Sustainability Report May 2013 To maintain an industry-leading approach to sustainable waste practices through reasonable and efficient management of our resources, early adoption of technology, and a clear focus on continuous improvement to current practices.

Welcome to a Cleaner World In 2012, we launched our first Sustainability Summary in which we invited our customers, our partners, and the communities we impact to review how Waste Industries had committed to providing a cleaner, quieter, and more sustainable world. The summary, available to anyone online at our corporate website, discussed how we at Waste Industries had approached sustainable business practices since our founding over 40 years ago. Today, one year after the launch of our first sustainability report, we are releasing our first sustainability report in which we will proudly share our ongoing efforts on an annual basis. This report will focus on all elements of our work over the past year, including both customerfocused sustainability, company-focused sustainability, charitable contributions to local communities, efforts at decreasing our environmental impact, and how we handle waste and recycling streams to provide the absolute highest level of service to our customers. While our company has always been completely committed to providing sustainable solutions since our founding, we are also never satisfied with saying OK, we have done enough. Every single day we restructure our priorities, refine our processes, and overhaul our fleets to maximize our effectiveness while simultaneously decreasing our environmental impact. It is with great pleasure that we invite you to review our sustainability report, where we hope to show you just how truly committed we are as more than just a company, but as individuals promising to build a more sustainable future. So to our friends, family, colleagues, and communities: Welcome to a cleaner world! Learn more at: www.wasteindustries.com/sustainability.aspx

Sustainable Billing One of the most wasteful methods of billing is the paper bill. Our residential customers are billed every quarter, meaning that four times a year from initial delivery of the bill to returning of payment, paper bill customers use two sheets of paper for the bill, an envelope to receive their bill, an envelope to send back their payment, and a check for payment. If you multiply that by our quarterly billing cycle, each customer is using 24 sheets of paper a year just to pay for their waste. We make every effort we can to ensure that paper is recycled, but many customers forget and that paper inevitably ends up in the trash along with other forms of solid waste. e-billing 2012 120,000 customers switched to e-billing, saving: 4 bills per quarter 1 check per bill 2 sheets of paper per bill 2 envelopes per bill 250 trees per year To prevent wasted paper and ensure we are maximizing our effectiveness in providing sustainable solutions to our customers, Waste Industries introduced our e-billing system. By 2012, we had 120,000 customers signed up for e-billing. Thanks to the contributions of our customers in switching to a fully electronic billing system, we effectively stopped the use of 720,000 pieces of aper in a single year. e-billing 2013 Added an additional 25,000 customers to e-billing. Saving 870,000 pieces of paper per year. In 2013 we have continued to grow our e-billing platform, proudly hosting 145,000 customers that are contributing to a paper reduction of 870,000 sheets of paper, every single year!
