Article
Development of processes for the production of value added products (VAPs), such as biopesticides, microbial inoculants or industrial enzymes through biotransformation of raw or pre-treated wastewater sludge (WWS) has undergone a substantial progress over the last decade. WWS based VAPs are low cost biological alternatives that can compete with che...

Un écoparc d'activités est une zone d'activités économiques particulière dans laquelle les entreprises, industrielles ou tertiaires, souscrivent aux principes du développement durable pour elles-mêmes et la communauté locale. L'écoparc d'activités obéit da...
Article
The cultivation of a microalgae-bacteria consortium in a ternary blend of wastewaters was carried out by varying three variables (organic carbon content in the form of glycerol, CO 2 addition, and light intensity) using a 2 3 full factorial design. An analysis of variance was performed to assess the effects of each factor and their interactions on...

This paper explores the preliminary stages of the design and development of a real project of sustainable regional industrial park. As this project is a public-private partnership between a small business and a county government, both decision makers relied on their respective assets and preferences to develop a project of industrial park with seve...
Article
A 2nd degree mixture design was used to determine the optimal blend prepared from four wastewater streams to produce microalgae-based biomass. The streams consisted of a liquid digestate from an anaerobic digestion process, a landfill leachate, a septic-system sludge treatment plant liquid, and a wastewater treatment plant effluent. The mixture reg...
Article
Adoption of microalgae-sourced products depends on the economic feasibility. In the case of fatty acids, it is crucial to obtain high lipid yield, especially in the form of storage lipids (TAGs). However, the production of these lipids often comes into competition with the microalgae biomass, resulting in a decrease in growth. A microalgae culture...

Abstract Background: Pretreatment of lignocellulosic biomass (LCB) is a key step for its efficient bioconversion into ethanol. Determining the best pretreatment and its parameters requires monitoring its impacts on the biomass material. Here, we used fluorescent protein‑tagged carbohydrate‑binding modules method (FTCM)‑depletion assay to study the...

Article
To produce energy for in-house use, an aluminium smelter in Québec launched a study of mixotrophic cultivation of microalgae in its wastewaters with the objective of having an algae production company set up operations on site. To maximize lipid productivity and maintain the biological integrity of the consortium, specific nutrients need to be adde...

Article
Microalgae are an important source of oils and other molecules that can be used as feedstocks to produce biofuels and high-value products, having the potential of becoming a significant renewable energy source. However, large scale production of microalgal biofuels faces numerous technical challenges, which makes the current growth and development...

From a business perspective, initiatives are undertaken at both inter-company level and intra-company level to implement the concept of sustainable development. At inter-company level, Industrial Ecology uses natural ecosystems as analogies to design sustainable industrial systems such as Eco-Industrial Parks (EIPs). Similarly to a Supply Chain (SC...

Biofuels have the potential to make a significant contribution to greenhouse gas (GHG) reduction goals while creating long-term operating jobs and energy security. However, the appropriate conversion technology for biofuel production is highly dependent upon feedstock availability, feedstock properties, desired fuel properties, availability of supp...

Different types of pulp and paper sludge were used as raw materials for the production of a cocktail of lignocellulolytic enzymes of Trichoderma reesei RUT C-30 (T. reesei RUT C-30). The fungus were grown in pellets to produce cellulases (carbomethylcellulase, β-glucosidase) and hemicellulases (xylanase, β-xylosidase) in three types of sludge: prim...

Considering the diverse compounds contained in lignocellulosic biomasses, especially in agricultural biomass, and the complexity of the different chemical and physical structural connections between these compounds, appropriate analytical methods must be used to characterize these biomasses. In this study, two extraction processes and two analytica...

Techno-economic considerations about forest biorefinery projects in North America with a special focus on the La Tuque project in the province of Québec, Canada.
Article
Along the recent developments of biofuel production, the hydrothermal liquefaction (HTL) of microalgae appears as a major process step which could take advantage of converting the whole microalgae content instead of only extracting its lipid content. This study presents the HTL conversion of a microalgae Chlorella sp. bacteria consortium using a ba...
Article
Pulp and paper mill sludge (PPMS) is an organic residual generated from the wastewater treatments. PPMS management involves economic, environmental and social costs that will likely increase in the future as landfilling tends to be reduced or banned in certain jurisdictions. The reduction or the banning of landfilling may be considered as a climate...
Article
Lignin–melamine–formaldehyde (LMF) resin was prepared by three steps: (i) tosylation of lignin, (ii) synthesis of lignin-melamine (LM) copolymer, and (iii) formation of methylol LM. The synthesized resins were characterized by Fourier transform infrared (FTIR) spectroscopy and phosphorous 31 nuclear magnetic resonance analysis. The curing parameter...
Article
Microalgal biomass represents a sustainable alternative to fossil consumption. Microalgae grow in either photoautotrophic, heterotrophic or mixotrophic modes where the latter two trophic modes require organic carbon to grow efficiently. However, supplementation of organic carbon contributes significantly to a higher cost of microalgae production an...
Article
Fermentation of Bacillus pumilus (B. pumilus) using different pulp and paper sludges as culture media were performed in this work to produce at lower cost industrial enzymes such as xylanases. Secondary sludge was shown to be a suitable alternative culture medium for B. pumilus growth, while primary sludge may serve as xylanases inducer. Mixing pri...
Article
Lyngbya wollei is a benthic filamentous cyanobacterium that produces a toxin analogous to the neurotoxic saxitoxin known as lyngbyatoxin (LYNGTX). Microcystis aeruginosa form blooms in the pelagic area of eutrophic lakes and produce a series of potent hepatotoxins-microcystins (MCYST). The aim of this study in vitro study was to examine the differe...
Article
In this paper, we present a two-step treatment using conventional pulp and paper equipment for agricultural residues to produce a stream of cellulose, a stream of hemicelluloses and a stream of lignin. The role of the different processing parameters (cooking time, temperature, pH, liquor to wood ratio, chemical concentration, etc.) is discussed in...

Plasticizers can persist during the treatment of wastewaters in sewage treatment plants (STPs) and can be discharged in effluents and/or accumulated in sewage sludges. For example, di-2-ethylhexyl phthalate (DEHP) is a common plasticizer that is now considered a priority pollutant and is known to accumulate in sludges. This may add constraints to t...

Bioconversion of wastewater sludge (WWS) has made a substantial progress over last years. Traditional microbial products from WWS such as compost or methane are well studied, but other value added products (VAPs) such as biopesticides, microbial inoculants or industrial enzymes are now proposed. These WWS based VAPs are low cost biological alternat...
