Plastic bottles are not trash. When recyclable materials, like PET, are sent to landfill, they become completely useless. Keep them out of the waste stream by recycling them. Check for local NGOs, Residents Associations, schools and shopping centres that offer recycling services.
PETCO Kenya has provided drop-off sites located within some large shopping malls in Nairobi. Click on the links below for directions:
