Which is more environmentally sound: recycled content or compostable?
Posted by Luke on January 23, 2010
There was a great article in a recent Resource Recycling issue that evaluates the pros and cons of recycled content vs renewable/compostable. This is a growing debate with foodservice operators and one that will surely continue for some time. With the growth of both products made from recycled content and products made from renewable resources, restaurant owners now have a couple of great alternatives to petroleum-based products based on their waste management systems.
Benefits of renewable-resource based compostable products:
When looking at the life cycle analyses of bioplastic resin such as NatureWorks Ingeo PLA, there’s no question that PLA releases fewer greenhouse gases during production than its petrochemical counterparts like PET. There’s also the key benefits of being produced from plants instead of oil and its ability to be turned back into dirt if disposed of properly in a commercial composting facility. Some argue that PLA takes away from our food source, but I have never been able to agree them. The corn used to produce PLA is grain corn, not the type of corn we eat on the table. And if the NatureWorks factory was at full capacity, which it isn’t, it would only consume .1% of the nation’s grain corn. Another argument anti-PLA people use is that PLA is made from GMO corn, which it is. Although I’m not a fan of GMO myself, I’d much rather use a GMO plant to produce a plastic cup than use oil imported from who knows where.
Benefits of recycled content:
Recycled content creates an interesting alternative and one that I believe is a 2nd best option to renewable resource-based products. Making cups from recycled content supports the recycling market which, ideally, in turn will build demand for more recycled products and more recycling. Building the demand for recycled products is important because if recyclers can’t find a channel to sell their recovered materials, they’ll be less likely to collect certain types of materials and will ultimately drive up the price for recycled content.
So between the two – recycled content and renewable/compostable – we now have two great options outside of virgin petrochemical-based products. What’s great about these options is that people can choose what works best for them. If they have access to a composting facility, renewable/compostable products are the most environmental choice. If they don’t have access to such a facility, recycled content products are a good alternative.
