Local Food Waste Recycling Solutions

From Disposing Food Waste to Recycling it.
Helping Achieve SDGs by Reducing Waste Bulk and Waste Cost.

Food becomes waste when disposed of. It becomes a resource when recycled.
Local Food Waste Recycling Solutions is an initiative to create a food recycling loop by using food waste as compost to grow new farm produce. Food waste generated by food-related businesses is recycled into a resource at the compost stage, thereby cutting down the amount of waste disposal and at the same time significantly reducing waste cost. This process not only helps reduce food loss, which is a sustainable development goal (SDGs), but revitalizes local economies and helps us achieve a sustainable society.

Solution Overview

By utilizing food waste, Four Stars, recycling center and contracted farmers will be able to create a sustainable society.

The food waste generated from food-related businesses is fermented and decomposed into a primary fermentation product using Four Stars (a food waste fermentation/decomposition machine). The primary fermentation product is collected and then fermented again at the recycling center, making it into a high quality compost. That compost is supplied to contracted farmers for growing farm produce, which is then circulated, and thereby creating a sustainable society.

Do Not Dispose of Food Waste, Change it into Compost Material.

Food waste generated in food processing plants and related businesses can be used as compost material and therefore help reduce the amount of waste. If food waste is recycled with Four Stars (food waste fermentation/decomposition machine), the amount of waste requiring processing decreases.

Recycle Food Waste with Four Stars
(Food Waste Fermentation/Decomposition Machine).

FOUR STARS Food Waste Fermentation/Decomposition Machine
MDT-1000

Four Stars (food waste fermentation/decomposition machine) is at the heart of our solution. Food waste ferments and decomposes thanks to the power of microbes, creating the compost material or the primary fermentation product in about 24 hours. User operation is very simple, there are no unpleasant odors during fermentation, and CO2 can be significantly reduced when compared with the incineration process. There are 6 different sizes available to match the amount of food waste that is generated.

Make Compost From Food Waste

Food waste is recycled to make high quality compost. At the recycling center, moisture and temperature are maintained at optimum levels in order to create high quality compost.

  • Collect Primary Fermentation Product

    Collect Primary Fermentation Product

    Primary fermentation product decomposed by the food waste fermentation/decomposition machine is collected regularly.
  • Transport by truck
  • Composting in Recycling Center

    Composting in Recycling Center

    Our target is to promote maturing with secondary and tertiary fermentation using microbes and turn it into fully mature compost over a span of 3 months to 1 year.

Recycling and Composting Process

We use our composting expertise and IoT technology to create high quality compost that contracted farmers can rely on. Moisture control, temperature control and other tasks are carried out every day as part of composting at the recycling center. The control levels are carefully managed in the process until the primary fermentation product is matured. The pathogens and seeds remaining in the food waste are heated to a high temperature to kill them and ensure high quality recycling and composting that contracted farmers can rely on.

  • POINT01Moisture Control

    Moisture Control

    After the primary fermentation product is brought in and prepared following an established recipe, a moisture meter and/or other instruments are used to keep the moisture at an optimum level around 60%. If the moisture level is too high, a secondary material (such as rice husk) is added to adjust the level.

  • POINT02Temperature Control

    Temperature Control

    A special compost thermometer is used to check the fermentation temperature.
    Keeping the fermentation temperature between 60° and 70°C for at least a one month period helps the microbes with decomposing.

  • POINT03Cutback

    Cutback

    During the fermentation process, cutback work such as deep plowing, moisture control and stirring is carried out.
    Performing these work tasks helps create mature, high quality compost.

Recycling Centers Located Throughout Japan

Our Local Food Waste Recycling Solutions provides services for many food-related businesses and continues to expand throughout Japan. Our composting operations are currently running at our recycling centers that are set up all over the country in order to collect and recycle food waste for food-related businesses. Going forward, we have plans to expand our recycling center network further.

Rebuilding Social System for Sustainable Society

I believe that many companies have taken a strong interest in achieving SDGs and carbon neutrality through their businesses.

NTT BUSINESS SOLUTIONS has launched Local Food Waste Recycling Solutions to nurture and develop the future of agriculture and food in local communities. The goal of this concept is to help Japan solve issues at the community level caused by food loss, which is at the worst level in the world.

Integrating our solution means not only reducing costs but practicing food recycling in communities in order to create a sustainable society together with all stakeholders including food-related businesses and local farmers. As far as this concept of a loop, we can see the response definitely catching on and growing.

We must rebuild the existing social system to ensure a sustainable society and connect it with the next generation. We welcome and encourage everyone who supports this concept to partner with Local Food Waste Recycling Solutions.
