But — and yes, there is a “but” — here are my thoughts and suggestions
* Patent and market – If the machine works as promised, the government should support CLSU to patent it, then help market it to LGUs, barangays, cooperatives and the private sector. Without the “business side”, it will stay as a prototype.
* Deploy to cooperatives – Instead of giving one machine to one barangay, the model should be coop-owned (think: multiple barangays share it), ensuring high utilization, cost-sharing, and maintenance economies of scale.
* Link to MRF upgrades – The machine is a tool—but it must sit inside a functioning system. Many MRFs are under-resourced. Integration means training operators, ensuring power supply, maintenance support and a market for sorted plastics.
* Cost-benefit evaluation – We need hard numbers. How many kilos of plastic can it sort per hour? What is the cost of the machine vs the value of the plastics reclaimed? How many jobs are supported? If these numbers are favorable, budget allocations will follow.
* Beyond PET bottles – The current machine sorts PET bottles into categories. But much of our pollution is multilayer sachets (which alone account for perhaps 52 % of the residual plastic waste stream), and difficult-to-recycle plastics. Future versions might expand to other resin types or complex formats.
* Incentivize collection – A machine is only as good as the feed-stock. Barangays must improve waste segregation at source so that the sorting machine isn’t processing highly mixed or contaminated waste (which reduces value).
* Monitor impact – Collect data on contamination rates before and after machine deployment, volumes processed, plastics sent to recycling vs landfill/leakage. Show public impact.
My questions to policymakers
* Why hasn’t the government already scaled such technology? Is it funding, awareness, logistics or incentive structure?
* Can the Department of Environment and Natural Resources (DENR) or the Solid Waste Management Commission adopt this in their circular economy roadmaps?
* Could the machine become part of LGU waste-management grants so that barangays can access it?
* Will there be mechanisms to ensure local manufacturing of spare parts to avoid “dead machines” languishing in the field?
Final word
In a country drowning (literally) in plastics, we need more than fines, bans, slogans. We need solutions. The sorting machine from CLSU is not a silver bullet—but it is a practical, locally-rooted step forward. If we use it well—with policy support, finance, and operations—it could make a measurable dent in our plastic waste problem.
Here is the crux: innovation must meet deployment. A brilliant machine unused in a warehouse helps no one. But one humming away in a barangay, sorting plastics which were once littering our streams, becomes a symbol of change.
Let’s not let this machine sit idle. Let’s not let our plastics keep overwhelming our rivers and oceans. Let’s mobilize, scale up, refine and deploy. Because if we don’t act now, we’ll be the ones sorted out by our plastic legacy./PN
