Households relocating to Oahu from the mainland often notice a difference at the takeout counter within hours of landing. Plates arrive as molded fiber, drink lids come without straws unless requested, and the familiar clamshell of white foam is missing. That change traces to Honolulu Bill 40, codified as Revised Ordinances of Honolulu (ROH) Chapter 41A, which the City and County of Honolulu enacted in December 2019 and phased in through 2022 and 2024.
The ordinance banned polystyrene foam food service containers, restricted single-use utensils and straws to on-request distribution, and extended the ban to most non-compostable plastic containers by January 2024. Violations carry civil penalties of $100 to $1,000 per day per violation. The rules apply to any food vendor operating within the City and County of Honolulu, which covers the entire island of Oahu.
The approach differs from Maui County’s Ordinance 5267 and Hawaii County’s polystyrene rules under Chapter 22 of the Hawaii County Code. Anyone opening a restaurant, running a food truck, or ordering takeout on the islands should understand which rules apply where, what qualifies as compliant packaging, and how enforcement is being carried out by the Department of Environmental Services.
What Bill 40 Actually Does
Bill 40 (CD2, FD1) was passed by the Honolulu City Council on December 4, 2019 and signed by Mayor Kirk Caldwell shortly after. The measure amended the ROH by adding Chapter 41A, titled “Disposable Food Ware.” Its purpose was to reduce plastic waste entering Oahu’s landfill at Waimanalo Gulch and the coastal environment, both of which the Council identified as receiving heavy loads of takeout packaging.
The chapter regulates three categories of foodware: expanded polystyrene (Styrofoam) containers, single-use plastic service ware such as utensils and straws, and disposable plastic food containers that are not compostable. Each category has its own compliance date, its own definition, and its own list of exemptions written into the ordinance text. Vendors are responsible for compliance; the ordinance does not fine individual customers.
Enforcement authority sits with the City’s Department of Environmental Services, which can issue notices of violation, impose civil fines, and pursue injunctive relief in Hawaii state court. The department’s phased rollout used an initial warning period before monetary penalties began, which gave restaurants a runway to draw down existing inventory. That inventory allowance was explicit in the ordinance and was not a discretionary grace period.
Who is covered
Coverage extends to every “food vendor” doing business inside the City and County of Honolulu. That includes brick-and-mortar restaurants, coffee shops, food trucks, caterers, hotel food and beverage operations, school cafeterias run by contractors, and grocery deli counters. The ordinance treats prepared foods sold for immediate consumption differently from packaged foods sold sealed on shelves, which fall outside 41A.
What “disposable” means here
The ordinance defines disposable service ware as items designed for single use, then thrown away, composted, or recycled. Reusable dishware washed and reused on-site is not regulated. That distinction matters for cafes that offer a dine-in option: ceramic plates and metal flatware for eat-in service are unaffected, while the takeout containers used for the same food must meet 41A standards.
Timeline of the Phase-In
The Council structured Bill 40 in two compliance waves so vendors could plan inventory and supplier changes. COVID-19 disruptions pushed the first wave from January 1, 2021 to April 1, 2022, with a Council amendment approved in late 2020. The second wave landed on January 1, 2022, and a further clarification on non-compostable containers took effect January 1, 2024.
| Date | Rule | Applies to |
|---|---|---|
| January 1, 2022 | Polystyrene foam foodware banned | All food vendors |
| April 1, 2022 | Utensils/straws upon request only | All food vendors |
| January 1, 2024 | Non-compostable plastic containers banned | All food vendors |
| Initial warning window | Notices only, no monetary fine | ~90 days per wave |
| Fine window | $100-$1,000 per day/violation | After warning ends |
The two-wave design was intentional. Polystyrene has close substitutes (molded fiber, PET, PLA-lined paper) that were already common in mainland cities, so the first ban was seen as easier for suppliers. Non-compostable plastic clamshells and lids required deeper supply-chain changes, so those got an additional two years. Vendors that stocked non-conforming supplies before the deadline could use existing inventory only through a short exhaustion window.
The COVID-19 postponement carried real cost for supply-chain planning. Suppliers that had ramped up fiber and PLA production faced a demand crash in spring 2020, and inventory sat on ships and in warehouses through 2021. When April 2022 arrived, some Oahu vendors had already switched voluntarily during 2020 and 2021, while others waited until the last month. That split shows in Department of Environmental Services warning data from the first inspection cycle.
The 2024 phase caught more small operators unprepared. Chain restaurants had corporate suppliers and central purchasing that could pivot in months, but independent shops that had drawn down foam inventory in 2021 sometimes rebuilt stocks with cheap non-compostable PET as an intermediate substitute. Those PET stockpiles then needed to be discarded or rotated out during 2023 to meet the January 2024 deadline, adding a second wave of unplanned expense.
The Polystyrene Ban Explained
Since January 1, 2022, ROH 41A has prohibited the sale, distribution, or use of expanded polystyrene foam food service ware by any food vendor. That covers clamshell containers, cups, plates, bowls, trays, and hinged boxes, whether printed with a logo or blank. Foam meat trays sold at grocery butcher counters were the largest carve-out during rulemaking, and the final version still exempts raw or butchered meat, poultry, and fish packaging.
Foam ice chests, packing peanuts, and shipping insulation are outside 41A because they are not food service ware. So are foam coolers sold in retail, though a separate Hawaii state solid waste discussion has looked at those. Vendors that continue to offer foam takeout containers after the effective date can be cited on the first inspection, though enforcement staff generally issued written warnings first when the ordinance was new.
Approved substitutes
- Molded fiber (bagasse) clamshells made from sugarcane pulp
- Uncoated or PLA-lined paperboard boxes and cups
- Aluminum foil trays with cardboard lids
- Palm-leaf plates for catering and buffet-style service
- Reusable rigid containers offered by return-and-refill programs
Restaurant operators reported per-unit cost increases of roughly 20 to 60 percent when switching from foam clamshells to molded fiber or paperboard, based on Hawaii Restaurant Association surveys reported by the Honolulu Star-Advertiser. That premium has narrowed as more mainland suppliers ship fiber to the Pacific through Matson and Pasha Hawaii. Bulk orders now land at pricing closer to legacy foam.
Utensils, Straws, and Stirrers Upon Request
The upon-request rule went live April 1, 2022 after the COVID-era postponement. Under it, food vendors may not include plastic utensils, straws, splash sticks, condiment packets, or napkins with any takeout order unless the customer specifically asks. Drive-through and delivery orders also fall under the rule, which meant delivery apps like DoorDash and Uber Eats had to add a checkbox on Honolulu menus.
The intent was to cut default distribution. Prior audits by the Department of Environmental Services estimated that up to 40 percent of plastic utensils bundled with delivery orders went to trash unused. Under the ordinance, straws for people with disabilities are always available on request, and the ordinance specifically states that vendors cannot require a customer to justify a straw request. That protection was added after disability advocates raised access concerns.
What “upon request” actually means
Compliance requires the customer to initiate the request either verbally, through a mobile order checkbox, or by selecting an option at a self-service kiosk. Passive availability like a countertop bin of straws customers can grab does not violate the ordinance, provided vendors do not add items to the bag by default. Restaurants that automatically drop a utensil pack into every delivery bag are technically in violation.
The 2024 Non-Compostable Container Expansion
The most significant expansion took effect January 1, 2024, when ROH 41A began prohibiting single-use plastic food containers that are not compostable. That covered PET clamshells, polypropylene bowls with plastic lids, plastic cutlery kits, and most plastic-lined paper cups if the lining was not certified compostable. Rigid plastic lids on drink cups became a compliance focus because many major chain suppliers had not yet certified them under ASTM D6400.
A container qualifies as compostable if it meets ASTM D6400 or ASTM D6868 standards, verified by the Biodegradable Products Institute (BPI) or a comparable certifier. The label matters: vendors must be able to show inspectors either the certification mark on the packaging or documentation from the supplier confirming compliance. Products labeled “biodegradable” without ASTM certification do not count. That distinction has tripped up vendors relying on vague marketing claims.
Oahu’s ability to actually compost these containers is limited. The island has no municipal industrial composter accepting ASTM D6400 packaging at scale, so most certified compostable clamshells end up in the H-POWER waste-to-energy plant or Waimanalo Gulch landfill. The Council was aware of that gap when it passed the expansion, but treated the compostable requirement as a first step toward eventual composting infrastructure.
Exemptions and Waivers
ROH 41A carves out several categories that stay outside the ban. Meat, poultry, and fish trays used for raw product at grocery counters remain permitted. Prepackaged foods that arrived at the store already sealed in plastic (potato chips, yogurt cups, single-serve nut packs) are not covered, since the ordinance targets what vendors dispense, not what manufacturers ship. Emergency food distribution during declared disasters is also exempted.
Vendors that can demonstrate financial hardship or unavailability of compliant alternatives can apply for a waiver from the Department of Environmental Services. Waivers run for up to 12 months and are renewable. Applications require documentation of the specific product, evidence that compliant alternatives are unavailable or cost more than a defined threshold, and a compliance plan for eventual transition. Approvals were granted more readily during the first year than they are now.
The waiver process requires a written application submitted with supporting documentation. Applicants must specify the item, describe alternatives evaluated, provide price comparisons with certified compliant products, and outline a transition plan. Waivers granted are public records under Hawaii’s Sunshine Law. Denied applications can be appealed within 30 days of the written denial, though appeals are rare relative to the total number of vendors covered.
Categories excluded from 41A
- Raw meat, poultry, and seafood trays at grocery butcher counters
- Sealed prepackaged foods (chips, nuts, yogurt) made off-site
- Emergency food during Governor-declared disasters
- Foam shipping insulation, coolers, and packing peanuts (not foodware)
- Reusable rigid ware for dine-in or refill programs
Penalties and Enforcement
Civil fines run from $100 for a first violation to $1,000 per day for continuing violations after multiple notices. The Department of Environmental Services issues a notice of violation with a compliance deadline (typically 30 days) before assessing fines. Fines accrue per day per violation type, so a vendor still handing out foam clamshells and unrequested plastic utensils could face stacked penalties.
| Violation stage | Fine amount | Timing |
|---|---|---|
| First notice of violation | $100 | Written warning, 30-day cure |
| Second violation | $250 | Any repeat within 12 months |
| Third violation | $500 | Any repeat within 12 months |
| Continuing violation | $1,000 per day | Uncured after final notice |
| Injunctive relief | Court-ordered halt | Persistent non-compliance |
Enforcement inspections are complaint-driven and routine. Members of the public can file a complaint through the City’s 311 system or directly with the Department of Environmental Services. Inspectors may visit unannounced during business hours, sample packaging, and photograph noncompliant items. In practice, larger chain restaurants have drawn the most attention because their supply changes are visible and their menu items are audited more often than small counter-service shops.
The Department’s early enforcement posture was educational. The first year saw thousands of warnings but only a small number of monetary fines. That approach shifted after January 2024 as the non-compostable container ban took effect, and vendors that had multiple warnings in the first phase started to see actual fines under the second phase.
How Maui County Ordinance 5267 Compares
Maui County passed Ordinance 5267 in 2022, which addressed polystyrene foam foodware and disposable service ware similarly but with different definitions and a separate compliance schedule. The Maui ordinance amended Title 20 of the Maui County Code and applied to Maui, Molokai, and Lanai (all part of Maui County). Households considering a move to Maui or upcountry Kula should note the differences.
Maui’s rule bans polystyrene foam foodware and requires disposable service ware to be recyclable or compostable. It also uses the upon-request model for utensils and straws. The definitions of “compostable” and the certification standards accepted are close to Honolulu’s but not identical, and Maui’s penalty schedule tops out at $500 per day rather than $1,000. That gap matters mostly to chains that operate on both islands.
| Feature | Honolulu ROH 41A | Maui Ord. 5267 | Hawaii County Ch. 22 |
|---|---|---|---|
| Polystyrene ban effective | Jan 1, 2022 | Mar 31, 2023 | Jul 1, 2019 |
| Non-compostable plastic containers | Banned Jan 1, 2024 | Recyclable OR compostable | Not explicitly banned |
| Utensils upon request | Yes, Apr 1, 2022 | Yes, on request | Yes |
| Max daily fine | $1,000 | $500 | $1,000 |
| Meat tray exemption | Yes | Yes | Yes |
| Enforcement agency | Env. Services | Dept. of Env. Mgmt. | Dept. of Env. Mgmt. |
Hawaii County’s Foodware Rules
Hawaii County (the Big Island) was actually the first Hawaii county to ban polystyrene foam food service ware, with Bill 40-15 taking effect July 1, 2019. That rule sits in Chapter 22, Article 5 of the Hawaii County Code and covers foam clamshells, cups, trays, plates, and bowls. It preceded Honolulu’s ordinance by more than two years, though the Big Island rule stopped at polystyrene and did not extend to all non-compostable plastic containers.
Hawaii County’s penalties align with Honolulu’s at up to $1,000 per day, but enforcement is handled by the county’s Department of Environmental Management. The Big Island’s rural geography and dispersed food-vendor base made enforcement slower to ramp up than on Oahu. Household visitors to Kailua-Kona, Hilo, or the Puna District will find foam takeout containers scarce but not extinct at every small vendor, particularly at temporary food-truck operators servicing rural events.
The Big Island’s earlier lead reflected local advocacy. The Kohala Center and West Hawaii Community Health Center pushed for the 2018 measure after documenting foam waste on shorelines from Puako to Punaluu. The county Council passed the bill unanimously. Enforcement has been slower than on Oahu because the Department of Environmental Management has a smaller inspection budget spread across a much larger geographic area than the compact urban Honolulu inspectorate.
Kauai has considered similar legislation but has not enacted a countywide plastic foodware ordinance as comprehensive as Bill 40 or Ordinance 5267 through late 2025, though a separate polystyrene foam ordinance passed there earlier. County-level differences matter to any hospitality or catering business operating across islands, since suppliers often ship the same product line to all four counties.
Impact on Delivery Apps and Food Trucks
Third-party delivery platforms have had to adjust their Oahu operations in ways that go beyond a checkbox. DoorDash, Uber Eats, and Grubhub add a utensils-request toggle on menus for Honolulu-area restaurants, defaulting to “no utensils.” Restaurants receiving these orders must not add utensils unless the toggle is on. Some kitchens had to update packing station signage and retrain staff who had operated on autopilot.
Food trucks and pop-up vendors face compliance too. The Department of Environmental Services has explicitly held that mobile food operators are food vendors under 41A. Inspectors have visited farmers markets, beach-park events, and the parking-lot food-truck rows at Kakaako and Kailua to sample packaging. Trucks that operate at festivals must swap foam trays and unrequested utensil packs even for one-day events, subject to the same fines as brick-and-mortar shops.
Catering operators serving corporate lunches, weddings, and school events also fall under the ordinance. The rule applies to the moment food is served to the individual eater rather than to the volume purchase from a caterer. A single bulk hot pan is exempt because it is not disposable service ware, but the individual plates and utensils handed out are covered. Buffet setups have shifted toward compostable palm-leaf plates and bamboo utensils.
Practical Guidance for New Residents and Businesses
For a household newly moved to Oahu, the ordinance changes takeout in visible ways. Order a plate lunch at a Kaneohe drive-in and the container will be molded fiber. Order poke from a Chinatown counter and the bowl will be paperboard or PLA-coated. Delivery orders arrive without a fistful of plastic forks unless the app checkbox for utensils is ticked at ordering time.
New restaurant owners face a bigger learning curve. Sourcing compliant packaging is now standard through Oahu-based restaurant supply houses, but pricing changes as certification standards evolve. Owners should factor a 25 to 40 percent packaging cost premium into pro forma budgets compared with pre-2022 foam. That figure includes labor to train staff on the upon-request protocol at the counter, which is a common source of first-notice violations.
Anyone opening a food business should coordinate with the Hawaii Department of Health for food-safety permitting alongside the packaging compliance check. State health rules are separate from ROH 41A, and inspectors from both agencies may visit the same establishment during a startup period. Business licensing through the City and County of Honolulu also requires disclosure of the type of foodware being used, per updates made after Bill 40.
Household-level takeaways
- Ask for utensils only when actually needed at pickup
- Bring a reusable clamshell to farmers markets and refill counters
- Check delivery app checkboxes for utensils, straws, condiments
- Look for BPI or ASTM D6400 marks on takeout containers you compost
- Remember foam is banned but not always fully absent yet
Cost context for the switch
The packaging cost jump has been one factor in menu-price creep at Oahu takeout counters. It combines with grocery inflation tracked in Hawaii’s Honolulu CPI and the high underlying cost of electricity in Hawaii that drives commercial kitchen expenses. Households comparing takeout prices with mainland norms should expect a persistent premium, though the packaging share is smaller than labor, rent, or utility inputs.
Where the Rules May Head Next
The Honolulu City Council has floated additional amendments to ROH 41A since 2024, including tighter definitions of compostable certification and possible extension to plastic beverage bottles or foil-lined coffee pods. None of these were enacted as of mid-2025. State-level bills at the Hawaii Legislature have proposed a statewide floor that would harmonize county rules, but those have not passed either. Reporting on the debate has been steady in the Honolulu Civil Beat and Hawaii News Now.
The Department of Environmental Services publishes updates and vendor guidance on the City’s website. Businesses should track that page annually because the certification-standard list can change as new ASTM revisions are adopted. Households should watch for possible expansions to items like plastic-lined paper coffee cups, which have been discussed but not yet regulated under 41A.
How This Fits Into Living on Oahu
Bill 40 sits in a broader stack of Honolulu land-use, tax, and daily-life rules that new residents run into. Homeowners will encounter the owner-occupant property tax exemption and accessory dwelling rules. Commuters will use the Skyline rail. Renters will price rooms against the current Hawaii rent market, and everyone will notice foodware differences within days.
The plastic foodware rule is smaller than most of those other systems, but it changes daily behavior in a visible way and affects business costs at every corner deli. That makes it worth understanding early rather than after a first business inspection or a first delivery-order surprise upon arrival on the island.
Frequently asked questions
Is polystyrene foam completely banned for restaurants on Oahu?
Yes, for food service use since January 1, 2022 under ROH 41A. The ban covers foam clamshells, cups, plates, bowls, and hinged boxes distributed by any food vendor operating within the City and County of Honolulu. Foam meat trays at grocery butcher counters and non-food packaging like coolers and shipping insulation remain permitted.
Do restaurants automatically include utensils with takeout orders?
No, not since April 1, 2022. The upon-request rule requires customers to specifically ask for plastic utensils, straws, stirrers, condiment packets, or napkins before vendors can include them. Delivery apps must show a checkbox on Honolulu orders. Straws are always available on request for people with disabilities without any need to justify the request.
What happens if a restaurant is caught violating the ordinance?
The Department of Environmental Services issues a written notice of violation for a first infraction, giving a 30-day cure period. Repeat violations trigger fines of $250 and $500, with continuing violations reaching $1,000 per day. Enforcement is complaint-driven, and members of the public can file reports through the City’s 311 system.
How is Maui County’s plastic foodware ordinance different?
Maui’s Ordinance 5267 bans polystyrene foam and requires disposable service ware to be recyclable or compostable, but Maui’s polystyrene ban took effect March 31, 2023, later than Honolulu’s. Maximum daily fines top out at $500 rather than $1,000. Vendors that operate on both islands must comply with the stricter Honolulu standards while on Oahu and Maui rules while on Maui, Molokai, or Lanai.
Was the Big Island the first county to ban plastic foam foodware?
Yes. Hawaii County (the Big Island) enacted Bill 40-15 in 2018 with an effective date of July 1, 2019, more than two years before Honolulu’s ban took effect. The Big Island rule under Chapter 22, Article 5 stopped at polystyrene foam and did not expand to all non-compostable plastic containers the way Honolulu’s 2024 update did.
Do groceries and prepackaged foods change under Bill 40?
Not for prepackaged items sealed off-site: chips, yogurt, cheese, and packaged nuts stay legal. Prepared deli and hot bar items sold at the grocery counter fall under 41A and should now come in molded fiber, paperboard, or certified compostable containers. Reusable produce bags and clamshells are welcome at farmers markets and many grocery stores.
Can vendors get a waiver if compliant packaging is unavailable?
Yes. The Department of Environmental Services accepts waiver applications for up to 12 months, renewable. Applicants must document that no compliant alternative exists or that available alternatives exceed cost thresholds. Waivers are more likely to succeed for niche items like specific hot-drink lids than for common categories like clamshells, which have widely available substitutes.
