a group of The researchers produced the biopolyol by liquefying the plant materials Such as the pulp of beets, tomatoes, peppers, lavender, oregano, peas, and red bean hulls in Eskisehir Technical University laboratories are advanced for Patented.
within range of Zero Waste Project, prof group of research Students from Eskişehir Technical University (ESTU) obtain polyols,”one of the basic input of Polyurethane and polyurethane compounds used as insulation materialsby liquefying plant waste which is one of the main Objectives of industry stakeholders,” said Murat Erdem, prof professor from the University’s Department of Chemistry.
has been launched in 2018 with a team made up of Erdem, retired lecturer professor Hayrettin Turk, Associate Bilge Erdem, research Assistant Emre Akdogan, graduate students Ahmet Erdem and Duygu Kyrat, and chemist Furkan Çolakoğlu.
the research team Rigid polyurethane foam is produced from bio-polyols obtained by liquefaction plant materials Such as the pulp of sugar beets, tomatoes, lavender, thyme, pulp of peppers, peas, and red beans with a special method.
Academics also add Some polyol chemicals to obtain polyurethane with some extra performance properties like improved sound And the heat Insulation, flame retardant and antimicrobial effect.
experts who Production of polyols, which are defined as organic compounds containing Multiple hydroxyl groups have been applied and are mostly imported, from plant waste for Patent to the Turkish Patent and Trademark Institute, in particular for product used heat And the sound insulation product in areas like home Hardware, defense, space, aviation and construction.
Erdem explained that the polymer materials They are mostly produced from petroleum-based, non-renewable resources.
stating that the environment problems caused Through oil consumption and increased production costs due to international price Oil policies, dependence of polymers on Non-renewable resources are getting bigger problem.
“the use of biological resources in Polymer production has become one of the most important research Threads of our time. When concepts such as resource-based renewable energy, sustainability, green chemistry and like It is polyurethane that we are working on onshe first Polymers that come to mind. Basically, it is obtained through interaction of Diisocyanates and polyols. Producer and consumer of polyurethane in the global marketwe are currently one of polymers with the highest production and consumption. One of The most important input for polyurethane polyol. Reduce production and consumption of Petroleum-derived polyols and their replacements with Biopolyol is one of the main Objectives of Researchers, institutions and companies.
Erdem mentioned that he was working with Postgraduate and Ph.D. students on output of Biopolyol especially on Rigid polyurethane foam, which is widely used in thermal insulation.
stating that they were working for Four years to obtain biopolyols from biomass with Thermal liquefaction method with acid solution, Erdem said: “We liquefy the compost material Used as a mushroom seed host in output of Sugar beet pulp, tomato, pepper, lavender and thyme pulp, peas and beans, olive pomace and oyster mushroom production. grape waste material Released during production of hardaliye, the local brew of Kirklareli regionin between materials We can liquefy it and get biopolyol from it.”
Emphasizing that they increase their economic value by making bio-polyols from the biomass that appears as waste: “We can reach 95% efficiency depending on on Type of Biomass in monetization operations. We can get bio-polyol in About two hours, including separation and purification processes. in the end of liquefaction process, waste material Production depends on its efficiency. We value this material by us call Secondary waste is within range of the zero The concept of waste within these processes. In other words, we are also add waste value of waste.”
The Zero Waste project was led by Türkiye fight against Climate change. The initiative is primarily aimed at bringing the country in Line with sustainable development principles, prevent uncontrolled waste and leave “cleanliness,” developedcountry to future generations.
Project Zero Waste is new Noun for Recycling in Turkey since 2017. Gaining momentum with diversity of Thanks to recycling technologies first Mrs. Emine Erdogan who The national campaign To spread the idea of Minimize litter to public. the project It aims to increase recycling in Turkey rate to 35% by 2023, while creating employment for about 100,000 people in recycling industry and saving 2.3 billion dollars (20 billion TL) annually.
