How can we improve plastic recycling ?

Hi everyone!
I am student in plastics engineering and am interested in plastics recycling.
As you probably know, the most popular drawback of plastic is that it’s very polluting. The problem is that so much people just throw up plastics scraps into nature, or put it in the ordinary bin, whereas plastic can be recycled. Nowadays, plastic recycling has been well improved and we should continue on that way.
So, I’m looking for ideas which could be developed to encourage people to sort plastic to recycle them in the most optimum way.
Thank you in advance for your responses.

  • Dec 18 2013: Thank you very much for starting this conversation Julie, it's great to see the different approaches being taken to this issue all over the world. Existing approaches that I favour are recycling bins alongisde rubbish bins in the street as well as the home, and the charge on bottles and cans which is refunded if you return the material.

    I am working on a project en ce moment on trying to incentivise better social responsibility and behaviour among households. The goal is to formulate an index of how a community performs on a number of variables - percentage of waste recycled, average electricity consumed per household, blood donations, charitable donations, and 3 others - which will allow communities to be ranked on a leaderboard based on how socially responsible they are. Top-performing communities will be rewarded with a periodic prize fund and/or discounts from service providers.

    It reflects my belief that a combination of awareness, 'peer pressure'/self-comparison, and financial incentives can improve recycling and other behaviours. A related concept in the utilities field might be of interest to you http://www.ted.com/talks/alex_laskey_how_behavioral_science_can_lower_your_energy_bill.html .

    Bonne chance avec vos études
