AB 2334 directs the Department of Resources Recycling and Recovery (CalRecycle) to create a temporary working group to study alternative approaches to reducing methane emissions from solid waste. The group must assess the need for and value of methods beyond current landfill gas capture and diversion programs and report findings to the director by January 1, 2029.
The bill points to an emerging landfill crisis — fires, long-term smoldering, and rapidly shrinking capacity — and ties its study to California’s existing organics and packaging laws. It requires the working group to evaluate established programs, including the Oslo, Norway model and potential carbon capture components, and the statute sunsets on January 1, 2030.
At a Glance
What It Does
The bill tasks CalRecycle’s director with standing up a multi-stakeholder working group charged with assessing alternative methane-reduction and disposal methods and the role of carbon capture technologies. The group must evaluate existing programs (explicitly naming Oslo’s program as an example) and deliver a recommendations report to the director by January 1, 2029.
Who It Affects
State and local waste managers, municipalities responsible for landfill operations, technology vendors working on carbon capture or waste-to-energy systems, and agencies implementing SB 54 (producer responsibility) and SB 1383 (organics reduction). Companies operating landfills or providing landfill-gas systems are also likely to be studied.
Why It Matters
The study could reshape California’s approach to landfill methane — potentially opening the door to alternatives that change permitting, capital investment, and long-term planning for landfills and organics processing. The report will be an evidence base that regulators and policy makers can use to consider new programs or regulatory changes.

What This Bill Actually Does
The bill creates a short-term, policy-focused mechanism inside CalRecycle to collect evidence and surface options for reducing methane from the state’s waste system. Rather than prescribing a new technology or regulation, it mandates an informed assessment: what alternative disposal or treatment methods exist, whether carbon capture is technically and economically viable at the scales California would need, and which models from other jurisdictions might translate here.
The working group’s scope is deliberately broad. It must consider alternatives in the context of California’s existing laws aimed at reducing waste and organics (SB 54 and SB 1383), which shape the volume and composition of material arriving at landfills.
The bill explicitly directs evaluators to look at international examples — the Oslo program — and to examine carbon capture as a possible component, which signals a willingness to study engineering-intensive solutions as well as programmatic changes like diversion or thermal processing.Because the statute includes a fixed reporting deadline and a sunset, the work is time-boxed: CalRecycle will need to define membership, data requirements, analytical methods, and a decision framework quickly. The likely deliverable is a set of findings on technical feasibility, cost, regulatory barriers, and recommended next steps — not an immediate regulatory change, but a roadmap that could justify follow-up rulemaking or pilot projects.
The Five Things You Need to Know
The bill requires CalRecycle’s director to establish a working group to study alternative methane-reduction methods for solid waste.
The working group must evaluate existing alternative waste disposal programs and assess potential carbon capture components, explicitly including the Oslo, Norway program as an example to study.
Findings and recommendations must be submitted to the director by January 1, 2029.
The statute includes legislative findings that cite landfill fires, long-term smoldering, and rapidly declining landfill capacity as the rationale for the study.
The entire provision is temporary: the section is repealed on January 1, 2030 (a built-in sunset after the report deadline).
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Legislative finding: landfill failures and capacity concerns
This paragraph records the Legislature’s factual predicate: landfills are experiencing fires and prolonged smoldering and available capacity is falling quickly. As a statutory finding, it frames the study as a response to an operational emergency rather than a purely academic exercise — that framing can influence how the working group prioritizes solutions that address immediate risks versus long-term policy shifts.
Legislative finding: need for study
This short clause establishes a statutory mandate to investigate the developing crisis. It does not define scope or deliverables, but it creates an explicit legislative expectation that CalRecycle will develop actionable knowledge rather than merely catalogue problems.
Creates the working group and links study to SB 54 and SB 1383
This provision directs the director to form the working group and ties its task to the assumed implementation of two major California waste laws (SB 54 on packaging and SB 1383 on organics). The linkage requires the group to evaluate alternative methane-reduction strategies in the context of these programs’ effects on waste flows and system economics — for example, reduced organics to landfills could change the cost-effectiveness of certain technologies.
Mandate to evaluate external programs and carbon-capture options
This clause requires the working group to look beyond U.S. examples and assess programs like Oslo’s, and to analyze carbon capture as a component of waste management. Practically, that means the study should cover performance data, capital and operating costs, regulatory hurdles, and site-specific suitability — not just theoretical descriptions. Naming Oslo narrows the comparative scope and signals interest in systems that pair diversion with energy or capture technologies.
Reporting deadline and automatic repeal
The working group must deliver findings and recommendations to the director by January 1, 2029, and the statutory authority for this study expires January 1, 2030. The fixed timetable forces a concentrated effort and limits the director’s discretion to extend the review without new legislation; it also means any recommended pilots or rulemakings will require separate authority or funding.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Local communities near impacted landfills — a rigorous study could produce faster, evidence-backed options to reduce fires, odors, and methane exposure, and create a basis for prioritizing interventions at high-risk sites.
- State regulators and policy makers — CalRecycle and allied agencies will receive a compiled technical and policy analysis that can streamline future rulemaking or the design of pilot projects, saving time and reducing stovepiping of technical evidence.
- Technology and service providers in carbon capture, thermal processing, and advanced waste treatment — the mandated evaluation creates visibility for these solutions and may identify opportunities for pilots or procurement if the report recommends them.
Who Bears the Cost
- CalRecycle — staff time, contracting for technical consultants, and coordination costs for running the working group and producing an analytic report fall to the agency, with no funding source specified in the bill.
- Local governments and landfill operators — they will likely need to supply data, participate in meetings, and potentially host site visits or pilots, imposing time and administrative costs.
- Taxpayers and state budget — if the report leads to pilot projects, grants, or regulatory changes, implementation will require additional funding that the bill itself does not appropriate; absent new funds, costs may be borne by local governments or private operators.
Key Issues
The Core Tension
The central dilemma is speed versus certainty: California faces pressing landfill hazards that argue for rapid intervention, but the technically and financially heavy alternatives the bill invites—thermal processing, capture, or large-scale fuel conversion—carry high upfront costs, uncertain long-term performance, and potential community impacts; the working group must decide whether to recommend pilots and fast deployment or further study to reduce the risk of costly mistakes.
The bill is narrowly procedural and avoids committing California to any particular technology or program; that restraint is both a strength and a risk. It preserves flexibility but leaves many critical choices for later—choices that will determine whether alternatives are practical at scale.
The statute names Oslo and carbon capture as focal points, but it provides no analytic standards, membership rules, data-access authority, or funding. Without those, the working group risks producing a high-level report that lacks the site-specific engineering and cost data needed to drive implementation.
Operational challenges will be significant. Comparing foreign programs to California requires normalizing for waste composition, regulatory differences, and labor and energy markets.
Carbon capture at landfill or thermal sites is nascent at scale and raises permitting, monitoring, and permanence questions. The interaction between diversion policies (SB 54, SB 1383) and infrastructure investments is another tricky area: adopting a capital-intensive technology today could become stranded if waste volumes decline as diversion succeeds.
