Odour and dust control
Odour and dust are the two complaints that close fertilizer plants. Both are engineering problems with known solutions: contain the source, extract a

Permitting checklist
| Item | What the authority usually asks | What the plant design provides |
|---|---|---|
| Land use | Is the site zoned for this use? Setbacks satisfied? | Plot plan with distances and neighbouring land uses |
| Odour | Sources, containment and treatment | Enclosure, extraction volumes, biofilter or scrubber specification |
| Dust | Capture points and filtration | Extraction and filtration schedule per process step |
| Noise | Equipment noise levels and operating hours | Equipment noise data and the proposed operating schedule |
| Water and run-off | Where does contaminated water go? | Drainage plan separating clean water from leachate; containment and reuse |
| Waste handling | Types and quantities of material received | Mass balance and reception records |
| Traffic | Vehicle numbers and access | Site circulation plan and dispatch schedule |
| Product | Declared analysis and labelling | Product specification and quality-control plan |

The evidence trail
- Reception records: material type, tonnage, source and moisture.
- Process records: fermentation temperature and residence time per batch or bay.
- Product records: moisture, size distribution, granule strength, bag weights, and analysis results from an accredited laboratory where required.
- Environmental records: extraction operating hours, biofilter maintenance, leachate volumes and destination.
- Complaint log with the investigation and outcome — a documented response is worth more than an absence of complaints.

Where our responsibility ends
An engineering scope, not legal advice
We provide the technical content an application needs — layout, process description, emission points, extraction and treatment design, mass balance and process records — and we design the plant so that it can meet the limits the customer is required to hold.
We do not give legal or regulatory advice, we do not apply for permits on the customer's behalf, and we cannot guarantee that an authority will grant a permit. That is why the permitting checklist is part of the design stage: the answers shape the layout and the equipment, and finding them out early is what prevents a plant that cannot be operated as built.
Get the technical annex for your application
Tell us the authority's requirements and the site; we return the layout, process and emission information needed for the application.
FAQ
Plant engineering questions
Do I need an environmental permit for a composting plant?
Most jurisdictions require some form of authorisation above a threshold tonnage, and on-farm composting of a farm's own material is often treated differently from importing waste. Confirm the position with the local authority before design, because it changes the containment and treatment scope.
What causes most permit refusals?
Inadequate odour management, uncontrolled run-off, and insufficient distance to sensitive receptors. All three are visible in the design stage and are cheaper to solve in the layout than in an appeal.
What product documentation is needed?
The declared nutrient content, organic matter, moisture, particle size, and the heavy-metal and pathogen results your market requires. These come from the production quality-control plan supported by periodic accredited laboratory analysis.
Does the plant need to record every batch?
For a commercial operation, yes — batch records are what allow a product complaint to be traced and are often a condition of supply contracts and of certification schemes.
Send us your design basis
Tell us the feedstock, the daily tonnage and the product you want to sell. The engineering team replies with the plant configuration, the equipment scope and the information we still need before layout drawings start.
- Feedstock profile — type, moisture, contamination, seasonal peaks
- Capacity — t/day fresh material or t/h finished fertilizer
- Product — powder, granules, bagged retail, bulk compost
- Site — available area, power supply, water, access road
