1. Air pollution would still be an issue since fossil fuel trucks that produce exhaust have to go pick up recyclable items and bring them back. Also, the recycling process itself produces a lot of pollutants from inside the factory.
2. Contamination is also a huge obstacle in the recycling industry. Sometimes there are errors with sorting through recyclable stuff and let's say, for example, a spray can gets mixed in with other types of recyclables; it can contaminate the new products.
3. Most plastics can not be recycled. There are about seven types of plastic that we find and encounter on a day to day life, but only two of those plastics are recyclable. What isn't recyclable will be collected, processed, sorted and then thrown into a landfill.
Hope this helps.
