Circular Economy

Circular economy is a replacement of the previous linear economy which resources are used for production. Products later become waste (Take Make Dispose). The circular economy changes the concept to be production, consumption, and remanufacturing (Make Use Return). This is for sustainable growth based on environmentally-friendly quality of life which is consistent to Sustainable Development Goals (SDGs) of the United Nations in Target 12: Responsible Consumption and Production. This goal aims to change production, consumption, and effective natural resources consumption, disposition of waste garbage, recycle support with solid waste reduction, and Target 13: Climate Action which help in greenhouse gas emissions causing global warming.

Mahidol University focuses on circular economy which helps with waste reduction. Waste management of Mahidol University starts from consumption, activities, learning by developing knowledge to continuously solve the problems stage-by-stage. Firstly, “Adaptation for Change” in the university starting with waste management in the university brings waste to recycle for reuse purpose. Recyclable waste can be brought to Waste Recycling Bank. Leaf fragments around the university can be made to fertilizer, and organic waste can be made to bio-fermented water. Next, sharing “Knowledge” to society is to pass on knowledge to interested people, to build connection in waste management from household level to provincial level. After that would be upcycling which brings recycled waste to be processed creating new products.

Moreover, the “Sufficiency Model” project under the concept of sufficiency economy philosophy is adapted with university concept. It is displayed through an exhibition located at Environment Conservation Building, Mahidol University, Salaya Campus.

“Adaptation” for “Change” in the university
Waste Recycling Bank

Waste Recycling Bank established in 2009. This campaign is to encourage divisions, students, and staff to change their mindset of waste and behavioral change to start sorting and bringing waste to the Waste Recycling Bank. The Waste Recycling Bank is similar to commercial bank where you can deposit and withdraw cash. The difference is we deposit recyclable waste and withdraw them in cash. There is a software to collect member’s data which is reliable and verifiable.

Everyone can be a member of Waste Recycling Bank. The process of application is easy using only an application form with an identification card. After the date recorded on the system, a bank book will be given. Members can sell their sorted waste and withdraw in cash or deposit with the bank. The purchase price of recyclable waste is clearly announced and adjusted every three months based on the market price.

Currently, There are more than 2,500 members who have applied for the project and 5,000 general members who have a total amount of recycled waste of more than 2,700 tons, representing a total purchase of recycled waste of more than 11 million baht, with a profit of 10% from sales. Recycled waste will be deposited into the environmental conservation fund. Mahidol University

The project has been running over 10 years. This is to bring recyclable waste of more than 2,700 tons for reuse purpose which separates recyclable waste from others. This also helps governmental waste management.

Production of fertilizer from plant waste with aeration pile system

The production of humus (organic soil conditioner) started in 2008, utilizing branches and leaves from the university's departments and common areas to reduce burning, lower environmental maintenance costs, and promote reuse.

The humus production process begins with shredding branches and leaves, then piling them up and mixing them with cow manure. The composting process takes 30-45 days, after which the mixture is sun-dried and crushed into smaller pieces. The compost is left for about 3 days to allow microorganisms to settle before being used or packaged for sale. Since operations began in 2008, more than 320 tons of compost have been produced, valued at over 2.5 million baht, and the production site has become a learning center for various organizations visiting to study the process.

Currently, there are two types of humus available for sale:

1. Powdered Form

1. Unpackaged: 7 baht per kilogram
2. Packaged: 8 baht per kilogram

2.Granulated Form

1. Unpackaged: 30 baht per kilogram
2. Packaged: 30 baht per kilogram

Bio-fermentation Production

The Environmental Conservation Building became the first location at Mahidol University to produce "bio-fermented water" in 2009, by combining effective microorganisms (EM) with molasses for three days. The benefits of bio-fermentation water can be used in wastewater treatment, eliminate bad odors from garbage, and is used to restore abandoned land by using microorganisms to accelerate the decomposition of organic matter in the soil to make the soil in good condition. It is offer at the rate of 5 baht per liter, with the earnings benefiting Mahidol University’s environmental conservation activity fund Mahidol University.

Sharing “Knowledge” to Society

The university has the concept of using knowledge and experience from various operations to give the community services. In order to better people's lives and the environment.

Eco Town Project

In 2016, Mahidol University started the project on Eco Town to serve schools with the knowledge on recycled waste bank management and promote the establishment of a recycling waste bank project. This project aims to transfer waste separation knowledge to students, teachers, and parents by providing not only supporting materials, equipment, knowledge, and the programs but also advice and guidance on the management of the recycled waste bank to teachers and students who manage the school's recycled waste bank project as well as demonstrations and guidance on project implementation. As a result, collaboration is essential for achieving practical outcomes and ensuring operational sustainability. We have launched a pilot project for model schools at the early education level with the purpose of instilling waste separation and saving practices.

Knowledge enhancement and understanding of waste reduction for students, teachers, and parents to participate in reducing the amount of waste and generating income from waste to improve people's lives and the environment for their communities and schools, as well as help to create a low-carbon society. The Eco Town project is in line with government policy regarding solid waste and hazardous waste management. This project will help school have a good environment suitable for teaching and learning as well as a model school between educational institutions and community. Schools participated in the project are as follows:
