“No industrial facility wants to generate large amounts of hazardous waste. It’s not good for business and disposal is also a concern. The solution is to look at source reductions, as well as throughout the manufacturing process, to find out what generates large amounts of waste and the kinds of manufacturing processes we have that we can further streamline.”

Before adopting waste disposal practices in our plant management systems, I apply them in my home, where I make an effort to generate the least amount of household waste. For example, I always purchase products with an eye to reducing garbage. It’s also important to know what happens to your wastewater – where it ends up and how we can reduce water pollution. Recycled wastewater is ideal for watering plants. Food waste can be composted with organic materials such as leaves, twigs, and branches to make fertilizer. All of this ties in with supporting a circular economy. To be honest, I think that conducting effective integrated waste management practices at our plants is easier for me because of how I manage waste at home.

I’ve been an engineer for the last two decades, but I’m not only dealing with industrial waste generated from producing olefins and from other public utilities. I also take into account waste management measures for our office buildings.

Apart from implementing waste disposal practices, my cumulative professional experience has led me to play an integral role in implementing several initiatives related to the circular economy. This broadened my sense of purpose and understanding of reducing waste generated from our plants, and also promoting resource efficiency in a meaningful way.

No industrial facility wants to generate large amounts of hazardous waste. It’s not good for business and disposal is also a concern. The solution is to look at source reductions, as well as throughout the manufacturing process, to find out what generates large amounts of waste and the kinds of manufacturing processes we have, which we can further streamline.

It’s also important to adopt an integrated waste management system to keep waste to an absolute minimum. Practicing the 3Rs (Reduce, Reuse, and Recycle) provides the dual benefits of reducing the cost of transferring waste to a disposal facility and ensuring that waste can be recycled and reused. The result is less waste produced downstream.

The amount of waste that can be recycled by manufacturing facilities currently is around 30 to 40%. Successful cooperation by related sectors to handle waste at the source can further help solve several issues including indoor pollution in manufacturing plants and preventing hazardous accidents that may occur during waste collection and transport.

In addition, I’ve been part of a team that is successfully promoting the circular economy in conjunction with PTTGC’s Sustainable Development Goals (SDGs), which has resulted in PTTGC receiving several prestigious awards.

It’s worth pointing out that PTTGC has been responsive, as we received the Zero Waste to Landfill Achievement Award in 2015, in addition to obtaining Level 5, the highest level of the Green Industry Award. We were also commended for our highly-acclaimed “Green Idol” program, which has developed a green network and partnerships with our business partners to strengthen governance on environmental issues.

So we’re doing good work, but I’m determined to keep things going. For example, I plan on recycling 100% of the food waste from our canteens to produce compost and fermented water to use in our plants and share it with our employees and communities. In the next few years, all of the waste produced in our office buildings will be completely reused, as I intend to achieve zero waste to landfill, which means that all waste will either be reused, recycled, composted, or sent for energy recovery. This is an important goal for us internally, and I hope it encourages others to follow our lead.

We plan on sharing our experience with other organizations such as schools and other large businesses. For me, sharing this knowledge is vital, as it adds value for others and everyone will benefit.
