To help your compliance, please take our Restaurant Waste Stream Evaluation If you operate a restaurant in San Luis Obispo County, please take 5 minutes to complete the survey above. Your answers will be used by the IWMA to assess your restaurant's needs and help you gain compliance with state requirements. The information provided in the above survey will not be used to penalize you if your current practices are out of compliance. As a restaurant in the state of California, there are laws that regulate how you dispose of trash, recyclables and food waste at your business. Diverting material from the landfill is an important action we all can take to help keep our county clean and keep materials in circulation for future use. By recycling right, you demonstrate to employees and customers that your restaurant cares about sustainability, and you may find that you save money on your garbage bill. The IWMA can provide FREE bins, trainings and other resources to your restaurant to help you comply with these requirements.
