Hi, I have started making my ecobricks with bottles of 1 litres and keep getting them rejected because of the weight.  Please could you tell me the right weight they should be for future reference????? I have four more plastic bottles this size to fill with my plastic, and don't want them to be rejected again. 


Kind Regards

Hi Stuart

Great to hear that you are making ecobricks! The minimum density is 0.33g/ml so your 1L bottles need to weigh at least 330g. Cutting your plastic into smaller pieces and alternating between soft and firmer plastics will help you get more into your bottle. 

Keep up the good work!
