An Ecobrick is a plastic bottle packed with used plastic to a set density to create a reusable building block. Ecobricks can be used to produce modular items, including furniture, garden walls and other structures. Ecobricks are produced primarily as a means of managing plastic waste by sequestering it and containing it safely, by terminally reducing the net surface area of the packed plastic to effectively secure the plastic from degrading into toxins and microplastics.

We, at Sumatra Dream Class, promote the personal ecobricking process as a means to raise awareness of the consequences of consumption and the dangers of plastic. We also promote the collaborative process as a means to encourage our community to take collective responsibility for our plastic waste and to use it to produce a useful product.

At English Class we introduce the children of our community to conservation and try to create awareness of “our” garbage problem. We also talk to the members of our community and try to encourage them to reduce the amount of plastic in and around our village. We introduce them to the ecobrick and teach them how to make an ecobrick. In return they receive the equivalent of 29 cents per ecobrick (enough money for a hot meal), at this point of time, this money is sponsored by Project Wings (

With the help of this deposit system, we hope to produce and collect 2000 Ecobricks, which than will be used to build a fence around the yard of our elementary school. This should help to keep out the animals such as cows and will create a safe and clean area for the kids to play in.

Let’s turn “our” plastic waste into Ecobricks and help us build a garden-wall around our schoolyard.

Thank you Project Wings for funding the Ecobrick Project in Porli!

Typically, people use a wood or bamboo stick to manually pack plastic into the plastic bottle. Any size of transparent PET plastic bottle can be used to make an Ecobrick. The bottle and the packed plastic are clean and dry to prevent the growth of bacteria. Plastic is cut or ripped into small pieces then packed little by little, alternating between adding the plastic and compacting it, layer by layer. The bottle is rotated with each press to ensure the plastic is evenly compacted throughout the bottle. This helps prevent voids and that the packing reaches the requisite solidity needed for a building block applications.
