12MW Biomass to Energy Plant

Lakson International Development Inc. is proud to conclude, in February 2020, a mandate for performing the basic engineering for a 12-megawatt biomass power plant to be located in Martinique.

Lakson introduces its innovative technology for conditioning and transforming of several types of biomass whereby they are reduced to a fine dry powder that feeds its suspension firing burners equip high pressure steam boiler systems, generating superheated steam that drives a turbo-generator producing electricity.

The biomass grown locally in Martinique, once harvested and conditioned, feed the power plant the year longue.  Conditioned biomass delivered directly on site reduces greatly the cost of transportation, storage and logistics while promoting labour and the local circular economy, replacing oil and reducing greenhouse gases.

In the next steps, Lakson and associates will assist in financial structuring, detailed engineering, and the supply of equipment, construction (EPCM) and other services enabling the client to carry out the project as rapidly, reliably, economically environment friendly as possible.

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.

Supply of a Pilot Plant for the Treatment of Effluents from the Spirits Industry

Over the past several months, we, at Lakson International Development, along with our partners, have been working on developing our own process and intellectual property for the treatment of wastewater effluents from the spirits industry. This project started when our client, an important actor of this industry in China, approached us after several failed attempts at treating and recuperating its effluents.

This led us to dedicate a team almost entirely to the development of an innovative solution, which in turn led to the proposal of our services in the form of a 10m3/hr pilot plant that would treat and purify these effluents so that they could be recycled. At this point in the project, our team has completed the design for this pilot plant, we have completed the procurement of the process’ main equipment and the project is in its execution phase.

Update on our project of municipal sludge treatment near Wuhan, China

It has now been more than a year since we have installed our 2nd generation patented Biomass Conditioning System (BCS 2000) for our client’s municipal sludge treatment plant near Wuhan in China. We are proud to announce that after several months of optimization, our system can now meet and even exceed its targeted throughput capacity for municipal sludge treatment. The resulting product is a fine and dry powder that is pelletized or used in its intermediary form as a bio-solid/organic fertilizer depending on raw material composition and final product requirements.

With this success, new opportunities have now been opened to us in China, and elsewhere, as we are developing new projects for the treatment of municipal sludge, industrial sludge, wood waste and municipal solid waste via processes that include our new emerging Biomass Conditioning Systems: the BCS 3000, the latest generation of BCS that can treat biomass at much higher capacities; and the BCS M500, our mobile treatment unit which can fit in a standard 40-feet container for a convenient periodic treatment operation of different sites and plants.

Projects in development in different communities of Ivory Coast

In the past months, Lakson International Development took part in numerous meetings held in Ivory Coast, with the Secrétariat National au Renforcement des Capacités (National Secretary for Capacity Building). The purpose of these meetings was to discuss eight pilot projects of data collection and analyses that were conducted to evaluate the capacity of eight communities and make recommendations.

In this context, Lakson proposed several development projects aimed at reinforcing the economical and social emergence of these communities by the year 2020.

The projects in question concern the agri-food sector and consist in adding value to a variety of raw agricultural products such as the cassava root, the cocoa bean, the coconut, the cashew nut and the palm fruit, by processing them and producing by-products. Along with these projects, a project of aquaponic systems is in development.

All eight communities are targeted by Lakson‘s projects.
