Suranaree University of Technology has collected 372 kg/yr of electronic waste and sent them for disposal at a licensed waste management company authorized by the Department of Industrial Works once a year. Hazardous waste bins are provided for various buildings by type of wastes appropriately
2. Management of chemical waste from laboratories
The University gave consideration about management of the wastes from laboratories for the classes offered. The wastes are produced from the classes and research activities. A safety manual has been prepared for use in laboratories and with the chemicals. Part of the manual consists of the practice guidance for handling wastes in the laboratories so that it is carried out properly and safely. There is a system for separating wastes into 14 types. Labels are used to differentiate the type of waste. There are collection containers to store the wastes before they are sent to Licensed waste management company authorized by the Department of Industrial Works for further disposal or recycling process 3 times a year.
The Integrated Solid Waste Sorting Plant is a place for managing organic and inorganic wastes for Suranaree University of Technology. This plant uses Mechanical Biological Treatment (MBT) technology or composting method. The waste processing process for turning waste into organic compost and Refuse Derived Fuel (RDF) includes a waste segregation system using conveyor belt, grinder machine, MBT system and sieve machine for separating organic compost and plastics for the waste processing process. The by-product of these processes are organic compost and RDF.
On the World Environment Day, 5 June 2018, SUT declared the policy to reduce the use of plastics in all area under the “SUT Say No Plastic” campaign. There are 6 measures under implementation with the stores operating within SUT campus including,
Not providing single use plastic bags from convenient stores except for hot items.
Stop selling drinking water that uses cap seals.
Stop automatically giving single use spoons-forks-knives-straws and seasoning/sauces with purchase but have them available for the consumers to pick up if required.
Not using Styrofoam and single use clear plastic food containers (use only bagasse and paper based products).
Reduce the use of straws that is packaged in plastic and if necessary use straws with paper packaging instead.
Provide incentives including price reduction if consumers bring their own glass/ cups/mugs and food containers.
In this project used plastic bottles are melted and made into asphalt pavement sheets. This is to reduce the use of fresh asphalt by using plastics as substituting material. The mechanical properties of this material has been enhanced so that it has good load baring properties and can be applied to various types of work as follows.
“Sufficiency Medicine Bags” is the activity where used document envelops or office supply packaging bags are used to make bags for patients to medicine home. The activity also allows interested persons to help make, paint, color and decorate the bags. Donation stations are set up for paper and for bag folding activity as well as inviting interested persons to volunteer and help make the bags for the hospital to show their love and care for the patients who come to the hospital.
Suranaree University of Technology has set a target for reducing the amount of waste according to the “SUT Zero Waste” policy. This is in response to the development under the Green University strategy and the Ministerial Announcement of the Ministry of Higher Education, Science, Research and Innovation on the Policy to Support Sustainable Development according to the BCG principles. This is implemented by banning the use of plastics therefore the University held campaigns promoting the use of biodegradable cups for phase 1. A target was set to reduce the use of plastic cups and straws by 55% and promoted the use of biodegradable cups in 17 food stores and 9 drink and juice shops in the canteens. There were 26 coffee shops participating in the activity and it is estimated that this can decrease the use of plastic cups and plastic straws by 1 million pieces/year.
The University constructed and installed a water recycling system for reuse in the sanitation and garden sprinkler systems. The sprinklers are used for watering plants to reduce the problem of dependency on raw water when there is lack of water. The treated wastewater has been conditioned to have appropriate qualities for use and meets standard requirements for utility water for recycled water. Each year, SU is able to recycle water at the amount of 317,880 m3/yr. This reduced the use of tap water by 20%. The recycled water is used in the sanitary system throughout 73 buildings accounting for 60% of the buildings in the university. Recycled water is also transported for use for watering plants in 24 garden sprinkler locations throughout the university which is 70% of all the green areas that needs watering.
