Waste & Bio-fuels
Waste and bio-fuels DSEAR risk assessment expertise
We have provided DSEAR risk assessments for waste management, recycling, biomass and bio-fuels operations across the UK.
These environments often involve combustible dusts, mixed waste contaminants, flammable gases and large-scale material handling systems. Our work focuses on identifying where hazardous atmospheres may arise, confirming hazardous area classifications and providing practical recommendations to support safe, compliant operations.

DSEAR risk assessments for waste processing, recycling, biomass and biogas operations
Waste and bio-fuels environments can present complex DSEAR risks because hazardous atmospheres may arise from both the materials being processed and the way those materials are handled, stored or broken down.
Typical risk areas include:
- Waste handling and segregation systems
- Recycling plant and sorting equipment
- Dust from paper, plastic, wood and mixed waste streams
- Biomass storage and transfer operations
- Wood pellet and feedstock handling
- Anaerobic digestion and biogas generation
- Methane transfer, storage and combustion systems
- Ventilation, extraction and dust collection equipment
In recycling and waste processing plants, combustible dust and particulate build-up can create fire and explosion risks, particularly where mixed contaminants are present. Even where the main material appears inert, residual combustible content within waste streams can still lead to hazardous dust deposits or explosive dust clouds under the right conditions.
Biomass and bio-fuels operations introduce additional risks through storage and transfer of organic feedstocks, where dust accumulations and housekeeping become critical. Secondary dust explosions can be especially serious where deposits are allowed to build up around equipment or within enclosed plant.
Anaerobic digestion sites bring a different but equally significant DSEAR risk profile. Methane-rich biogas is routinely generated as part of the process, and without suitable containment, ventilation, testing and maintenance, flammable or explosive atmospheres may occur around tanks, pipework, plant rooms and associated infrastructure.
Our DSEAR assessments review how these hazards arise in real operating conditions, including storage, transfer, housekeeping, ignition control, ventilation, extraction, earthing and equipment maintenance. Where required, hazardous area classification is applied and supported by clear zoning drawings and practical action plans.
The aim is to help operators reduce the likelihood of fire and explosion, improve technical and organisational controls, and maintain compliance with DSEAR across both existing and new facilities.
Common Questions
Yes. Where combustible dusts, flammable waste streams, gases or other dangerous substances are present, DSEAR is likely to apply.
The main risks usually come from combustible dust, mixed waste contaminants, flammable residues, ignition sources and poor housekeeping around plant and storage areas.
Because they routinely generate methane-rich biogas, which is highly flammable and can form explosive atmospheres if released and not properly controlled.
It usually includes review of hazardous substances, plant operations, ventilation, extraction, storage, hazardous area classification and a prioritised action plan for improvements.
