Convert Heating Systems to Biomass

Lakson awarded via Bio-Énergie Nord Inc. (BEN) with a project to convert heating systems to biomass at the CEN research station (and other commercial buildings to follow) in the greater northern Quebec region. The facility will use innovative technology developed by Lakson to use biomass for fully automated, fully integrated, unattended, and highly efficient heating of the center including process, space, and hot water.

BEN/Lakson plans to design, supply, implement and test its latest residential/institutional heating system using biomass pellets in the far North of Canada prior to full deployment in the regions.

Validation of sizing, performance, components, and pre-selection of the units (including data collection activities obtained by the CEN) will be used to finalize the design, fabrication, and supply of material and equipment.

Conversion of several fossil fuel boilers to biomass firing

Among their redevelopment projects in Canada, Lakson Team is currently mandated by a multinational mining company. “The company produces carbon residues that it wants to recycle, in which there are undesirable components for combustion such as fluorine or chlorine.

With its knowledge of the chemical and mechanical engineering team, Lakson via its affiliate is, therefore, able to propose a process to produce a homogeneous and clean biofuel, thus replacing natural gas in a thermal power plant in Quebec. »

Valorisation of municipal organic sorted Material

Residual materials are a scourge on the entire planet. Our team is currently working on a major project to recover 5,000 tons of organic matter per day in the suburbs of Mexico City.

Following sorting, Lakson’s process lines allow the production of biofertilizer, pyrolytic oil, biochar, biogas and transport pallet molded with wood residues.

Conversion of Residential Heating Systems to the Use of Biomass in Wemindji

At the beginning of 2019, Lakson began studying a project to convert the heating systems of homes (and potentially other residential and commercial buildings) in the far north of Canada, particularly those of the Wemindji municipality in Quebec, to the use of forestry biomass, a product that is widely available in Canada and in the region of Wemindji.

The aim of the project is to replace the existing heating systems that use heavy oil, incidentally eliminating the negative environmental, safety and health impacts that they cause, such as, air pollution and contribution to climate change due to greenhouse gas emissions during the oil’s extraction, transportation and combustion, and the contamination of soil, groundwater and even house foundations, due to oil leaks.

Before launching a full-scale conversion of residential heating systems in Wemindji, Lakson conducted a feasibility study. This study began with a visit to Wemindji, in March 2019, to collect key data necessary to evaluate the project’s feasibility. It also included the visit of different manufacturers of biomass heaters, as well as the preliminary evaluation of biomass resourcing options and the preliminary design of a biomass distribution system, among many activities. The feasibility study, which was completed in April, demonstrated that the project has great potential in terms of environmental benefits, as well as savings for the community.

Residential Homes in Wemindji

The next step for this project, which is to be performed shortly, is the implementation of Lakson’s pilot biomass heater in one of the houses that were visited. For this, Lakson will send a team to Wemindji to install the unit, start it up and train the occupants to use it. This team will compile data during the start-up to incorporate in the final report, which will then be produced to analyze the pilot unit and draw conclusions on its functioning and potential. Furthermore, this will help validate or infirm the conclusions from the feasibility study and it will help formulate recommendations on the potential of fully developing this type of project at a large scale in Wemindji and formulate the next steps to be taken in order to bring this project to fruition.

Development of Solutions for the Valorization of Sargassum Algae in Mexico

Over the past several years, we, at Lakson, have been investigating the problem of sargassum invasion in the Caribbean.

Sargassum, is a type of brown algae that forms in the ocean and that has recently started drifting onto the Caribbean islands, as well as the Mexican Gulf Coast, causing many undesired consequences, some of which are:

  • Pollution of touristic beaches and sites and generation of repulsive smells, which cause a decrease in touristic activity.
  • Can cause eye irritation, respiratory irritation, skin irritation, nausea, vomiting and migraines for the people exposed.
  • Requires costly collection and cleaning operations.
  • Disrupts sea navigation and fishing.
  • Destroys ecosystems; kills fishes and prohibits corals growth.
  • Damages the soil and environment when stockpiled or landfilled.
Invasion of sargassum on Quintana Roo beaches

Through our studies, we have examined and analyzed the different stabilizing and valorization approaches that were proposed by other companies and we have developed our own innovative solution to this problem. Our efforts have led us to a solution that consists in conditioning and valorizing the sargassum as soon as it is brought to shore in order to limit its decay and reduce the emissions of ammonia, methane and hydrogen sulfide, therefore making it more ecological than the more conventional biodigestion approach. Furthermore, our solution generates virtually no residual by-product and is much more compact, easier to maintain and economical than its counterpart.

More recently, in early July, Lakson’s team went to the Quintana Roo region of Mexico to meet various industrials, government officials and scholars/universities, in order to assess the current situation with the algae and propose our solution and services. Our team has been met with positive feedback and we are currently developing the initial phases of several studies and projects together with local partners such as a local university and other key players in Mexico.

Update on our Pilot Project of Treating Maotai Wine Effluent

Last September, Lakson diffused news of a project in development to implement a 10m3/h pilot plant for the treatment of Maotai wine effluent in China. Since then, Lakson has procured and arranged the transportation of the process’ equipment to the site and, in early October, has sent a team to the town of Maotai, China, to erect and start-up the pilot plant.

The installation work was completed without major incident while the start-up activities were punctuated by local inherent site problems, which in the end were fortunately all solved by our on-site team. All criteria pertaining to the quality of the effluent, after its treatment in our pilot plant, was comfortably met.

Our client being satisfied with the result, he has shown interest in a second generation of Lakson’s Maotai wine effluent treatment plant; one that would be automated, more compact and an improvement over its pilot version.

In fact, our client has requested that we develop new larger treatment plants with capacities ranging from 10m3/h to 40m3/h, as well as a mobile and extremely compact plant that could fit in two containers and treat 6m3/h of effluent.

We, at Lakson, are excited about these new diverse projects and are confident that we will successfully complete them; effectively helping Maotai wine producers in treating their effluent in an efficient and economical manner and in reducing their environmental footprint.

Latest Performance Test Results with our BCS 2000 installed in China

Since the recent purchase of our BCS 2000 installed in China from our original client in Wuhan by another industrial in Nanning, our team has been helping the two of them with the implementation of our technology and its adaptation to fit the needs of the new client. Indeed, unlike the original client who used the BCS 2000 to treat municipal waste in the form of sludge to produce fertilizer, the new user of the BCS 2000 desired to treat wood waste, mainly in the form of bark; a change of raw material for which some tuning had to be made to ensure the proper functioning of our system.

After having made the main adjustments, our team, with the help of the new client, conducted performance tests on the BCS 2000 using the new type of raw material. The BCS 2000 was tested with wet bark (at around 60% moisture content) and was able to treat over two Tonnes per hour of this biomass, effectively reducing its moisture content to about 25%. Additionally, the tests demonstrated that the machine was running continuously for the required period of time without defaulting. These results are more than satisfactory as we have reached and maintained the machine’s target capacity. At the client’s request, the system is now being upgraded to achieve even greater performance and reach a capacity up to 50% greater than the actual one.

In parallel, Lakson is currently in the process of developing the BCS 3000, which will have a capacity ranging from three to five Tonnes per hour depending on the condition of the material at the inlet and outlet of our system. With our newest generation of BCS around the corner, we are making the most of our opportunity to optimize the current machine and learn valuable lessons which will be implemented in the design of our newest BCS to make it reach high levels of performance. In this prospect, the latest results obtained with the BCS 2000 are extremely promising and we are extremely excited about our projects in development.
