Wastewater
Introduction of foreign industrially produced organic (e.g., fatty acids and protein) and inorganic material (e.g., heavy metals) to water resources has become a global concern. In addition, the municipal waste effluents contain considerable concentrations of drugs and pharmaceutical products as well as detergents and dye pigments. We have generated lignin-based flocculants with superior functionality. Not only these products reduce the load of chemical use for cleaning wastewater effluent (and thus they produce less secondary sludge), but also they are biobased and generally reduce the use of synthetic oil-based products in water resources. In addition, the resultant sludge would contain lignin, which may have potential usage in the production of fertilizers and/ or animal feed mixtures.

Construction
The fluidity of concrete admixtures significantly impacts the workability of the concrete admixture in construction sites, especially in cold climate countries. Water reducers (also known as plasticizers) are extensively used in the construction industry to increase the fluidity of concrete admixtures or reducing the water content of cement pastes. Thanks to the superior properties of our lignin-based products, they have shown promising results in dispersing cement particles and improve cement admixtures’ workability.

Mining and Oil Sands
Mining industry plays an essential role in the overall economy of Canada. Mining processes involved many chemicals in their thickeners, flotation processes, and waste pond management. Although a variety of chemicals is used in this industry, there are primarily oil-based and sometimes inefficient. We have generated altered lignin-based chemicals for different operations of the mining processes. Our preliminary investigation has shown great advantages of these chemicals over the currently used ones in the industry. These chemicals may be used stand-alone or in combination with other chemicals for improved performance.

Pulping Industry
We are producing value-added water-soluble lignin-based products from various industrially produced and lab-made lignin. Our outstanding achievements in valorizing lignin will make it possible to investigate and hopefully replace a whole class of essential commercial petrochemicals with lignin-based alternatives. Our patented technologies can be readily adopted and well-integrated into existing technologies of the pulping industry, which facilitate the commercialization of functional lignin derivatives. The commercialization of lignin-based value-added products will eventually increase the mill’s revenues and will represent a major step towards converting any pulp mills to biorefinery complexes.

Agriculture and Food Packaging
Fertilizers, pesticides, and herbicides are extensively used in agriculture. The gradual and continuous supply of these chemicals is essential for the growth of industrial crops. These chemicals are generally not environmentally friendly or wildlife-friendly. The water supply of crop fields is a major concern worldwide. Interestingly, our lignin-based products can be used in the formulation of these chemicals in industry. The use of lignin-based products can be a strategy to introduce biobased chemicals to the agriculture sector with tremendous environmental and wildlife benefits.

Textiles
The textile industry is one of the most chemically intensive industries on earth. The wastewater generated during various stages of textile processing mainly contains unused dyes that have colors and toxicity. As the driving force for producing effective and environmentally friendly chemicals is high, the need for producing wood-based flocculants for addressing the challenge of this wastewater is high. Our lignin-based cationic and anionic flocculants are targeting dyes with different charge properties and showed successful agglomeration of dye particles. On the other hand, our lignin-based dispersants have shown excellent dispersing properties of various dye solutions.
