Earth Day 2005: — Moving Towards Zero Waste |
An example of the waste that |
Background Information
ImplementationThe Set Up and Bin Placement — In the past, all three events have recycled beverage containers, but the move to zero waste included separately collecting paper, food wastes, and other biodegradable discards for composting. In addition, waste reduction and minimization considerations were incorporated into other aspects of the event, such as food service, vendors' products, and event activities.
Though the serving ware looks like it is made of typical petroleum-based plastic, it is actually made from wheat, potato, and corn resins. Prior experience working with the biodegradable plastics has shown that they break down in the composting process after about 80 to 90 days. Event organizers also encouraged booth participants to keep handouts to a minimum, incorporate sign-up sheets for e-mail contact or mailing list additions, and to reduce the amount of garbage associated with samples and give a-ways. While all three events are held at different venues, the same zero waste plans were proposed for each event. This included providing three to four waste stations at various locations. These stations had separate receptacles for each of the three material types generated during the festivals -- organics, recyclables and trash. Signs and examples of proper and improper materials were displayed at each of the stations. Stations were placed in high traffic areas near the stage or main attraction, restrooms, food vendors, entrances, exits, and other well-traveled areas. Volunteers
Composting
Through NDEP support, compostable wastes were taken by Full Circle Compost of Minden, Nevada for composting. Full Circle Compost is a permitted full scale composting facility that uses an "Advanced Composting System". When the bags of compost arrive at Full Circle, woodchips are added to the compost and then the mixture is ground up in a tub grinder that shreds the compostable wastes in to small pieces (see picture below). After this, the compost is put in a long pile called a windrow and is aerated by a mechanical turner called an Aeromaster. Diligent monitoring of temperature, moisture and CO2 conditions in the windrows helps assure the time required for the material to biodegrade is minimized while it increases the quality of finished compost. Full Circle Compost plans to donate the finished compost to the Earth Day festivals. In this way, festival attendees are able to actually see the results of their participation in the recycling program.

South Lake Tahoe Earth Day
In 2004, the South Lake Tahoe Earth Day festival committee began taking steps to expand the event and agreed to move the event to the Heavenly Ski Resort in order to target a larger audience. In the past, standard recycling had been a part of the event but this year Earth Day committee members and NDEP were interested in going beyond that. Earth Day committee members agreed that zero waste was a worthy goal and voted to use funds from the Earth Day budget to supply participating food vendors with compostable servingware made from cornstarch, wheat resin, and sugarcane fibers.
Northern Nevada's Earth Day
Environmental Leadership (EL), a non-profit organization serving western Nevada, organizes and presents the annual Northern Nevada Earth Day in Reno. EL first started incorporating zero waste in to the event in 2003 and has made great strides in keeping the amount of waste associated with the event minimized. With support from NDEP, EL provided the food vendors with plates, cups, and other food serviceware made of biodegradable materials. Six waste stations were strategically placed around the event and "Green Team" volunteers, who had been trained on the proper separation of compostable and non-compostable wastes, monitored the waste stations. Volunteers also provided attendees with valuable information and education on the Zero Waste efforts and principals. On the day of the event, about 10,000 event attendees produced 467 lbs. of compostables, 350 lbs. of trash and nearly 1,000 lbs. of recyclables. Through NDEP support, compostable wastes were taken by Full Circle Compost of Minden, Nevada for composting. Truckee Tahoe Earth Day
The 2005 Truckee Tahoe Earth Day was held at the Village at Squaw Valley. The Tahoe Truckee Earth Day festival has been incorporating waste reduction practices in to the event since 2003. The Village at Squaw Valley worked with participating food vendors in the Village to ensure cooperation in zero waste efforts and to secure compostable servingware for each willing vendor. Three waste stations were positioned around the event and volunteers who had been trained on the proper separation of compostable and non-compostable wastes monitored trashcans. Volunteers also provided attendees with valuable information and education on Zero Waste efforts. On the day of the event, about 2,500 event attendees produced 142 lbs. of compostables, 60 lbs. of recyclables and 320 lbs. of trash Through NDEP support, compostable wastes were taken by Full Circle Compost of Minden, Nevada for composting.
SuccessesCombined efforts from all three events resulted in 735 lbs. of compost and 1,110 lbs. of recyclables being diverted from the landfill. The events created approximately 1,120 lbs. of trash for an impressive diversion rate of 62.2% across all three events. Furthermore, the Guess the Waste competition and giveaways provided at each waste station educated many event goers on the concept of zero waste and innovative technologies.
Waste Contest Results
The methods used to calculate the waste generated at the events included a combination of direct measurement and estimation. At Reno's Earth Day, nearly all wastes generated were collected and weighed by volunteers and NDEP staff. Links |
