SUSTAINABILITY Initiatives for Global Environmental Conservation

Waste Reduction

The Lawson Group generates food waste as well as other waste, including plastic bottles and cardboard. We also generate industrial waste such as construction materials during the construction and renovation of our stores. In order to reduce our environmental impact and prevent pollution, we at the Lawson Group are working to reduce and properly dispose of waste in accordance with our Environmental Policy.
In particular, we consider the reduction of food loss to be an extremely important issue, and are working to reduce food loss by controlling the amount of waste we generate 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 2020, average daily non-food waste per store amounted to 32.0 kg (data from 450 stores in Tokyo). Daily food waste averaged 7.9 kg, comprising 5.5 kg in unsold food and 2.4 kg in used cooking oil (data from the approximately 2,700 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 7.9 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).
58.4% 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 2020 we achieved a food recycling ratio of 58.4%, well in excess of the statutory target of 48.5% 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.
In addition, as part of our efforts to reduce the number of unsold products in our stores, we encourage discount sales by using discount keys on POS cash registers and discount stickers registered as consumables. We are offering discounts on items such as ready-made meal products with short consumption periods, fast food prepared on site, and products from Machikado Chubo in-store kitchens.

Initiative 2:
Recycling - Waste Oil

14,112 Lawson Group Stores Recycle Used Cooking Oil
Lawson began recycling waste oil in January 2006; as of March 31, 2021, 14,112 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 2,634 stores in the Lawson Group as of March 31, 2021. 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 six Toyama Prefecture municipalities, namely Toyama City, Imizu City, Kamiichi Town, Tateyama Town, and Funahashi Village, and Namerikawa City. 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.
