Retail Insight creates a new model to help Walmart reduce food waste

The retail giant now enjoys increased time-to-value, while reducing retail waste year-on-year.

Waste from unsold items is a long-standing problem facing grocery retailers. The United Nations estimates that around one-third of all food produced is thrown away, the cost of which isvalued at around $1 trillion per year globally. Waste reduction helps retailers tackle this cost while also creating ethical and commercial advantages for retailers.

Environmental and ethical concerns

In addition to the environmental and ethical concerns, for retailers there is also a financial concern, with waste costing on average between 3% and 5% of sales, rising above 10% in some cases.

Addressing the challenge of markdown

Retail Insight, the retail data experts, reduce customers’ overall exposure to waste through addressing the challenge of markdown.

For example, Retail Insight has been working with Walmart since April 2017 on multiple fresh food departments across its US store network. The time-to-value has been very fast, with Walmart experiencing an immediate year-on-year reduction in waste as soon as the project began.

Seamless integration

The RI system integrates so seamlessly with Walmart that there are no additional steps, stages or processes for employees to follow.

“We’ve developed a new model for waste and markdown activity that is dynamic and flexible. Markdown prices are automatically flexed to give the customer the best value price for the markdown product, with variable markdown rates depending on all the key factors and influences affecting each product and each store, including seasonality, demand and shopper behavior.

In addition, the model minimizes the volume of unsold stock and maximizes revenue from sold markdown items.”
