Making your wedding, meeting, or party into a zero-waste event can be a clear display of your stewardship for the environment as well as an educational experience for attendees. Done successfully, there are benefits for the environment including waste management (nothing goes to the landfill) and energy savings. However pulling it off is not as easy at it might seem. There are three questions to ask yourself when planning your zero-waste event.
First, can you use durable goods such as ceramics, silverware, glasses, and cloth tablecloths and napkins? If so, use them! This is often an option when events are held in churches or halls that have their own durables. Yes, there is some extra work since they need to be washed, but there will be much less trash to dispose or which will save you some money.
When durables aren't an option and you'd like to use compostable food service items, can you avoid contamination of compostables and/or recyclables? For example, can you instruct your attendees either verbally or through signage to separate out compostables, recyclables and any remaining trash? If not, you will likely end up with contaminated compostables and/or recyclables. Most people are not accustomed to this level of separating out their waste (yet!). Recycling has been around for a long time but even now at any given airport you'll find recyclables in the trash receptacles, so people are bound to make mistakes. These factors help avoid contamination:
• Only use compostables for the event.
• Instruct event attendees as a group as to how to dispose of their waste.
• Have someone present by receptacles to instruct attendees.
• Post very clear signage on waste receptacles.
Last, if you think you can avoid contamination of your compostables, do you have a place to compost your compostalbes? Check with your municipal waste facility to ask about drop-off composting options or commercial composting facilities in your area. You can also look for local composters at findacomposter.com. If there is a local commercial or municipal composting facility, be sure to ask which compostables they will accept. Many do not accept bioplastics.
Composting at home might be an option, but certified compostables are meant to be composted in commercial or municipal composting facilities where high temperatures and humidity are achieved. Most home composts do not achieve such conditions. Compostables made from paper and bagasse (residual from sugar cane) or other non-plastic compostables will likely break down more successfully in the home setting than compostable plastics, although information on home composting of bioplastics is lacking. Also consider the amount of compostables you will generate. If you have a family reunion for 50 people and a 3x3x3 foot bin, you will likely end up with an overflowing bin for a while.
Compostables require composting to fully break down and complete the biological cycle, but unfortunately not everyone has access to a commercial or municipal composting facility. Compostables can be used in areas where there are no composting facilities or home/farm composting options, but the benefits of using them are much less (if any). Bioplastics in landfills may last as long as traditional plastics, and landfilling them breaks the biological cycle that sustains us.
