Australian Post and our partner TerraCycle are now working together to recycle used mailing satchels with the launch of the Australia Post Mailing Satchel Brigade. Returning used mailing satchels to TerraCycle gives the satchels a second life, transforming them into useful new products including play equipment, wallets, bags and recycled plastic containers. The Lock Post Office will have a plastic bag recycling box at the Post Office. By dropping your bags into the Post Office, they will receive two cents per bag to donate to the school.
