Here’s a reminder to all BlueVary users: collect your used cartridges and send them for (proper) recycling. 
We’re doing our best to keep the effort required on your part to a minimum, but we rely on your cooperation. 
How can you recycle? Visit the recycling page and fill out the safety declaration form. By doing so, you confirm that the cartridges have not come into contact with hazardous substances, etc., and help protecting our employees. Once we receive the form, our customer service team will contact you to arrange pickup. All you have to do is pack the cartridges and provide us with the exact pickup location. Environmental protection can be that simple.
