Robust Emission & Odour Control for the Recycling Industry

Q: What emissions are typical in recycling plants?

Odorous organics, H2S/NH3 from organics handling, acid gases and mists from leach/neutralisation steps, and moist particulate-laden exhaust from washing and drying lines.

Q: How do you handle solids and abrasion?

We use wear-aware layouts with pre-separation, cleanable internals and access doors; materials are selected for chemistry and abrasion. Drains and demisters limit re-entrainment.

Recycling facilities handle mixed and variable streams that can release odorous organics, acid/base gases, aerosols and abrasive particulates. Ravebo designs and builds tailored wet scrubber systems that protect people and assets, reduce nuisance and keep operations compliant.

Why emission & odour control matters in recycling

Mixed waste streams, intermittent peaks and harsh chemistries demand predictable, low-maintenance abatement. The right system protects workers and neighbours, prevents corrosion and secures permits.

Compliance & permits
Meet emission limits and reduce odour complaints.
Worker & community safety
Capture toxic and odorous compounds before release.
Asset protection
Limit corrosion and sticky deposits on ducts and stacks.
Operational continuity
Stable performance with predictable OPEX.

Key challenges in Recycling

From sulphur odours to acid fumes and moist, particulate-laden exhaust—recycling sites need robust capture and separation across changing loads.

Top challenges

Odorous organics
Amines/aldehydes/ketones from washing, shredding and drying lines.
H₂S & NH₃
Organics/AD and certain waste streams generate nuisance gases.
Acid fumes from hydromet
HCl/H₂SO₄ mists and fumes during leaching/neutralisation.
Aerosols, steam & solids
Moist exhaust with fibres/dust needs reliable separation and drainage.

Recycling process lines and exhaust capture

Ravebo solutions for the Recycling Industry

We configure wet scrubbers per application—matching absorption chemistry, droplet separation, materials and controls for compliant, low-maintenance performance.

Packed-bed absorption

High-efficiency gas absorption for acid/base gases (HCl, H₂SO₄ mist, NH₃) with the right liquor and residence time.

Mist elimination & polishing

High-efficiency droplet separation and optional polishing (e.g., carbon) to minimise residual odour/VOCs.

Materials & abrasion control

PP, PE, PVC-C, FRP or stainless; wear-aware layouts, cleanable internals and access for inspection.

Water & effluent management

Optimised recirculation with monitored blowdown (pH/ORP/conductivity), neutralisation/oxidation and solids handling.

Case Study

Acid-gas abatement at battery-recycling hydromet line

A recycling plant experienced corrosive fumes and odour around hydrometallurgical stations. Ravebo supplied a compact multi-stage scrubber with packed-bed absorption, high-efficiency mist elimination and integrated blowdown handling.

Recycling FAQ

What emissions are typical in recycling plants?

Odorous organics, H₂S/NH₃ from organics handling, acid gases and mists from leach/neutralisation steps, and moist particulate-laden exhaust from washing and drying lines.

How do you handle solids and abrasion?

Wear-aware layouts with pre-separation, cleanable internals and access doors; materials selected for chemistry and abrasion. We design drains and demisters to limit re-entrainment.

How is water and effluent managed?

Recirculation with monitored blowdown (pH/ORP/conductivity), neutralisation/oxidation and solids handling, aligned with site permits and wastewater limits.
