Introduction. To reduce the stream of solid waste going to landfills, innovative means for beneficial use are essential. The diversity and volume of organic wastes pose singular problems and opportunities for recovery and circularity. Common processes for organics include conversion to biofuels and carbonization to biochar, typically done by torrefaction (dry pyrolysis). Research on biochar explores its potential as pollutant adsorbent, agricultural or polluted soil amendment, biofuel (directly or as feedstock), and for carbon sequestration (Ighalo et al., 2022; Cavali et al., 2023). Recently, other processes at lower temperatures such as hydrothermal carbonization (HTC) offer new possibilities (Seshadri et al., …

One of the global problems is environmental pollution by different biowaste. To solve the problem, biowaste must be recycled. Waste-free technology is also a way of saving exhaustible raw materials. Research on electrochemical energy sources is currently the most dynamically developing area of off-grid energy. Electrochemical capacitors can operate for a long time without changing performance, they have smaller dimensions, high mechanical strength, and a wide operating temperature range. These properties are effective energy-saving devices. Therefore, supercapacitors are widely used in various industries. This review discussed the methods of obtaining and the characteristics of biowaste-derived activated carbon and carbon–manganese oxide …
Effect Of Foliar Spray Application Of Zinc Oxide Nanoparticles On Quantitative, Nutritional, And Physiological Parameters Of Foxtail Millet (Setaria Italica L.)

It has been shown that the foliar application of inorganic nano-materials on cereal plants during their growth cycle enhances the rate of plant productivity by providing a micro-nutrient source. We therefore studied the effects of foliarly applied ZnO nanoparticles (ZnO NPs) on Setaria italica L. foxtail millet’s quantitative, nutritional, and physiological parameters. Scanning electron microscopy showed that the ZnO NPs have an average particle size under 20 nm and dominant spherically shaped morphology. Energy dispersive X-ray spectrometry then confirmed ZnO NP homogeneity, and X-ray diffraction verified their high crystalline and wurtzite-structure symmetry. Although plant height, thousand grain weight, and grain …

Polycyclic aromatic hydrocarbons (PAHs), a family of persistent organic pollutants with various negative health effects, are inherently formed during biochar pyrolysis. However, the knowledge regarding the leaching potentials and mechanisms of PAHs remains limited for biochar implementation to soil. In this study we evaluated the leaching behaviors of PAHs from sewage sludge-derived biochar pyrolyzed at different temperatures (300–700 °C) using the protocol of Synthetic Precipitation Leaching Procedure (SPLP) with deionized water. Leachate concentrations of sixteen U.S. Environmental Protection Agency PAHs increased with the increasing pyrolysis temperature, exhibiting an opposite pyrolytic temperature dependence with their concentrations in biochar. The total leachate …
Elemental Analysis Of Species Specific Wood Ash : A Pyrogenic Factor In Soil Formation And Forest Succession For A Mixed Hardwood Forest Of Northern New Jersey, Michael T. Flood
Elemental Analysis Of Species Specific Wood Ash : A Pyrogenic Factor In Soil Formation And Forest Succession For A Mixed Hardwood Forest Of Northern New Jersey, Michael T. Flood

Fire is a significant environmental perturbation to forests where vegetation transforms from biomass to ash, potentially releasing stored chemical elements to soils. While much research acknowledges variation in ash composition among different vegetation types (grasses, trees, shrubs and vines), less has focused on interspecific variation among trees and the elemental influx soils receive. Therefore, this research sets out to: (1) identify major, trace, and rare earth element (REE) concentrations by inductively coupled plasma mass spectroscopy (ICP-MS) in ash derived from fifteen tree species, (2) determine likely elemental enrichment to post-fire soils, and (3) assess variability in ash chemistry and color …
Water Treatment Residual Coated Wood Mulch For Mitigation Of Toxic Metals And Phosphate From Polluted Urban Stormwater Runoff, Hanieh Soleimanifar
Water Treatment Residual Coated Wood Mulch For Mitigation Of Toxic Metals And Phosphate From Polluted Urban Stormwater Runoff, Hanieh Soleimanifar
Theses, Dissertations and Culminating Projects
Polluted urban runoff as a primary non-point pollution source poses a serious threat to urban human and ecological health. Various urban runoff pollutants challenge the exiting stormwater treatment systems. To support the development of a sound and sustainable urban stormwater management, this dissertation targets at transforming a common landscaping practice, i.e. mulching, into a new stormwater treatment technology through coating aluminum water treatment residual (Al-WTR) on the surface of wood mulch chips. WTR is an industrial waste produced from drinking water treatment plants and primarily comprises amorphous aluminum (hydr)oxides. The Al-WTR coating on the modified wood mulch enables the adsorption …

AMF are symbionts to a majority of terrestrial plants and can improve plant nutrient uptake, water relations, and stress tolerance. This study evaluated the effects of AMF in heavy metal contaminated soils via a growth chamber experiment to determine the interactions between soil and arbuscular mycorrhizal fungi (AMF) affecting plant growth. Rye grass was grown in two contaminated soils from Liberty State Park, an urban brownfield, and one non-contaminated commercial soil, to which half of the treatments received AMF inoculum. Dried plant biomass, root:shoot ratio, and soil phosphatase activity were measured at the completion of the experiment. Soil contamination was …
