A Field with Specific Challenges

Mastering Risk and Daily Compliance 

Hazardous and residual materials require structured management: inventories, storage, traceability, disposal channels, documentation, and operational practices. Without a clear plan and robust procedures, organizations are exposed to risks (OHS/environment), compliance gaps, and unplanned corrective costs.

Optimizing Channels: Reducing Disposal Costs and Capturing Value 

A portion of industrial waste can be reduced at the source, reused, recovered/recycled, or upcycled. Without a diagnosis and integrated plan, recovery opportunities are lost, disposal volumes increase, and there is a lack of visibility regarding real costs and potential gains.

Projects and Jobsites: Eco-Deconstruction and System Management 

During deconstruction or dismantling, the presence of hazardous materials and the diversity of components complicate planning, segregation, and disposal channels. Furthermore, implementing systems (storage areas, containment cells, etc.) may require proper design and, depending on the case, ministerial permits or authorizations for operation.

Solutions are Possible and Desirable

Integrated Audits and Management Plans (Reduction → Disposal) 

HDS conducts audits for hazardous and residual materials management, then prepares and supports the implementation of integrated plans covering the hierarchy of options: reduction, reuse, recovery/recycling, upcycling, and disposal. Our goal: to structure practices and prioritize high-impact actions.

Management System Design + Permit/Authorization Support 

We design and implement management systems (storage areas, safe landfill/containment cells, etc.) and can assist in preparing ministerial authorization and permit applications related to the operation of these systems, when required.

Industrial Waste Recovery, Eco-Deconstruction, and Training 

HDS provides expertise in the management and recovery of industrial waste and supports eco-deconstruction projects: hazardous and non-hazardous material inventories, estimation of disposal costs, and recoverable amounts through recovery channels (metals, wood, concrete, etc.). We also offer training to ensure the sustainable implementation of best practices.

Achievable Gains

Risk Reduction and Better Compliance Control 

An audit and an integrated plan clarify "what, where, and how to manage": procedures, responsibilities, documentation, and channels. The result: safer management, fewer gaps, and a better ability to demonstrate the organization’s due diligence.

Optimized Costs through Intelligent Channel Management 

By applying the management hierarchy (reduction → recovery → disposal), you decrease the volumes sent for disposal, improve budget predictability, and capture recovery opportunities. Decisions are supported by data and technical/economic analysis when necessary.

Smoother Deconstruction and Implementation Projects 

For eco-deconstruction sites or the setup of storage/containment systems, structured planning reduces unforeseen issues, improves material segregation, and facilitates access to recovery channels. You gain efficiency, traceability, and overall environmental performance.
