U.S. looks to tackle plastic waste with new plastic-to-fuel technology
As plastic pollution continues to overwhelm landfills and pollute oceans across
the globe, the U.S. is looking towards new solutions to manage its plastic
waste in a more sustainable manner. One promising approach gaining momentum is
converting plastic trash into liquid fuel using advanced recycling
technologies.
The plastic waste problem
The United States generates over 32 million tons of plastic waste each year,
with only around 8.4% currently being recycled. Most of the non-recycled
plastic ends up in landfills or incinerated. However, plastic never fully
degrades and takes hundreds of years to break down in landfills. This plastic
waste is causing major environmental damage as it leaches into soils and
waterways or ends up polluting oceans. It is estimated that by 2050 there will
be more plastic by weight than fish in oceans if no action is taken.
Beyond just piling up in landfills, all this plastic waste also represents
wasted resources. Plastic is primarily made from oil and natural gas. When
plastic items are used just once and discarded, the embedded fossil fuels and
energy used to create the plastic are lost. This has major economic and energy
security implications for countries reliant on imported fossil fuels like the
U.S. Finding ways to reuse plastic waste as a source of energy could help
address both waste and energy challenges.
Plastic-to-fuel technology
Several companies are now developing and scaling up technologies that can
convert mixed plastic waste back into useful fuel. The most prominent
plastic-to-fuel process is called pyrolysis. In pyrolysis, plastic waste is
heated in the absence of oxygen to break the long carbon polymer chains in
plastic down into smaller liquid hydrocarbon molecules.
The hydrocarbons produced can then be further refined at an oil refinery into
various drop-in fuels like diesel, gasoline, and jet fuel. These fuels are
fully compatible with existing transportation fuel infrastructure and vehicles.
The pyrolysis process can handle mixed plastic waste streams of different resin
types together, including plastics previously not recyclable like flexible
films and multi-material composites.
Several large-scale commercial plastic-to-fuel facilities are in operation or
under development across Europe and Asia. In the U.S., companies like Agilyx,
Brightmark, and Dynamotive Energy Systems are working to deploy their own
proprietary plastic pyrolysis technologies at new commercial plants. These
plants aim to process tens of thousands of metric tons of plastic waste
annually that would otherwise go to a landfill or incinerator.
Government and private sector support
There is growing government and market support for scaling up plastic-to-fuel
technologies in the U.S. Several states have passed legislation or launched
initiatives to increase recycled content in transportation fuels. California
for example has set a target that at least 20% of diesel and jet fuel sold come
from waste or renewable sources by 2030.
At the federal level, the Biden administration has proposed increased funding
for advanced recycling R&D and circular economy projects through the
Department of Energy and EPA. Industry groups like the American Chemistry
Council are also pushing for policies and market incentives to boost plastic
recycling and support alternative plastic waste conversion technologies.
Major oil companies and waste management firms are also investing in plastic-to-fuel
startups. bp Ventures for instance invested in Brightmark's technology, seeing
it as aligned with their strategic focus on alternatives to virgin fossil fuel
production. As environmental regulations tighten and consumer brands face
mounting pressure to tackle packaging waste, plastic-to-fuel offers solutions
to directly address their material sourcing and recycling needs.
Challenges ahead
While plastic-to-fuel has gained momentum, challenges remain for scaling up
commercial deployment across America. Chief among these are securing a steady
supply of cheap post-consumer plastic waste feedstock, building public
acceptance for waste-to-fuel plants in local communities, and achieving cost
parity with established conventional fuel production.
Feedstock availability will depend on continued improvements in separate
collection and sorting infrastructure and policies. Strong waste diversion
targets and incentives are needed to encourage greater quantities of recycled
plastics. On the economics front, the process is capital intensive and subsidy
support may be required initially to offset higher costs compared to virgin
barrel production. Technology advancements aimed at improving yields and
throughput at plants can help drive down unit costs over time.
If these challenges are overcome, plastic-to-fuel offers a promising solution
to keep valuable carbon and energy locked in plastic waste circulating in the
economy rather than being lost to disposal. It could significantly boost
plastic recycling rates nationwide while providing a domestic source of
transport fuel advancing energy security and climate goals. With growing
momentum, the U.S. stands ready to tap plastic waste as an alternative fuel
resource of the future through investments in advanced recycling technologies.
