We began by putting small sachets of plastics on the containers mixing them up with medium sized plastics. Our goal shifted from making eco-bricks to just stuffing plastic into the bottles. After about 3 weeks, we noticed that our trash output reduced significantly from using a big trash bag, down to just a big sando bag. If I were to guess, it would be about 50%-60% less in volume. As it turned out, we were throwing out a lot of plastic to begin with.
