Thai Researchers Transform Agricultural Waste into Valuable Ceramic Gemstones

Published

Suranari University of Technology Innovates with Agricultural Byproducts

Researchers at Suranari University of Technology (SUT) have made a groundbreaking advancement by creating ceramic gemstones from agricultural waste, significantly increasing the value of these materials. The innovative project has resulted in gemstones priced 6,000 times higher than the original agricultural waste used in their production.

Inspiration Behind the Research

Utilizing Thailand’s Agricultural Resources

The research team, consisting of senior students from the Institute of Engineering’s School of Ceramic Engineering—Parnpailin Jaichuei, Chatcha Chuma, and Saowalak Boonpakdi—was motivated by Thailand’s status as a major agricultural producer. With rice and sugarcane being key crops, the country generates substantial agricultural waste each year, including straw, husks, and bagasse.

Addressing Environmental Concerns

Ms. Saowalak highlighted that much of this waste is often underutilized and either turned into fertilizer or burned, contributing to air pollution. This environmental concern prompted the team to explore how these byproducts could be repurposed effectively.

The Process of Creating Ceramic Gemstones

Analyzing Agricultural Waste

The research began with an analysis of the properties of agricultural waste, revealing high silica content in materials like rice husks. Since silica is a primary component in natural gemstones, the team decided to develop a method for transforming these wastes into valuable ceramic gemstones.

Innovative Production Techniques

The production process involves several steps:

  • Calcination: The agricultural waste is subjected to calcination at temperatures of 300°C, 500°C, and 700°C, converting it into high-quality ash.
  • Mixing and Liquefaction: This ash is then mixed with additives using ceramic engineering techniques and liquefied at 1,300°C to form molten glass.
  • Cooling and Solidification: After cooling, the material is reheated in a ceramic oven at 550°C for enhanced durability before slowly cooling again for stability.

Characteristics and Applications of the Gemstones

Durability and Aesthetic Appeal

The resulting ceramic gemstones not only mirror the colors of their original materials but also possess durability comparable to natural gemstones. Their size and strength make them suitable for various industrial applications.

Economic Benefits

By transforming low-cost agricultural waste (valued at around four baht per kilogram) into high-value gemstones (totaling approximately 24,000 baht for 20 pieces), this innovation adds significant economic value to what was previously considered waste.

A Sustainable Future with Innovative Solutions

The creation of ceramic gemstones from agricultural waste by SUT researchers exemplifies how innovation can lead to sustainable practices while addressing environmental concerns. This project not only showcases Thailand’s potential for utilizing its agricultural resources but also highlights the importance of research in creating valuable solutions that benefit both the economy and the environment. As industries continue to seek sustainable alternatives, initiatives like this pave the way for a greener future.

Job Seekers Deceived by Fraudulent Brokers

Approximately 250 individuals were left stranded at Suvarnabhumi Airport on Saturday after being promised employment opportunities in Australia and Israel by job brokers. The disappointed job seekers reported that they collectively paid around 12 million baht in broker fees.

Formal Complaints Filed with Authorities

On Monday, fifty of the affected individuals took action by filing formal complaints with the Central Investigation Bureau (CIB). One victim, Narongchai, 42, disclosed that they had paid between 60,000 to 120,000 baht each to a woman known as “Ms. Aoy” to secure various job placements in Australia.

Promises of Work in Israel

Other victims, who also filed complaints with the airport police on Saturday, claimed they were promised jobs in Israel. Ms. Aoy appeared at the airport and stated that she had transferred the victims’ funds to another individual named “Ms. Fa,” who allegedly worked at a foreign embassy and claimed to facilitate overseas job placements for Thais.

Ms. Aoy’s Claims and Victims’ Frustration

Ms. Aoy assured the victims that she would present the visas she arranged for them to the Crime Suppression Division on Monday to prove her innocence. However, as of Monday morning, the victims were unable to contact her, exacerbating their frustration and concern.

Government Response and Warnings

Government deputy spokesman Karom Ponpornklang announced that the Department of Employment and the Ministry of Labour were assisting victims in filing their complaints with the CIB’s Anti-Trafficking in Persons Division. The Ministry has also instructed the airport labor checkpoint to closely monitor job brokers for illegal activities.Karom emphasized that Thai citizens seeking work abroad must do so legally and should thoroughly vet brokers before handing over any money. He reiterated that overseas job agencies must be approved by the Department of Labour to ensure legitimacy.

A Call for Vigilance Among Job Seekers

This incident serves as a stark reminder for job seekers about the importance of verifying the legitimacy of job offers and brokers. As authorities investigate this scam, it highlights the need for greater awareness and regulation to protect individuals from fraudulent schemes targeting those seeking better employment opportunities abroad.
