Summary: The pulp and paper mill biomass boilers in Canada generate large quantities of ash, with most being landfilled and only a small amount being used beneficially. The challenges associated with ash management are expected to worsen over time, highlighting the need to identify beneficial uses for environmental and economic sustainability. Various large-scale and small-scale applications for ash have been identified globally, underscoring the importance of considering the chemical nature of the ashes for specific beneficial applications.

Summary: This paper presents a numerical modeling of acoustophoresis for pulp flow concentration in a pipe. The influences of particle size, mechanical properties, fluid properties, and ultrasound parameters are analyzed within a parametric study to optimize the particle deflection and pulp concentration. The experimental feasibility of industrial use of acoustophoresis for paper pulp concentration is demonstrated with a concentration gain up to 15%.

Summary: This study aims to characterize the ash from the incineration of biomass samples used as fuel in order to understand its influence on the properties of the generated ash fluxes. The results show that the ashes cannot be used as raw materials for clinker production. However, they can be used in concrete and mortar formulations, as a cement substitute or as filler. The maximum incorporation amount depends on the type of biomass used.

Summary: The addition of various amounts of digestate from food waste (DFW)-based compost improved soil properties and promoted the growth of Pak choi. The compost provided essential nutrients such as nitrogen, calcium, magnesium, and organic matter, leading to increased biomass, leaf weight, and root weight of Pak choi. However, excessive nutrient supplementation hindered the growth when the addition amount exceeded 20%.

Summary: This study investigated the effects of catalyst concentration and temperature on product distribution in supercritical water gasification, and demonstrated that group 1A carbonates can increase the yields of H2 and CH4. The results support the development of reaction conditions using effective catalysts to address global bioenergy shortage and effective waste management in the industry.

Summary: China, the top emitter of greenhouse gases, has faced remarkable uncertainty in estimating carbon emissions from its pulp and paper industry. This study re-evaluated the carbon emission using life cycle assessment, applying more accurate emission factors and considering actual energy consumption in factories. The results showed that the national standards for energy consumption in this industry are no longer applicable, and international organizations have overestimated greenhouse gas emissions by approximately 12.00%-56.17%.

Summary: The study found that using black liquor instead of NaOH for the thermo-chemical pretreatment process can increase methane production and reduce treatment costs, making it economically feasible. However, adding black liquor can increase background chemical oxygen demand and volatile fatty acid concentration.

Summary: The application of carbon-rich shungite improved plant ecophysiological traits in onion seedlings under sufficient water supply, but was not very successful in eliminating the negative effects of soil water deficit. The positive effects of shungite were more likely related to nutrient content rather than soil water properties.

Summary: This study provides the first detailed investigation of black agates occurring in the Onega Basin, revealing the different texture types and compositions of these agates. The black color of agates is related to the presence of disseminated carbonaceous matter, with differing metamorphic temperatures identified for different types of black agates. The source of carbonaceous matter in black agates is associated with hydrothermal fluids enriched in CM and incorporated from underlying carbon-bearing rocks.
