Biosolids & Other Organics

The Problem

Whether it is biosolids, abattoir waste, animal manures, contaminated or mixed organics or any other biomass waste source, there are a number of pressing challenges that we at, IQ Energy, can assist you with for your project.

Challenges you may be facing that we can discuss:

The IQ Energy Solution

IQ Energy Gasification Unit

IQ Energy Inc. is having a number of conversations discussing various organic waste streams. One of the main feedstocks of discussion is biosolids (sewage sludge). Generally, a feedstock, like biosolids, has a higher moisture content and will need either a dryer-only solution or a dryer and gasification solution. When it is an indirect dryer and gasification solution most of the energy value of the dewatered sludge will be needed to produce heat to do the drying which creates an effective renewable drying loop with a valuable biochar or char/ash produced.

IQ Energy can provide a cost-effective, scalable and readily available solution. IQ Energy Units can work either as a centralised plant design or through a decentralised model and are movable to ensure they do not become stranded assets for a business. The compact design of the units allows them to fit neatly into a current plant.

At the heart of the IQ Energy solution is sophisticated software programming to ensure continuous operating units that can be monitored and operated remotely. This programming has been developed alongside the decades of organic feedstock handling within thermal treatment equipment.

Autothermal Continuous Solution

Circular: Dried Product to the Gasifier & Heat Back to the Dryer

Increasingly biochar has been gaining attention for its environmental and agricultural benefits. Whether biochar or char/ash is produced within an IQ Energy system is dependent on how much carbon needs to be reacted through the thermal treatment process. Both a biochar or a char/ash will have value within an agricultural or industrial outcome. Some key advantages of these products are:

  • Soil Improvement

  • Nutrient Qualities and Agricultural Yield Improvement

  • Carbon Sequestration

  • Cost Reduction/Revenue Opportunity

  • Potential Carbon Credits

  • Cementitious Qualities for Industry and Infrastructure

With this IQ Energy will be conducting plot trials to understand further benefits of the biochar produced from the IQ Energy unit that will be operating in Alberta.

Uses & Benefits of Biochar or a Char/Ash

Benefits of the IQ Energy Approach:

Biosolids & Other Organics

Risk Management

  • Modular units to help scale to the solution on a pre-existing site and address front of mind social licence concerns, like land availability, odour, and processing time.

  • Repeatable manufactured units with repetable safe, trusted and clean outcomes helping to build trust by regulators and the community.

  • Manufactured and delivered onsite within 10-12 months to quickly address current challenges at a locked in price.

Financial Management

  • Fixed Costs Savings: Reducing the tonnages of feedstock to offset rising trucking/disposal costs and offsetting potential onsite energy needs, through heat, gas or power generation.

  • New Revenue Opportunities: Value to be placed on creating a dried product or a biochar or char/ash for agriculture or industry, from recovering water, and for potential carbon credits.

Pressing Concerns Management

  • Emerging Contaminants: Built into the IQ Energy Gasification Unit is an extended retention chamber, to achieve higher temperature and residence times which can help you address issues, such as PFAS and microplastics.

  • Emission Pressures: IQ Energy Units can have a signficant posive impact on greenhouse gases by:

    • Displacing fossil fuel usage for drying or offsetting onsite energy needs.

    • Reducing trucking and stockpiling needs.

    • Intercepting emissions, such as methane and nitrous oxide, to help with scope 1 and 2 emissions and stopping emissions produced by landfills.

    • Sequestering carbon as a char.

Sizing IQ Energy Units for Your Project

G300 Gasification Unit

Approximate Input: ~2,300 dry tonnes per annum

G500 Gasification Unit

Approximate Input: ~3,800 dry tonnes per annum

G1000 Gasification Unit

Approximate Input: ~7,700 dry tonnes per annum

IDT1000 Indirect Dryer Unit

Approximate Input: ~8,000 wet tonnes per annum

IDT5000 Indirect Dryer Unit

Approximate Input: ~40,000 wet tonnes per annum

The above units can be configured together for your project needs. For example our G1000 gasification unit fits neatly with our IDT5000 Indirect Dryer Unit. However we can also match our gasification unit with other dryer units currently on the market that you may prefer to use. In addition our pyrolysis unit can be used with biomass wastes to produce a gas output. We only recommend out pyrolysis unit when biomass feedstocks are already dry as our gasification unit provides more efficient heat for drying wet wastes.

Scaling IQ Energy Units Up for Larger Projects

Above is 5 gasification units with 3 dryers which are simply fitted together for continuous processing and redundancy options. This configuration can process ~90,000 tonnes of dewatered biosolids per annum.

A modular unit approach can be of interest to a number of project operators for various reasons. It provides the opportunity to scale up over time, to scale quickly to meet urgent challenges, to trial an opportunity without over committing to a full project build and various other reasons. As biomass waste streams can grow overtime with factors, such as population increase, this means strategic planning is difficult as traditional plant build designs provide challenges with over capacity, long build times, significant engineering costs and high capital and operational costs. A modular approach allows you to bring in further units as needed and scale to your waste source as it grows and/or provide redundancy options.
