Deploying TrustVal's dMRV system at a landfill in Chile's Valparaiso Region to collect real-time landfill gas data and automate compliance reporting under Chilean environmental regulations.
Landfill operators in Chile face a dual burden: they must comply with an increasingly stringent regulatory framework — including DS N° 189/2005, Resolution Exenta N° 254/2020, and RCA (Environmental Qualification Resolution) conditions — while also seeking to monetize methane destruction through carbon credit markets.
The Superintendencia del Medio Ambiente (SMA) requires continuous environmental monitoring data transmitted via its secured API at conexiones.sma.gob.cl. Traditional approaches rely on manual data collection, spreadsheet-based reporting, and periodic filings — creating compliance risk, delayed submissions, and human error in a process that demands precision.
At the landfill site in the Valparaiso Region, the operator needed a system that could handle both obligations simultaneously: real-time regulatory compliance and verified carbon credit generation from the same monitoring infrastructure.
TrustVal's digital Measuring, Reporting and Verification (dMRV) system connects directly to the existing gas extraction and flaring instrumentation at the site. The system captures seven key parameters every five minutes, 24 hours a day, building a comprehensive dataset for both compliance and carbon credit verification.
Sensor data flows from the landfill's instrumentation through an encrypted cloud pipeline to TrustVal's dMRV platform. The system uses paginated API fetching in 3-day chunks to ensure no readings are lost, even during connectivity interruptions. Each data point receives a cryptographic timestamp at the point of capture, creating an immutable audit trail that satisfies both SMA inspections and carbon credit verification audits.
From the raw sensor data, TrustVal's platform automatically computes key operational and environmental metrics in real time. The Methane Destruction Rate is calculated from the volume flow and methane concentration, while CO₂ equivalent avoided uses the IPCC AR5 global warming potential factor of 28 for methane. These derived values feed directly into both the compliance reporting stream and the carbon credit quantification process.
The Valparaiso plant dashboard provides operators with full visibility into their landfill gas extraction system. The dashboard displays the latest sensor readings, accumulated CO₂e avoided, methane destruction rates, gas composition breakdowns, and historical trends — all updated in real time from live API data. Operators can filter by time period and drill into daily records for detailed analysis.
Chile's environmental regulatory framework requires landfill operators to submit continuous monitoring data to the SMA. TrustVal automates this entire process, eliminating the risk of missed filings and ensuring data reaches the regulator in real time.
Sensor data is transmitted directly to conexiones.sma.gob.cl via secured API — no manual uploads, no delay, no risk of human error in regulatory filings. The same monitoring infrastructure that keeps you compliant also generates verified carbon credits.
The TrustVal platform maps directly to Chile's landfill gas regulatory obligations. Real-time environmental monitoring data is already fully automated under Resolution Exenta N° 254/2020, with additional reporting modules on the roadmap.
| Reporting Obligation | Legal Basis | Frequency | Authority | Status |
|---|---|---|---|---|
| Real-time Environmental Monitoring Data | Resolution Exenta N° 254/2020 | Continuous | SMA | Automated |
| Monthly Operational Reports (SEREMI) | DS N° 189/2005, Art. 47 | Monthly | SEREMI Salud | Roadmap |
| Waste Declarations (SINADER/RETC) | DS N° 1/2013 (MMA) | Semi-annual | MMA / SMA | Roadmap |
| Groundwater Monitoring | DS N° 189/2005, Art. 41 | Quarterly | SMA | Roadmap |
| Contingency Reports | RCA Conditions | Event-based | SMA | Roadmap |
| Methane Emissions Certification | DS N° 189/2005, Art. 49 | Annual | SMA | Roadmap |
When methane readings approach the 25% LEL (Lower Explosive Limit) threshold defined in DS 189 Art. 49, operators are alerted instantly — giving the team time to act before it becomes a regulatory finding. This proactive monitoring transforms compliance from a reactive obligation into an active safety system.
The same monitoring infrastructure that keeps the operator compliant also generates verified carbon credits. The dMRV platform quantifies methane destruction using internationally recognised methodologies, producing emission reduction certificates that unlock a second revenue stream from the carbon market — effectively letting the compliance investment pay for itself.
The TrustVal dMRV system at the Valparaiso site has been collecting continuous sensor data since December 2025, accumulating over 17,900 readings across all monitored parameters. The system operates around the clock with 5-minute measurement intervals, providing comprehensive coverage of the landfill's gas extraction operations.
Based on live sensor data, the site has avoided over 84 tCO₂e in its first months of operation. Each tonne of CO₂ equivalent avoided is backed by cryptographically timestamped sensor readings, providing an audit trail from raw measurement to certified emission reduction.
Since deployment, the real-time monitoring data stream to the SMA has operated without manual intervention. Environmental data flows automatically from the landfill sensors through TrustVal's encrypted cloud to the regulatory authority's API — eliminating the spreadsheets, manual uploads, and deadline anxiety that previously defined the compliance process.
The Valparaiso Region deployment demonstrates that a single dMRV infrastructure can simultaneously address regulatory compliance and carbon credit generation. By digitising the entire measurement-to-reporting chain, operators eliminate manual processes, reduce compliance risk, and unlock new revenue — all from their existing gas extraction equipment.
