Clean your plastic bottles and fillings

Before you start filling your plastic bottles with plastic waste, make sure that both of them are washed and dried. The plastic used to fill the bottle must be free from the residue of its last contents and must be dry before you put inside. “Plastics that contain dirt and grime can cause microbiological growth and methane gas formation within your eco brick which can lead to an unsightly product or bloated bottles.”

Cut your non-biodegradable before filling your plastic bottles.

For eco bricks to work, it must be tightly-packed with plastic waste so it is better to cut the plastic that you will insert inside the bottle. This will help every item to fit every inch of the bottle. It is better to cut the soft plastic bigger and the hard plastic smaller.

Fill your plastic bottle

With your plastic materials, carefully fill up your clean plastic bottle and make sure that they are pushed closely and tightly together. You can use a stick to push the contents together and make sure that there are no spaces or air inside the bottle. Make sure that the bottle will not get damaged in the process of filling the insides. It is important for the bottle to be tightly packed because it must weigh the total volume of the bottle multiplied by 0.35.
