Engineering & Environmental Technologies for Industry
We design and develop advanced engineered systems for the management and treatment of emissions from industrial processes, integrating capture, air conveying, filtration, abatement and control.
About us
Tailored systems, from process to commissioning
Every project starts from an analysis of the production process and its operating conditions, to develop tailored systems that combine performance, energy efficiency, reliability and regulatory compliance.
From feasibility study to engineering, from construction to commissioning, ENVIGREEN manages the entire development of the plant, integrating technologies and components to meet the specific needs of each process.
Solutions
The right technology for each pollutant
We choose the technology from what the process emits: pollutant type, concentration, temperature, humidity and explosion risk.
Dust collection
Bag and cartridge filters, cyclones and separators, with reverse-pulse cleaning and dust discharge.
Dust · particulateWet scrubbers
Packed towers and venturi scrubbers for acid and alkaline gases, with recirculation, reagent dosing and pH control.
HCl · NOx · NH₃ · SOxWelding fumes and oil mist
Mechanical and electrostatic filtration for machining, welding and machine tools.
Fumes · mist · aerosolsVOCs and odours
Activated carbon adsorption and combined systems for solvents and odorous emissions.
VOC · solvents · odoursBiofiltration
Organic-bed biofilters in which microbial flora degrades odours and biodegradable compounds, with air humidification and filter media management.
Odours · H₂S · NH₃ · biodegradable VOCsExplosive atmospheres (ATEX)
Systems for combustible dusts and vapours, with components compliant with Directive 2014/34/EU: vents, isolation valves, earthing.

Every project starts from data
We agree the design parameters with the client and verify them at commissioning. These are the values that matter for performance and for the emission permit.

How we work
From site survey to commissioning, one point of contact
A system performs well when it is designed around the real process. That is why we start on the shop floor, not from a catalogue.
Site survey and analysis
We map emission points, processes, available space and operating constraints.
Engineering
We size airflows, ducts and pressure drops, select filters and fans, and produce P&IDs and layouts.
Permitting support
We prepare the technical documentation on air emissions required for permits.
Supply and installation
We coordinate fabrication, erection, electrical panels and start-up.
Testing and measurements
We check airflows, capture velocities and pressures against design values.
Maintenance and service
Maintenance plans, spare parts and service calls to keep the system efficient over time.
