COULD WASTE PLASTIC BE PROCESSED BACK INTO DIESEL AND GASOLINE?

COULD WASTE PLASTIC BE PROCESSED BACK INTO DIESEL AND GASOLINE?

The short answer is yes. In fact, the technology already exists and has been tested for years. The process is called pyrolysis, and it essentially “unmakes” plastic by heating it to extremely high temperatures—usually between 300°C and 900°C—without oxygen. Instead of burning, the plastic breaks down into smaller hydrocarbon molecules that can become fuel oils such as diesel or gasoline.

In simple terms, plastic originally came from petroleum. Pyrolysis simply reverses the process by turning the plastic back into oil-based fuels.

When plastic waste undergoes pyrolysis, three products normally emerge. The first is pyrolysis oil, which can be refined into diesel, gasoline, or even used as feedstock for making new plastics. The second is synthetic gas, which can power the plant itself. The third is char, a carbon residue that can be used as industrial fuel or additive.

Perhaps this technology has been around for decades but received little attention because oil was abundant and relatively cheap. But the global situation has changed. Wars, supply disruptions, and geopolitical tensions have made imported fuel more expensive and uncertain.

For a country like the Philippines that relies heavily on imported petroleum, this should raise a very important question: Are we overlooking a resource that is literally piling up in our streets and landfills?

Consider this: the Philippines is projected to generate around 23.6 million tons of solid waste annually, much of it plastic.

Instead of allowing these plastics to clog waterways or end up in the ocean, why not convert a portion of them into fuel?

In fact, there have already been local experiments. A Filipino inventor operating in Payatas was able to process about two metric tons of plastic waste per day and produce roughly 1,600 liters of fuel through pyrolysis technology.

That is not a laboratory curiosity. That is real fuel.

Of course, let us not pretend that this is a perfect solution.

The technology has its pros and cons.

On the positive side, it diverts non-recyclable plastics—such as sachets, films, and laminated packaging—from landfills. It can also produce fuel with lower sulfur content compared with conventional diesel.

However, there are challenges. The process requires high temperatures, meaning energy input is needed. Contaminated plastics, especially those containing PVC, can produce corrosive or toxic gases. And at present, producing fuel from plastic can sometimes cost more than drilling crude oil.

Environmentalists also point out that burning plastic-derived fuel still releases carbon dioxide into the atmosphere. Some argue that turning plastic back into new plastic would be a better long-term solution.

Still, as a bridge technology, plastic-to-fuel has enormous potential.

Imagine if the Philippines could replace even 5% to 10% of imported fuel using waste plastic. That may not eliminate our dependence on imported oil, but it could significantly reduce it.

More importantly, it would address two problems at once: garbage and energy security.

So the question is no longer whether the technology works.

The technology is already here.

The raw materials—millions of tons of plastic waste—are also here.

The real question is: Who will take the lead?

Should it be the Department of Environment and Natural Resources, the Department of Energy, the Department of Science and Technology, or the Department of Trade and Industry?

Perhaps all of them should work together.

And perhaps someone should bring this idea to the attention of Ferdinand Marcos Jr..

The oil crisis is already here.
The plastic waste crisis is already here.

The technology to address both is already here too.

So the real question is: What are we waiting for?
