Evaluating Construction Waste Recycling Strategies in Myanmar: A Usability Assessment Based on Stakeholder Perspectives
This study evaluates thirteen construction waste recycling strategies in Myanmar through a stakeholder survey, identifying temporary bin organization, activity identification for recyclables, and policy enhancement as the most practical and effective approaches to improve waste management under local conditions.

Imagine the construction industry as a giant, chaotic kitchen where chefs are building skyscrapers instead of soufflés. Every time they chop, saw, or pour concrete, they create a massive pile of "kitchen scraps"—broken bricks, leftover wood, and dusty packaging. In the world of science, this is called Construction and Demolition Waste (CDW). For a long time, the standard recipe for dealing with these scraps has been simple: throw them all into a landfill, like tossing food waste into a giant, overflowing trash can. But just like a kitchen that never cleans up, this approach is messy, expensive, and bad for the planet's health.
The big idea this paper explores is "recycling," which is like teaching the kitchen staff to sort their scraps so the good stuff can be turned into new ingredients. However, not every kitchen has the same tools. Some have fancy, high-tech sorting robots, while others only have a few basic bins. The question isn't just "Can we recycle?" but "What is the easiest and cheapest way to start recycling right now, given the tools we actually have?" This study dives into that specific problem, looking at how to make recycling work in a place where the "kitchen" is still learning the ropes.
The Great Myanmar Construction Cleanup
In Myanmar, the construction scene is exploding. It's like a city that suddenly decided to build a million new homes and shiny new roads all at once. While this is exciting, it means a mountain of construction waste is piling up faster than anyone can clean it. Currently, most of this waste just gets dumped, which is bad for the air, the water, and everyone's health. The government has some rules saying, "Hey, let's be greener," but in the real world, the rules aren't being followed very well yet.
So, a team of independent researchers decided to play detective. They didn't just guess what would work; they went straight to the people actually holding the trowels and blueprints: 87 construction professionals, mostly project managers. They asked these experts to rate 13 different "cleaning strategies" based on three simple questions:
- Cost: Is it expensive (like buying a robot) or cheap (like buying a bucket)?
- Effectiveness: Does it actually clean up the mess?
- Ease: Is it hard to do, or can you just start tomorrow?
The researchers treated these strategies like items on a menu, scoring them to see which ones were the "best value meals" for Myanmar's current situation.
The Winners: Simple, Smart, and Doable
After crunching the numbers, the study found that the most practical solutions weren't the high-tech, expensive ones. Instead, the top three strategies were surprisingly simple, relying on organization rather than expensive machinery.
The Top Three Champions:
- S06: Organize temporary bins in each construction zone.
Think of this as putting a specific trash can for plastic, another for wood, and another for metal right next to where the work is happening. The experts said this is cheap, easy to set up, and very effective because it stops the mess from getting mixed up in the first place. - S07: Identify construction activities that produce recyclable materials.
This is like a chef knowing exactly which part of the vegetable they are cutting will be used for soup and which will be composted. By spotting beforehand which parts of the building process create waste that can be saved, workers can plan better and waste less. - S12: Enhance company waste-related policies.
This is the "boss's rulebook." If a company officially says, "We are going to recycle," and writes it down in their plans, the workers are much more likely to actually do it. It's about making recycling a habit, not just a suggestion.
What Didn't Make the Cut?
The study also looked at some flashier ideas, like using fancy software databases to track every piece of trash (S08) or trying to get expensive international green certifications (S04). The experts rated these much lower. Why? Because in the current Myanmar context, they are seen as too expensive or too difficult to pull off right now. The paper suggests that while these might be good for the future, they aren't the best place to start today.
Interestingly, the researchers found that while most people agreed on the top three, there were some small disagreements about the cost of certain strategies between different groups (like contractors vs. clients). However, the overall message was clear: Management and planning beat expensive technology.
The Bottom Line
This paper suggests that you don't need a million dollars or a supercomputer to start recycling construction waste in Myanmar. You just need to get organized. By placing bins in the right spots, knowing what waste you're creating before you create it, and making it a company rule, construction sites can become much cleaner and more efficient.
The researchers are careful to say that these findings are based on what professionals think will work, and more study is needed to see how it plays out in real life across different parts of the country. But for now, the message is hopeful: the best way to fix the mess isn't to wait for a miracle machine; it's to start with a few simple bins and a clear plan.
