Puey Ungphakorn Centenary Hall is a learning center on building design that reduces greenhouse gas emission and adaptation to climate change. The design of Puey Ungphakorn Centenary Hall includes simulating a catchment area in a form of rice terraces and growing plants on the building to optimize cultivation area and serve as learning area for the public.

Converting carbons to edible

Vegetables has been planted in the rooftop urban farm of Puey Ungphakorn Centenary Hall with the concept of “converting carbons to edibles”, which is to grow vegetables that absorb carbon dioxide during their growth. Fertilizers used in the park are made of composts, such as twigs and leaves from tree trimming in the University, which have been digested. This reduces the use of chemical fertilizers and carbon emissions from fertilizer production process. The compost fertilizers are the main source of minerals for trees and plants in the University which also help reduce the amount of organic waste. In 2009 – 2011, the University can produce up to 120 tons of compost fertilizers.

In addition, food waste on campus is turned into liquid biological fertilizer for use within the University in order to reduce the amount of food waste from each building and to build awareness on waste sorting. Since the project started in 2020, 520 cubic meters of biological fertilizer has been produced.

Biochar has also been produced from twigs with diameters of more than 5 inches with a production capacity of 50 kilograms per month.
