How TBI cut waste data processing time and gained audit ready insight across a decentralized construction group
How one of the Netherlands' largest construction groups standardized waste data across subsidiaries, cut reporting effort, and shifted conversations from data validation to action.
Client overview
Waste management is a material topic for TBI. Rising material costs, stricter national waste legislation, and upcoming CSRD requirements necessitate that waste data be accurate, comparable, and defensible across projects, subsidiaries, and reporting levels. Four TBI subsidiaries, including Struijk, Hazenberg, Koopmans, and JP van Eesteren, currently use geoFluxus.
The challenge
Before geoFluxus, waste data at TBI was managed locally by each subsidiary. In practice, this meant:
- Waste invoices, weighbridge tickets, and contractor reports processed manually
- Different formats, classifications, and levels of detail per subsidiary
- Limited comparability between projects and business units
- High effort at holding level to consolidate data for audits and reporting
- ESG discussions focused on whether the data was correct, rather than what to improve
At the subsidiary level, teams spent disproportionate time collecting and checking data. At the holding level, sustainability and QHSE teams lacked a single, trusted overview of waste streams and treatment routes.
The solution
geoFluxus was implemented to centralise, verify, and standardise waste data across participating TBI subsidiaries.
How the project worked in practice
- TBI subsidiaries shared existing waste inputs such as invoices, weighbridge tickets, and contractor reports, without changing on-site processes
- geoFluxus ingested these inputs
- The processed data was made available through a dynamic platform with dashboards and exports tailored to subsidiary teams and holding-level reporting needs, easily identifying optimizations and subsidiary unique waste opportunities while creating a single, comparable overview for the holding.
This created a continuous data flow from operational waste documentation to audit-ready, group-level insight.
Key capabilities used by TBI
- Standardized waste classification across subsidiaries and projects
- Data verification and enrichment, including cross checks where applicable
- Audit ready outputs for CSRD, ISO 14001, and internal reporting
- Dashboards and exports for both subsidiary level and holding level views
The result: one consistent data model that works for operational teams on site and for group level reporting and governance.
Results Framework: What geoFluxus delivered at TBI
1. Efficiency and productivity: From manual consolidation to reporting control
Before geoFluxus, waste data collection and consolidation was largely manual. Subsidiaries processed invoices and tickets locally, while both subsidiaries and holding-level teams spent weeks reconciling formats, classifications, and gaps for audits and reporting.
With geoFluxus in place:
- Waste invoices and documentation are processed automatically and refined consistently
- Data is standardized across subsidiaries and projects
- Reporting outputs for CSRD, ISO 14001, and internal reviews can be generated centrally
What this delivered at TBI
- ~10 minutes per waste invoice processing time at TBI Struijk
- Significantly reduced manual reporting effort at holding level
- Faster decision cycles across QHSE, Procurement, and Sustainability
- Higher trust in data quality and fewer internal validation loops
geoFluxus also enables up to 90% time savings on waste data collection and compliance reporting as coverage expands across subsidiaries.
2. Cost impact: creating leverage in a traditionally opaque spend category
Waste costs in construction are often treated as fixed and difficult to influence, especially in decentralised organisations with multiple contractors and processors. geoFluxus delivers TBI a consolidated, comparable view of waste volumes, treatment routes, transport distances, and processor performance across entities.
What this delivered at TBI
- Insight into transport kilometres and associated costs
- A factual baseline to support waste processor contract discussions
This shifted waste from an administrative cost to a category where Procurement can negotiate based on data rather than assumptions, improving leverage with vendors over time.
3. Sustainability and ESG impact: defensible data for CSRD and circularity targets
For TBI, the primary ESG challenge was data credibility. Without consistent classifications and verified treatment routes, sustainability metrics were difficult to defend. geoFluxus standardized waste data across subsidiaries and enriched it where applicable with governmental reference data.
What this delivered at TBI
- Consistent recycling, landfill, and incineration percentages across entities
- Clear separation performance by stream and project
- Lower incineration and landfill volumes visible at group level
This delivers a reliable baseline for CSRD disclosures under ESRS E5 and for steering circularity initiatives with confidence.
4. Revenue enablement: strengthening tender competitiveness
In construction, sustainability performance increasingly influences tender outcomes, especially in public and large infrastructure projects. With geoFluxus, TBI can support sustainability claims with consistent, auditable waste data rather than project-specific estimates.
What is possible for TBI
- A stronger factual basis for ESG sections in tenders
- Improved readiness where waste performance is a prerequisite for market access
- The ability to track tender win-rate uplift where sustainability is scored
5. Risk, compliance, and resilience: fewer audit surprises
geoFluxus produces audit-ready waste outputs automatically, reducing dependency on last-minute data collection and manual reconciliation.
What this delivered at TBI
- Structured, repeatable outputs for CSRD, ISO 14001, and national requirements
- Lower perceived compliance risk during audits
- Smoother audits with fewer exceptions and follow-up questions
- Platform reviewed with auditors regarding specific questions, creating trust in the reporting process, quality, and chain of custody regarding waste data
6. Stakeholder experience and adoption: one source of truth across the group
geoFluxus is used by both local subsidiaries and holding-level teams, with dashboards and exports tailored to different roles.
What this delivered at TBI
- More stakeholders informed through shared dashboards and reports
- Higher confidence in waste-related decisions
- Broad adoption across subsidiaries, HQ, and project teams
This delivers a reliable baseline for CSRD disclosures under ESRS E5 and for steering circularity initiatives with confidence.
The biggest win
Instead of debating numbers, teams now focus on concrete improvement actions such as treatment routes, separation performance, and supplier discussions. Or identifying outliers in their processes and identifying streams that are processed below industry standards.
What surprised TBI most
Internal discussions moved away from validating data and towards deciding what to improve.
“Geofluxus significantly simplifies our reporting process. TBI and its subsidiaries extract more actionable information from the waste reports, allowing waste streams to be processed more sustainably."
This shift marks a turning point: waste data is now something teams can actively steer on, not just report.
Why this matters for construction companies
For decentralised construction groups, waste data is often one of the hardest ESG topics to control. Projects, contractors, and subsidiaries all generate data but without standardisation, insight gets lost. This case shows that with verified, centralised waste data:
- Reporting effort drops without sacrificing audit confidence
- ESG metrics become comparable across projects and entities
- Procurement and sustainability teams gain a shared factual baseline
