Planning Eco-Friendly Events

From weddings to corporate conferences, events generate significant waste. A waste audit estimates how much trash can be diverted from landfills through recycling and composting. Knowing these numbers helps organizers design better waste stations, order the right bins, and educate attendees. This calculator offers a simple way to plan sustainable gatherings.

Waste Diversion Formula

The basic equation multiplies attendees by average waste per person . Applying a diversion percentage yields diverted material :

The remaining waste is . You can adjust these variables to see how improved diversion rates reduce landfill impact.

Typical Diversion Rates

Event Type	Average Diversion
Small Meeting	40%
Music Festival	60%
Zero-Waste Fair	80%

These estimates depend on available recycling infrastructure and attendee participation. Clear signage and volunteer sorting stations go a long way toward boosting diversion.

Why Track Waste?

Audit results help you identify the largest waste streams—often food scraps, packaging, and disposable decor. With data in hand, you can work with caterers to reduce single-use items, encourage reusable cups, and partner with composting services. Tracking progress over time also demonstrates commitment to sustainability, which can attract sponsors and environmentally conscious attendees.

Example Scenario

Say you’re hosting a 200-person outdoor conference where each guest generates about 1 kg of waste. If you divert 60%, the calculator shows 120 kg diverted and 80 kg sent to landfill. Printing this information on signage encourages guests to sort items carefully, helping you achieve or even surpass your target.

Conclusion

Small changes add up. By auditing waste in advance, you can set realistic diversion goals and keep your event as green as possible. Use this tool to experiment with attendance numbers and diversion rates, then coordinate recycling and composting efforts so less trash ends up in the bin.
