twice? Image: LEARNZ.
The current tips site where waste is offloaded before being compacted. What do you think the blower on the left is releasing into the air? Image: LEARNZ.
Looking out over the energy facility at Redvale Landfill. What is being produced there? Image: LEARNZ.
Sheep happily graze over rehabilitated landfill land. What else might an old landfill site be used for? Image: LEARNZ.
How might these tall fences help during windy conditions at the landfill? Image: LEARNZ.
Rainwater running down off the top of the landfill is collected in ponds, monitored and treated if necessary, before being released into the local stream. Image: LEARNZ.

Household wheelie bins - one for general waste and the other for recyclables. What system for recycling do you have in your town? Image: LEARNZ.
A random selection of waste that is about to be taken to the landfill. How many items can you find that could be recycled? Image: LEARNZ.
