Next to the financial compensation for the delivery of empty cartridges, the environment plays an important role as well. By using empty cartridges again for the production of new cartridges, the environmental waste is decreased considerably. Several substances/materials that are present in cartridges can be very "harmful" to the environment. By cleaning the cartridges in a safe and sensible way and making them suitable for recycling, the environment can be spared substantially. If we unite and all support recycling, the environmental problems could be solved and a cleaner future could be ensured.
