MSWI Bottom Ash Utilization in Concrete Mixes

Mokslas - Lietuvos ateitis, 2017
In recent years, along with the global development of the Circular Economy concept and in order to minimise the quantity of waste disposed, waste recovery and reuse of recovered materials as raw materials in various industries while preserving the natural resources is strongly encouraged.

BIOMASS BOTTOM ASH RECYCLING AS PAVEMENT BASE

RURAL DEVELOPMENT 2019, 2020
EU countries agreed upon increasing the use of renewable energy, which strongly stimulates usage of biofuels. Biomass ash is generated as a residue product in large volumes as a result of biomass combustion. Heavy metal content in the ashes is the main hinder for further ash utilization in agriculture, forestry and construction sector.

Fe–Mn Heterojunction Modulated Electronic Environment for Enhanced CO2 Capture and In Situ Conversion

Carbon Energy, EarlyView.
Fe–Mn heterojunctions in CaO‐based dual‐functional materials create a built‐in electric field that drives electron transfer. This process generates oxygen vacancies and facilitates CO2 activation, achieving superior conversion. Waste‐derived Fe/Ca oxides enable low‐cost, thermally stable materials, offering a strategy for sustainable carbon capture and

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...

Analysis of pore structure characteristics of MSWI bottom ash micro powder concrete

Case Studies in Construction Materials
Municipal solid waste incineration (MSWI) bottom ash is a type of bulk waste. Its potential activity can be better harnessed after it is ground into a fine powder, leading to reduced carbon emissions.

Chemical Speciation of Vanadium in Coal Bottom Ash

CLEAN – Soil, Air, Water, 2012
AbstractChemical speciation of vanadium is important to understand the true nature of this element in the environment as well as its biochemical pathways. Sample pretreatment, preparation, and chemical speciation methods were applied for vanadium in coal bottom ash here.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

From Nature to Supply Chain: Exploring Biomimicry‐Based Pathways to Sustainability and Competitive Advantage

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Inspired by insights gleaned from biomimicry theory, this paper addresses the persistent lack of theoretically grounded research in sustainable supply chain management (SSCM) and examines how nature‐inspired biomimicry principles could enhance various dimensions of its competitiveness. This study's theoretical contribution lies in its proposal
