Game-Changing Polymers – Trenchless Article
Trenchless Technology Magazine published an article in their 2021 HDD Guide on the increasing demand for effective liquid waste disposal solutions. In this blog post, we’ll break down the article’s key takeaways.
Can underground infrastructure improvements for transportation be cost-effective and environmentally friendly?
As cities continue to grow and expand, there is an increased need for investment in transportation infrastructure. Transportation infrastructure is not as simple as building new roads and subways, it requires a lot of planning and engineering.
The Demand For Hydro Excavation is Booming
The Hydro Excavation (Hydrovac) market experienced a surge in the last half decade. According to Global Hydrovac Trucks Market’s 2021 research report, the Hydrovac trucks market is expected to continue rising significantly from 2021 to 2026.
MetaFLO’s Reagents Will Help You Comply With Ontario’s New Excess Soil Regulations
All across Canada, municipal and provincial governments have been adjusting regulations pertaining to excess soils. This is largely due to recognition of soil as a valuable commodity. Soil provides habitats for organisms, filters and stores water, supports plant growth, and even more.
Liquid waste is a necessary byproduct of many industrial projects … expensive transportation and disposal doesn’t have to be!
MetaFLO reagents turn liquid waste into a stackable solid in real time while adding only 1/2 of 1% of the liquid waste volume. A proprietary reagent chemistry, MetaFLO reagents replace the need for many common and more costly alternatives like Portland cement, sawdust, lime, fly ash and others giving you an easy, quick and environmentally friendly way to manage your liquid waste streams.
Innovation in Stormwater Pond Maintenance
The ponds you pass every day on your way to work or walking your dog in the evening are not typically spring fed, naturally occurring bodies of water left behind by receding mini glaciers from the last Pleistocene epoch. These ponds have been engineered in housing and commercial areas as a tool to manage water and capture particulate debris from snow melt and rain events.
Innovation in wet tunnel spoils management from MetaFLO
Tunnel construction is underway in every population center around the world and the need is only going to grow as densification and urban migration outpace urban planning, outdated underground infrastructure and capacity.
Vale Waste Sludge Solidification
Vale owns and operates a mining site in Northern Ontario, Canada. Through their mining and refining activities they produce a sludge waste by-product. The clients were in need of an efficient excavation and transportation solution to get this sludge to their off-site landfill.
Ditch Witch partners with Metaflo Technologies, offering Solidification Reagents
Dumping liquid spoils from directional drilling is highly regulated, costly and time consuming. To combat these challenges, Ditch Witch®, a Charles Machine Works Company, has partnered with MetaFLO Technologies to be the exclusive provider of SolidState™ 2 and SolidState™ 6 solidification reagents. This partnership will provide a more accessible and efficient process for the solidification of drilling spoils to an extended network of users and contractors.
Wastewater Lagoon Cleanout
Sewer plants in Carbonne Shire, NSW, Australia have a problem with their waste activated sludge (WAS). This material is typically collected in sludge lagoons designed to collect the sludge as it settles out and release the excess water.
Hydrovac On-Site Solution
Shipping hydrovac mud for disposal out of downtown Toronto reduces productivity and is very costly. These restrictions and costs were a challenge for Crosslinx at the Bayview Station construction site. Not only was Crosslinx able to maximize their productive hours per day with their hydrovac equipment – they only require that single hydrovac to complete daily activities.
Wet or Dry – MetaFLO Solves Excess Soil Challenges
Our solutions for these challenges have diverted millions of cubic metres of soil from landfill to beneficial reuse applications, reduced the carbon footprint of construction work by thousands of tonnes, eliminated the doubt about where excess soils have been deposited and this has all happened while our solutions have reduced the cost of managing these excess soil inventories.
The Business of Dirt
Industry-academic collaborative research projects can be extremely beneficial, especially for small and medium sized enterprises (SMEs), as they can provide access to not only intellectual expertise, but more importantly, access to advanced laboratory equipment and low cost labour (students). There are numerous funding routes that are available for industry-academic collaborations, which allow SMEs to better leverage their resources and get the most bang-for-their-buck.

New Year’s Regulations
It’s going to be an exciting year at MetaFLO Technologies. We have more backlogged projects and are receiving more inquiries from interested organizations than ever before. One common theme from this activity – new regulations, guidelines and enforcement from jurisdictions all over North America.
Pipeline Construction Process Improvement
Pipeline owners are making incremental work process improvements behind the scenes using MetaFLO’s liquid waste solidification technology. MetaFLO provides technology that facilitates the solidification of liquid waste streams into solid material. Organizations that put pipeline in the ground benefit from this proven technology to manage the drill waste fluids and cuttings generated from this work process.
Greenhouse Gas Emissions Reduced by MetaFLO
Major energy projects to factor in greenhouse gas emissionsMetaFLO’s patented solidification technology has already been shown to significantly improve the disposal of waste drilling fluid, by reducing risk, greenhouse gas emissions, and overall cost. At MetaFLO, we believe that there is always a better solution, and we strive to enhance our proven technology to even greater heights.
Municipal Landfills Benefit from MetaFLO Treatment
MetaFLO’s patented solutions are well aligned with the needs of municipal landfills and present a departure from traditional methods of managing slurry waste streams. Heavy liquid waste streams such as hydro excavation mud or horizontal directional drilling (HDD) fluids can be solidified in the field with a very low dose of MetaFLO reagent reducing carbon footprint, waste volume, cost and risk.
How does MetaFLO do it? Sorption.
Seeing our products work for the first time often gets the same response as a street magician does with a surprising card trick. We at MetaFLO are accustomed to seeing liquids turn into solids before our eyes, but many new clients are not. A first time observation of our solidification capabilities usually leads the observer to ask, “How can that be, how does it work?”
Drill Fluid Disposal More Cost-effective Upstream
If you have been following the media recently on the subject of waste soil disposal in Ontario, you will have heard that many ‘clean fill’ dump sites are contaminated with poly-aromatic hydrocarbons, heavy metals and petroleum hydrocarbons. The subject has received comment from Ontario’s Minister of the Environment and Climate Change, Glen Murray, describing the problem as a “serious issue” in Ontario.
