H-Power incinerates plastic to generate electricity
H-POWER, or the Honolulu Program of Waste Energy Recovery, is a waste-to-energy plant that has been in operation since 1990. It processes over 700,000 tons of waste annually, reducing the volume of trash taken to landfills by 90%. The facility incinerates waste, including plastics, to generate electricity for Honolulu, providing up to 10% of the island's electricity needs.
The city has an agreement to deliver 800,000 tons of trash per year to H-POWER, but they have consistently fallen short of this target, resulting in financial penalties. The plant accepts low-grade plastics (numbers 3-7) and low-value paper, such as junk mail, magazines, and telephone books, that are not recycled due to the high costs and environmental impact of shipping them off the island.
The process of incinerating waste to generate electricity is known as waste-to-energy, and it helps divert combustible materials from landfills. However, it is important to note that the burning of trash contributes to greenhouse gas emissions, which can have negative environmental consequences.
The unique location of Honolulu and the high cost of real estate present challenges for traditional recycling methods, as it is not economically feasible to stockpile large amounts of low-value plastics and other recyclables. As a result, the city's investment in waste-to-energy incineration serves as a disincentive to expanding recycling programs, despite the efforts of non-profit organizations and individuals to promote zero-waste and increase recycling rates.
Overall, H-POWER plays a significant role in managing Honolulu's waste and energy needs, but it also underscores the complex trade-offs between waste reduction, energy generation, and environmental impacts.

Honolulu doesn't recycle low-grade plastics
Honolulu's investment in waste-to-energy technology has reduced the incentive to recycle more items. The city has agreed to deliver 800,000 tons of trash a year to H-Power, an incinerator that generates 8-10% of the island's electricity. However, the city often falls short of this obligation, and has paid over $6 million in fees since 2013.
H-POWER, or the Honolulu Program of Waste Energy Recovery, was built in 1990 at the Campbell Industrial Park in Kapolei and is run by Covanta. The waste-to-energy plant processes over 700,000 tons of waste annually, reducing the volume of trash taken to the landfill by 90%. According to Markus Owens, the Department of Environmental Services public information officer, low-grade plastics (numbers 3-7) and low-value paper, such as junk mail, are not recycled on Oahu because they would need to be shipped to distant markets to be made into new products, and their low value makes this environmentally and economically unviable.
The cost and environmental impact of shipping low-quality recyclables are considered worse than the benefits of recovering energy from them at H-POWER. Instead, these items are incinerated to generate electricity.
Only a few types of plastic are recyclable on Oahu. The blue bin program, which began in 2007, allows for single-stream recycling of paper, plastic, and aluminum. However, contamination is a significant concern, with a 2016 study finding that 12-25% of collected material was contaminated. This, coupled with the high real estate prices in Honolulu, makes it difficult for recycling companies to stockpile large amounts of low-value plastics to offset the costs of collecting, sorting, and shipping them.

The city agreed to deliver 800,000 tons of trash to H-Power annually
The city of Honolulu has agreed to deliver 800,000 tons of trash annually to H-Power, a waste-to-energy plant that incinerates the trash to generate 8-10% of the island's electricity. This arrangement is part of a deal with Covanta Holding Corporation, a company specialising in energy-from-waste and industrial waste management services.
H-Power processes over 700,000 tons of waste per year, reducing the volume of trash taken to landfills by 90%. The plant accepts waste that isn't recycled or composted, including low-grade plastics (numbers 3-7) and low-value paper, such as junk mail, cereal boxes, magazines, and telephone books.
The city of Honolulu's commitment to waste-to-energy has been cited as a disincentive to increasing recycling efforts. The city regularly falls short of its 800,000-ton obligation, resulting in fees exceeding $6 million since 2013. Additionally, the limited market prices and storage space in Honolulu make it challenging to expand recycling initiatives.
The unique location of the island also presents challenges, as shipping recyclables off the island can be costly and environmentally detrimental, especially when they end up in developing countries in Southeast Asia, where waste can have harmful effects on the local environment and human health.
To address these issues, Honolulu has implemented initiatives like the HI-5 program, which offers a 5-cent deposit redemption for beverage containers, and the City & County of Honolulu is exploring options for curbside recycling.

Only a few kinds of plastic are recyclable on Oahu
Honolulu's H-POWER (Honolulu Program of Waste Energy Recovery) is a waste-to-energy plant that processes over 700,000 tons of waste annually, reducing landfill trash volume by 90%. The facility incinerates waste to generate 8-10% of the island's electricity.
However, only a few types of plastic are recyclable on Oahu. The list of acceptable plastics for recycling includes No. 1 and 2 plastics, such as plastic bottles and containers. These are considered higher-value plastics and are more commonly recycled.
Plastics with codes 3-7 are classified as low-grade and are not recycled on Oahu. This includes items like plastic bags, food tubs, hard plastic, styrofoam, and shrink wrap. The low market prices of these plastics make it uneconomical for recycling companies in Honolulu to process them. The city would need to stockpile large amounts to offset the costs of collecting, sorting, and shipping this material.
As a result, these low-grade plastics are often incinerated at H-POWER, along with other non-recyclable materials. This approach helps to reduce the amount of waste sent to landfills and provides an alternative energy source for the island.
While the recycling options for plastics on Oahu are limited, there are ongoing efforts to improve waste management practices. The HI-5 program, for example, encourages the recycling of beverage containers through a deposit redemption system. Additionally, the City & County of Honolulu is exploring options for curbside recycling to make it more convenient for residents to recycle acceptable materials.

Honolulu exports plastic waste to California and Southeast Asia
Honolulu, the capital of Hawaii, has been tackling the issue of plastic waste through various measures, including implementing some of the most restrictive plastic bans in the US. Despite these efforts, the city still struggles with managing its plastic waste, leading to the export of this waste to other regions. One of the regions that Honolulu exports its plastic waste to is California. The high real estate prices in Honolulu make it challenging for recycling companies to stockpile large amounts of low-value plastics, such as numbers 3 to 7, which are not widely recycled on Oahu. As a result, it is more economically feasible to send these plastics to California, where companies can afford to store them until market prices rise.
In addition to California, Honolulu also exports its plastic waste to Southeast Asian countries. This trend is not unique to Honolulu, as many developed countries have historically exported their waste to Asia, primarily China, for processing and disposal. However, China's decision to ban most waste imports in 2018 significantly impacted the global waste trade. The ban reduced China's plastic imports by 99% within a year, leading to a surge in plastic waste exports to Southeast Asian nations like Thailand, Malaysia, and the Philippines.
The volume of plastic waste entering Southeast Asia has been immense, with the US alone exporting over 950 million tons of plastic waste meant for recycling in 2021, much of which ended up in the region. This influx has overwhelmed Southeast Asian countries, leading to environmental concerns and social issues. The plastic waste often ends up being incinerated or dumped into waterways, causing air and water pollution. Additionally, the presence of illegal waste dumping and mislabeled garbage exacerbates the problem, as Southeast Asian governments struggle to regulate and manage the influx of foreign waste.
While Honolulu's efforts to reduce plastic consumption and increase recycling are commendable, the city's limited space and market dynamics pose significant challenges. The export of plastic waste to California and Southeast Asia highlights the interconnectedness of the global waste trade and the need for collaborative solutions to address the plastic pollution crisis.
