# Green infrastructure and urban forestry Structural soil cells, professional urban-forest management services and moss-based biofiltration installations that let street trees and green infrastructure survive and function under paved urban surfaces — the hardware and service layer distinct from stormwater bioretention systems, which target runoff specifically. Source: https://en.bioecon.ru/technology/green-infrastructure-urban-forestry/ Updated: 2026-08-18 ## Overview and value chain Markers: [EC: US EPA green infrastructure guidance + EU urban greening strategy under the biodiversity framework | OECD: Sustainable land use | Regulator: EPA (USA), REACH framework (EU)] Green infrastructure and urban forestry covers the hardware and service layer that lets trees and vegetated systems survive and function inside a paved, compacted urban environment — structural soil cells that give tree roots uncompacted growing space beneath a sidewalk or plaza, professional tree-care and canopy-management services, and moss-based biofiltration units that add urban air-quality function to a streetscape installation. A modern interlocking soil-cell system replaces the compacted fill that would otherwise crush tree roots with a load-bearing structural frame, so pavement above carries traffic loads while the soil below stays uncompacted and root-hospitable. The category is distinct from stormwater bioretention systems, which are engineered specifically to filter runoff before it reaches waterways: green infrastructure and urban forestry is oriented around tree survival, canopy growth and the broader ecosystem-service function of urban vegetation (shade, air quality, biodiversity) rather than a single water-quality outcome. It spans structural soil-cell hardware for tree pits, ongoing urban-forest management delivered as a professional service, and emerging biofiltration installations that combine living moss with sensor-driven airflow to target localized air pollution. The key directions of green infrastructure and urban forestry are: 1. **Structural soil cells:** interlocking, load-bearing frames create uncompacted root-growing space beneath paved surfaces, letting street trees establish and mature in locations that compacted urban fill would otherwise prevent. 2. **Professional urban-forest management services:** long-term tree care, soil research and canopy-management services delivered as an ongoing service relationship rather than a one-time installation. 3. **Underground tree-pit construction systems:** combined structural support, root space and water management delivered as a single integrated tree-pit product for paved streetscapes. 4. **Moss-based air-quality biofiltration:** living moss combined with sensor-driven airflow technology targets localized urban air pollution, adding an air-quality function to green-infrastructure installations beyond tree canopy alone. ### Sectoral value chain ``` [Streetscape/paved site design] ──> [Structural soil cell / tree-pit installation] ──> [Tree planting] │ (canopy establishment) │ ▼ [Ecosystem-service function] <─── [Ongoing management service] <─── [Growth monitoring] ``` ### Value chain levels | Level | Description | Key inputs/outputs | |:---|:---|:---| | **Structural soil-cell manufacturing** | Interlocking, load-bearing frame units are manufactured to a defined structural-loading specification. | **In:** structural cell components. **Out:** manufactured soil-cell units. | | **Site design and specification** | Landscape architects and engineers specify the soil-cell system, tree-pit configuration and species selection for a given streetscape or plaza. | **In:** site constraints, structural requirements. **Out:** installation specification. | | **Installation** | Soil-cell units are installed beneath the paved surface, filled with uncompacted growing medium, and trees are planted. | **In:** manufactured cell units, growing medium, trees. **Out:** installed green-infrastructure system. | | **Canopy establishment and growth** | The tree establishes and matures within the uncompacted root space provided by the structural system. | **In:** installed system. **Out:** growing tree canopy. | | **Ongoing management service** | Professional urban-forestry services provide long-term tree care, pruning and health monitoring. | **In:** growing canopy, service contract. **Out:** maintained, healthy urban tree stock. | | **Ecosystem-service delivery** | The mature canopy and any biofiltration installations deliver shade, air-quality and biodiversity function to the urban environment. | **In:** maintained tree stock. **Out:** measurable ecosystem-service outcomes. | Cross-cutting technologies of the sector: - **Interlocking structural soil cells:** a load-bearing frame carries pavement traffic loads while the soil volume beneath remains uncompacted and root-hospitable, solving the fundamental conflict between paved infrastructure and healthy tree roots. - **Integrated tree-pit systems:** structural support, root space and stormwater management are combined into a single underground product rather than three separate installations. - **Sensor-driven moss biofiltration:** living moss panels paired with airflow technology target localized air pollution, extending green infrastructure's function beyond canopy shade into active air treatment. --- ## US The US hosts a structural soil-cell hardware specialist alongside a long-established professional urban-forestry service company. ### structural soil-cell hardware, professional urban-forestry services - **DeepRoot Green Infrastructure:** publishes dedicated structural-cell product lines and holds patents on structural cells for facilitating tree root growth, a hardware specialist for urban tree infrastructure. - **Davey Tree Expert Company:** runs a long-term urban soil simulation research program (LTUSS) and continues expanding its residential/commercial operations, positioning long-term urban-forestry research alongside its professional tree-care service business. --- ## CN No China-headquartered green-infrastructure or urban-forestry company cleared this screening round with confirmed, on-domain evidence;
