At best, this material is trash. At worst, it will contaminate recyclables if not disposed of properly. Sometimes there are local markets for a material, and sometimes those markets disappear overnight. Prices fluctuate too, sometimes monthly, sometimes daily. Markets also vary by hauler.
Different haulers handle different materials.
Some haulers prefer to handle only materials on a long-term contract basis, and others handle materials on a spot market basis. These differences will affect price as well as the availability of markets. Talk to several recyclers and haulers to see who best fits your needs, and to find out about current market conditions. Your hauler can collect many materials that he will then sell to different markets. All you need to do is find a hauler who will provide the collection service you need at a price you can afford.
