About Best Out of Waste
Best-out-of-waste projects turn plastic bottles, cardboard, CDs, old motors and household scrap into working models: a wind turbine from bottles, a hydraulic lift from syringes and cardboard, drip irrigation from a bottle, a water filter from sand and gravel, a periscope from a box and two mirrors. Schools often set them as competition topics, and waste management is a common science exhibition theme.

Building your own
- Choose one concept the model must show: energy conversion, filtration, pressure or irrigation.
- Collect clean, dry waste; wash bottles and remove labels so the model looks tidy.
- Add one working part, such as a motor, a pump or a light, so the judges see it in action. Components and Spares has the parts.
- Write a short card: what waste was used, what the model shows, and how the idea helps the environment.
