Reduction of Waste Generation and Recycling

Measuring In-Store Waste

Lawson continuously collects information on waste from stores for use as basic data in the promotion of waste reduction and recycling.

In fiscal 2017, average daily non-food waste per store amounted to 44.5 kg (data from 430 stores in Tokyo). Daily food waste averaged 11.4 kg, comprising 9.2 kg in unsold food and 2.2 kg in used cooking oil (data from the approximately 2,500 LAWSON stores that conduct food recycling).

Reducing Food Waste at Stores

Cutting Waste Generation and Promoting Recycling
In one day the average store generates unsold food, such as boxed meal-type foods that have exceeded their sell-by dates,* and cooking oil used in the preparation of fast foods, a total of 11.4 kg of food waste. Our efforts to reduce these types of food waste center on curbing the generation of waste and on recycling (the recycling of used cooking oil and converting surplus food into livestock feed or compost).
44.5% Food Recycling Ratio
Lawson and its Group companies strive to increase the food recycling ratio to effectively use surplus food and comply with Japan’s Food Recycling Law. Beginning from a baseline of 22.5% in fiscal 2007, we set the goals of improving our recycling ratio by at least 2 points each year. Thanks to these efforts, in fiscal 2017 we achieved a food recycling ratio of 44.5%, well in excess of the statutory target of 42.5% or above.

Initiative 1:
Curbing Waste Generation

Minimizing Unsold Products and Waste
In order to cut waste at the manufacturing stage, we have introduced the Production Process Management System, which entails carefully measuring ingredients used, product volume, and servings down to the gram.

We work to reduce waste by optimizing the merchandise assortment in stores. Sales data and purchasing data gathered through the multi-partner loyalty point program Ponta* is analyzed, taking into account such influences on the number of customers as day of the week, weather patterns, and regional events. Such efforts help us determine the optimal volume and assortment of merchandise for each store. This allows greater precision in ordering and helps reduce waste.

Initiative 2:
Recycling - Waste Oil

13,156 Lawson Group Stores Recycle Used Cooking Oil
Lawson began recycling waste oil in January 2006; as of March 31, 2018, 13,156 Group stores were participating. Industrial waste collection and transport contractors collect waste oil from stores, delivering it to recycling plants. There, it is processed into livestock feed additive, biodiesel fuel, and additive-free soap.

Lawson’s headquarters recommends companies that meet certain standards as business partners for stores, working through three management companies (in east Japan, west Japan, and Kyushu). Headquarters, the management companies and the headquarters-recommended partner companies closely collaborate to ensure and improve legal compliance, management standards, and quality of collection service.

Once a year, we invite partner companies from around Japan to participate in our Regular Waste Oil Recycling Meeting. Attendees share information and opinions and discuss challenges and solutions.

Initiative 3:
Recycling - Food

Expanding Food Recycling Coverage
Initiated in May 2006, waste food recycling by LAWSON stores had been adopted by 2,845 stores in the Lawson Group as of March 31, 2018. Boxed meals and other foods that have exceeded their sell-by dates are recycled into livestock feed and compost.

The Lawson Group is working to overcome challenges related to selecting food recycling plants and waste collection/transportation companies as well as the cost of recycling, aiming to expand the territory covered by its sustainable food recycling efforts.

In Toyama Prefecture and Nagaoka City, Niigata Prefecture, the recycling of unsold food from LAWSON stores includes fermentation to produce biogas*, which is then used to generate electricity.

*Biogas: Gas produced by fermenting such materials as food waste, sewage, or grain for use as fuel.

Example of Food Recycling 1
We began recycling unsold food into feed in Fukuoka City in October 2014. Unsold food is sent from the stores to a KANKYOU AGENCY CO LTD food recycling plant, where it is crushed, decompressed, dried, processed into feed and then shipped to pig farmers and feed manufacturers.
Example of Food Recycling 2
Lawson recycles unsold food from stores in five Toyama Prefecture municipalities, namely Toyama City, Imizu City, Kamiichi Town, Tateyama Town, and Funahashi Village. Unsold food from stores is transported to the recycling facilities of Toyama Green Food Recycle, Inc., where it is fermented to produce biogas and a liquid. The biogas is then used to generate electricity, which helps power the recycling facilities, while the fermented liquid is mixed with woodchipped, fermented tree prunings to create fertilizer.

Local Production for Local Consumption: Building a Food Recycling Loop
Selling Chiba Ecofeed Eggs

Six pack of Chiba ecofeed eggs

In June 2012, we began selling eggs produced by chickens raised partly on ecofeed-certified recycled animal feed at about 260 stores in Chiba and Ibaraki Prefectures.

Through this initiative, which we call the Food Recycling Loop, unsold food from stores is recycled as animal feed and fertilizer, which is used to produce agricultural products that are then sold in stores. Specifically, unsold food from LAWSON stores is recycled at factories into animal feed, which becomes part of the feed on which chickens are raised; the eggs that these chickens produce are then sold in LAWSON stores, forming a complete cycle, hence the name “Food Recycling Loop.”

This initiative utilizes unsold food from Kanto region (including Chiba prefecture) stores while serving fertilizer factories and chicken farms in Chiba Prefecture, and thus contributes to local production for local consumption.

Ecofeed Certification mark

“Ecofeed” Recycled Animal Feed

Ecofeed is animal feed produced using food waste (boxed meals, prepared food, sandwiches, etc.). Only feed that meets certain safety requirements and standards related to the usage ratio of food waste resources and feed manufacturing process control may be certified as Ecofeed.
