Collecting bottles

Partnering with neighboring communities
In our experience, we have found that neighboring communities (read: kids), especially in bigger towns with a larger and more consistent amount of post-consumer waste, are gladly willing to help with the bottle collection effort.
Encouraging participation
We have found that the drive to participate and help others is quite strong. Motivating students to collect and stuff bottles can be done through the excitement emanating from you and your community partners. At times, especially near the end of the bottle collection when people are tired and the newness of the activity has worn off, it may be necessary to provide an incentive structure of some form (a pizza party for the winning class or bonus points on a test for every bottle delivered). Be creative with your rewards, if you choose to use any. Make them fun and cleanly competitive games between schools, grades, classrooms, etc.
How many bottles does it take to build a school?
Regular Bottles ~600ml
As a general rule of thumb, your bottle school need will be somewhere around 50 bottles per square meter of wall space (assuming you are using 20 ounce/600ml bottles). For instance, if your school were a 3m x 3m room (without windows or a door) that was 3m tall you would need approximately 1,800 bottles.
This is how to work out the approximate number of bottles you will need:
3m wide x 3m tall = 9m2
9m2 x 4 walls = 36m2
36m2 x 50 bottles per m2 = 1,800 bottles
Larger bottles
1.5 L: 30 eco-bricks per m2
2 L: 30 eco-bricks per m2
3.5 L: 25 eco-bricks per m2
