Helping you manage post-closure cost

Helping you realize the opportunity

We understand the challenges—and see them as a chance to apply innovative technology.

Are you prepared?

The Landfill Criteria (LC), last updated in 1993, are under review and likely to come into effect in 2015.

The LC will be updated to prescribe state of the art landfill design and management including closure and post-closure. The post-closure care period as defined in the LC as shown below may involve a long-term liability and high financial risk.

“The post closure period for which post-closure care will be determined is the contaminating lifespan of the landfill (e.g. the time period during which leachate collection or landfill gas management or monitoring is necessary). In the absence of technical rational to determine the contaminating lifespan, 1,000 years shall be used as default. In no case shall the post-closure period be less than 30 years.”

Which landfills do the LC apply to?

All landfills in British Columbia (public and private) which receive municipal solid waste, including:

• New landfills

• Lateral and vertical expansions of existing landfills

• New active phases

• Existing landfills

What options are available?

The aerobic stabilization of landfills is a proven technology for reducing the duration of the decomposting process, as well as the GHG and leachate emissions from landfills.


Reducing costs, risks, and mitigating Emissions

We draw on three decades of experience to provide innovative, efficient, and practical solutions for the optimal design and operation of your facility.

What is landfill stabilization?

Research on aerobic stabilization of landfills was conducted by the University of Hamburg on a pilot project in Northern Germany with the following goals:

- To significantly reduce cost for landfill closure and post-closure

- To reduce uncontrolled emissions from landfills

Several projects for landfill stabilization were completed successfully. Aerobic stabilization is integrated into the German landfill regulations as a method to improve the decomposting process and long-term landfill performance.

Two methods for aerobic stabilization were developed:

- Aeroflot-Method (IFAS, Hamburg)

- Depo+ Method (CDM Consult GmbH)

HBHE can help!

Landfill closure and emission control is a very complex topic. Integrating aerobic stabilization into the LFG management design reduces cost.

HBHE provides expertise for:

- Design of landfill gas collection systems

- Integration of aerobic stabilization into LFG design

We offer the following services for these projects:

- Feasibility studies

- Design

- Project Management

- Operational support
