Hawaii's recyclables, including plastic, are sent to other countries, such as those in Asia, or to the mainland US. However, the state's recycling capabilities are limited, and it does not have a traditional recycling facility. This means recyclables must travel thousands of miles, and there is little incentive for cities or companies to collect recyclables if there is no buyer. As a result, Hawaii County recently stopped collecting plastic and paper. The high costs of operating on an island, including real estate prices, storage space, and transportation, make recycling a challenge. Some advocate for reducing and reusing as more effective ways to manage waste, while others experiment with plastic-to-fuel technologies.

What You'll Learn
Plastic waste is sent overseas for recycling
Hawaii does not have a recycling facility, so plastic waste must be sent overseas to be recycled. The state's plastic waste is sent to the mainland United States, as well as various Asian countries, including Taiwan, Malaysia, Thailand, and Vietnam. The lack of a local recycling facility means that recyclables must travel thousands of miles, resulting in higher transportation costs and a larger carbon footprint.
Hawaii County has stated that its paper, cardboard, and scrap metal are shipped to Asian countries, while its plastic and aluminum are sent to the mainland. Kauai County sells its mixed paper and cardboard to Taiwan and its plastic and aluminum to companies in California. The high cost of living and real estate prices in Hawaii also contribute to the challenge of recycling, as recycling companies must regularly clear out warehouse space, making it difficult to stockpile large amounts of low-value plastics.
There are efforts to address the issue of plastic waste in Hawaii. The state has a plastic bag ban in place, and over 200 restaurants have pledged to be "Ocean Friendly Restaurants" by reducing their use of single-use plastics. Additionally, some companies are experimenting with plastic-to-fuel technology, which involves melting down plastic into fuel for ships and planes. However, the low price of oil makes it challenging for these companies to compete.
Despite these initiatives, Hawaii continues to face challenges in managing its plastic waste sustainably and economically. The state's unique geographical challenges, high operational costs, and market dynamics influence the feasibility of recycling initiatives.

Plastic-to-fuel technology
Hawaii, like many other places, does not produce enough plastic waste to make a traditional plastic recycling facility economically viable. As a result, the state has had to ship its recyclables to large recycling plants on the mainland, thousands of miles away. However, this model has been criticised as a waste of financial resources.
One alternative to traditional recycling methods is plastic-to-fuel technology, which has been around for years. This technology uses pyrolysis to break down plastics into hydrocarbon molecules through thermal decomposition. The resulting hydrocarbon compounds can then be refined to obtain usable fuels such as gasoline, diesel, and kerosene.
There are several companies experimenting with plastic-to-fuel technology, including New Hope Energy, which can produce 4,500 barrels of fuel per day at peak capacity. Another example is Plastic2Oil®, a clean energy company that recycles waste plastic into liquid fuels.
The benefits of plastic-to-fuel technology include the fact that fuels produced from plastic waste can be tailored to meet specific needs, such as fuel for industrial, aeroplane, ship, locomotive, or diesel engines, and boilers. The process also reduces the amount of plastic waste that would otherwise end up in landfills or the ocean.
However, there are also challenges and concerns associated with this technology. One concern is that plastic waste-to-fuel will undermine the economy of other waste-to-fuel processes. There is also the argument that using waste-to-fuel programmes does not resolve the issue of overreliance on plastics but instead increases their usefulness for the same amount of environmental impact.

Plastic straws are not banned in Hawaii
Plastic straws are not banned across the entirety of Hawaii. However, the state has implemented various measures to reduce plastic waste and encourage recycling. Cities in Hawaii have adopted Food Ware and Plastic Bags Bans to mitigate the impact of plastic on the environment. The use of disposable single-use plastic food ware, including plastic straws, is prohibited in Honolulu, which has implemented waste management policies to protect the environment, reduce climate change, and safeguard the health of humans, animals, and marine life. The county of Maui has also banned plastic straws and stirrers.
Businesses in Honolulu and Maui that do not comply with the law face fines of $100 to $1,000 per day of violation. All businesses, including groceries, restaurants, farmer's markets, and retailers, must comply with the laws banning single-use plastics in these areas. Additionally, some hotels in Hawaii have voluntarily stopped providing plastic straws to reduce pollution.
While Hawaii faces challenges due to the high cost of transporting recyclables to large off-island plants, there are ongoing efforts to address plastic waste. The Hawaii Legislature passed Act 254 in December 2020, officially forming the Plastic Source Reduction Working Group to promote the reuse, reduction, recycling, and recovery of plastic waste. The state is also exploring innovative solutions, such as plastic-to-fuel technology, to manage plastic waste more sustainably.

Plastic bag ban in Hawaii
Honolulu's Bill 40, signed into law in April 2012, is a plastic bag ban that prohibits businesses from providing single-use checkout plastic bags and non-recyclable paper bags to customers. The bill was put into effect on July 1, 2015, and has since evolved to include thicker, "reusable" plastic bags in the ban and establish a minimum 15-cent charge for reusable, compostable plastic, or recyclable paper bags. The ordinance also includes a Disposable Food Ware component, which bans disposable plastic serviceware like forks, knives, spoons, and straws, as well as polystyrene foam food ware.
The County of Hawai'i also has a Single-Use Plastic Checkout Bag Ban in full effect, with all businesses, including groceries, restaurants, and farmer's markets, required to comply. This ban aims to reduce the negative impact of plastic bags on the environment, as they can entangle or choke wildlife, contribute to litter, and degrade into unsafe chemicals.
The impact of these bans has been positive, with a noticeable decrease in plastic bags along fence lines, roadsides, and in waterways and beaches. The City of Honolulu plans to conduct another waste audit in 2026 to assess the reduction in plastic bag volume and weight.
While there is still room for improvement, with plastic containers and other forms of disposable plastic not fully addressed by the bans, the measures are a proactive solution to reduce plastic waste in Hawai'i.

Plastic waste reduction initiatives
Hawaii faces several challenges in its efforts to reduce plastic waste. The state's geography and high operational costs make it difficult to establish a local recycling facility, leading to recyclables being shipped to other locations, often thousands of miles away. This process of collecting, cleaning, shipping, and repurposing recyclables contributes significantly to CO2 emissions. Additionally, the small market and high costs of real estate in Hawaii make it challenging for recycling companies to stockpile low-value plastics, further hindering recycling initiatives.
Despite these challenges, there are several plastic waste reduction initiatives underway in Hawaii. The state has implemented a plastic bag ban, encouraging the use of reusable bags instead. Over 200 restaurants in Hawaii have also pledged to become "Ocean Friendly Restaurants" by reducing their use of single-use plastics, such as foam containers, plastic utensils, and straws. Organizations like the Surfrider Foundation are driving this campaign, encouraging food businesses to voluntarily eliminate single-use plastic items from their operations.
Hawaii is also exploring innovative solutions to tackle plastic waste. New Hope Energy, one of six companies in the country, is experimenting with plastic-to-fuel technology. This process involves melting down plastic caps and lids into fuel for ships and planes. While the low price of oil currently poses a challenge to this initiative, it has the potential to be a sustainable solution for reducing plastic waste and creating a valuable resource.
Another initiative, led by Grieser, involves bringing HydroBlox machines to different communities on flatbed trucks. This "FLOW" (Factory Line on Wheels) approach aims to process plastic on-site, eliminating the need for long-distance transportation of recyclables. Additionally, the city supports source reduction, promoting the reuse of materials from demolition projects in construction through businesses like Re-use Hawaii.
Hawaii's recycling challenges and initiatives highlight the complexities of managing plastic waste in isolated communities. While economic and logistical hurdles persist, the state is actively exploring innovative solutions to reduce plastic waste and foster a more sustainable future.
