■ Challenges Before Installation: Reducing Environmental Impact and Suppressing Greenhouse Gases

At Aino University, the objective of the installation was to suppress the generation of greenhouse gases and reduce environmental impact by eliminating the disposal of food waste through incineration and landfilling.

⚠️ Challenges at the Time

  • Environmental Impact: Generation of greenhouse gases from incineration and landfilling.
  • Awareness Raising: Absence of a concrete mechanism to raise awareness of environmental conservation.
  • Hygiene Management: Risk of bacteria and virus outbreaks due to food waste being left for long periods.

■ The Decisive Factor: The Convenience of Decomposing Food Waste into Liquid and Automatically Discharging It

The greatest advantage of choosing GOMISER was its design, which decomposes food waste into a liquid and automatically discharges the generated liquid into the sewer. This eliminates the need to remove residue or pump out liquids, making it the decisive factor in enabling stable waste disposal with minimal burden.

For a Fail-Proof Selection

Food waste disposal at sites where consideration for the neighborhood and hygiene management are strictly demanded, such as residential areas and educational facilities, requires unique expertise. We have published selection criteria derived from AIC’s many years of experience.

■ Effects After Installation: A “Food Recycling Loop" Returning Harvested Vegetables to the Cafeteria

They achieved stable processing in a small space without worrying about odors, even within a residential area. Hydroponics is carried out on campus using the generated liquid fertilizer, and the harvested vegetables are returned to the student cafeteria. This cycle greatly contributes to raising awareness of environmental conservation among students and faculty members.

  • ✅ Food Recycling: Established a cycle of growing vegetables from liquid fertilizer and returning them to the cafeteria.
  • ✅ Awareness Raising: Educational effects allowing the entire campus to experience the SDGs firsthand.
  • ✅ Neighborhood Consideration: Suppresses bad odors and operates in a space-saving manner, even in residential areas.

■ AIC Specialist Comments

Reducing Environmental Impact and Contributing to SDGs

With growing environmental awareness, food waste disposers are attracting attention for their contribution to reducing environmental impact and achieving the SDGs.

Hygienic and Comfortable Work Environment

Introducing a food waste disposer also has the merit of improving the work environment and keeping it hygienic.

  • – Odor Reduction: Since the time food waste is stored at the facility is shortened, the generation of bad odors due to putrefaction can be suppressed.
  • – Pest/Animal Control: By reducing bad odors, the attraction of vermin and pests such as crows and stray cats can be suppressed.
  • – Reduction of Cleaning Effort: Hygienic disposal of food waste reduces the effort required for cleaning.
  • – Improvement of Unhygienic Conditions: It reduces the risk of bacteria and virus outbreaks caused by leaving food waste for long periods, keeping the site sanitary.

Q&A Regarding Installation


To eliminate food waste disposal through incineration and landfilling, thereby suppressing greenhouse gas emissions and reducing environmental impact. In addition, it aims to achieve an educational effect that embodies the SDGs through a system of utilizing the generated liquid fertilizer on campus.

It is the fact that it can decompose food waste into a liquid and automatically discharge it into the sewer. This eliminates the need for residue removal work, enabling stable operation while significantly reducing the burden on on-site staff.

We have received feedback from Aino University that “odors are not a concern even in a residential area." Because the GOMISER is designed for low odor and low noise, it can be installed with peace of mind even in urban areas where consideration for neighbors is essential.
