The Global Imperative

70% of the world's 2.1 billion tonnes of annual municipal waste ends up in landfills. These sites release approximately 100 million tonnes of climate-warming methane each year, making them one of the largest anthropogenic sources of greenhouse gas emissions.

Less than 25% of landfills worldwide capture their gas, and even fewer upgrade it to generate power or renewable natural gas. Small- and medium-sized sites with installed gas capture systems often shut down after a few years due to missing funding and laxly enforced regulations, causing operational and maintenance budgets to disappear.

The Vision

Mission Statement

Make continuous, high-quality methane abatement universal — no matter a landfill's size, location, or budget.

Standardised Project Development

Landfill gas projects follow well-understood processes and methodologies worldwide. This means Project Development Documents and their validation can be streamlined and simplified, drastically reducing time-to-market for smaller operators.

Digital Measuring, Reporting and Verification

TrustVal's dMRV-as-a-Service platform provides standardized, secure, automated digital processes that slash compliance costs for initial registration and continuous verification, while speeding up carbon payouts to project operators.

Carbon-Backed Cashflow

Near real-time issuance of emission-reduction certificates secures long-term operational and maintenance funding — ensuring landfill gas systems keep running year after year.

Always-On Performance

Predictive analytics keep gas systems running continuously, maximising climate impact and return on investment for every participating site.

Analysing the Value Streams

A typical landfill site with 2.5 million tonnes of waste generates approximately 2,700 Nm³/h of landfill gas for around 10 years. This creates two parallel revenue streams that together make the project financially sustainable.

Electricity generation: A 2 MWh capacity installation produces around 70 GWh/year, generating approximately 3 million EUR annually on the electricity market.

Carbon market revenue: The same site produces around 120,000 tCO₂e in annual emission reductions, worth approximately 3 million EUR/year on the carbon market — effectively doubling the project's revenue potential.

Results

Addressing a Growing Global Challenge

TrustVal addresses the global waste and methane crisis by automating the generation of landfill methane carbon credits, significantly reducing verification costs and enabling more and smaller landfill operators to efficiently capture, use and monetize landfill gas.

From Decades of Experience to Digital Future

With five decades of experience in building landfill gas flares, TrustVal is now driving digital transformation through its innovative cloud-based digital monitoring, reporting and verification (d-MRV) as a Service, revolutionising the registration and certification process for greenhouse gas emission reductions.

Democratising Access to Carbon Finance

By digitally streamlining registration and certification, TrustVal enables a significant number of previously excluded landfills to utilise the potential of carbon markets, incentivising the combustion and productive use of landfill gas and turning waste into valuable environmental and economic benefits — while reducing greenhouse gas impact manyfold.

2035 Target

Enable 1,000 landfills to stay online, prevent 100 Mt CO₂e cumulative emissions, and channel $300 million back into local waste infrastructure.
