This case study outlines the waste management optimization efforts undertaken by Rubicon Technologies for two major retail chains in the United States. The first chain, a discount variety store with over 16,000 locations, initially faced a waste expense of $20 million, which was significantly reduced to $11 million after implementing Rubicon's reverse logistics solution for cardboard. The program involved the removal of 11,000 frontload containers and optimized service frequency based on sales and foot traffic, resulting in a net benefit of $34 million. The second chain, a global big-box retailer with thousands of locations, experienced a reduction in waste expenses from $180 million to $95 million through similar strategies. This included the hiring of independent waste companies and the use of data analytics to schedule services only when necessary, leading to a dramatic reduction in costs and resource waste. Both cases illustrate the effectiveness of Rubicon's approach to waste management.
