“…The studies analyzed showed that the material or waste from BBA results in a quite different composition of ashes [21][22][23][24]. BBA from waste paper sludge has very high SiO 2 and CaO value and Al2O3 moderate value which is consistent with previous studies by different authors [34].…”

“…In addition, previous studies have verified that the composition of ashes produced at the same thermal plant are notably homogeneous [22], which contrasts with the data provided by Rosales et al [21,23], Beltrán et al [18,19], Cabrera et al [20,24], and Carrasco et al [30]. Therefore, it cannot be said that the ashes generated are homogeneous, as this depends on the plant being analyzed.…”

“…Beltran et al [18,19], Rosales et al [21,23], and Cabrera et al [20,24] used BBA from a thermal plant in Linares, located in Andalusia, in the south of Spain. Biomass composed of 40% dry mass olive cake and 60% dry mass wood biomass (poplar, pine, and olive) were burnt by boiler at a temperature of 403 • C.…”

The chemical composition of BBA varies considerably depending on the combustion temperatures and type of biomass [32], presenting different phases, which influence the density and absorption of the particles, which explains the range of values obtained by different authors.…”

Eco-Efficient Cement-Based Materials Using Biomass Bottom Ash: A Review

In recent years the use of biomass for electricity generation in thermal and cogeneration plants has increased worldwide because it is an environmentally clean fuel whose impact measured in greenhouse gas emissions is practically zero. However, biomass bottom ash, a waste produced during combustion, has also increased considerably, which has both a negative economic and environmental impact, due to landfill transport and management of this by-product. Although biomass bottom ash has potential characteristics for application in the manufacture of construction materials, its full-scale application is difficult because of the wide range in physicochemical properties, depending on the type of biomass burned, such as wood residue, olive waste, waste paper sludge, cocoa shell, etc., and the type of combustion process in the plant. This study reviews the influence on the physicochemical properties, mechanical behavior, and durability of different cement-based materials, such as mortars, concrete, and cement-treated granular material, manufactured from biomass bottom ash. The previous studies demonstrate the feasibility of substituting natural materials for biomass bottom ash in cement-based materials, presenting adequate mechanical behavior and durability properties to comply with the required technical specifications in different building materials.

“…This by-product, unlike the previous one, has not been used as extensively. However, some occasional research has used this residue as a substitute for the fine fraction in mortar and even in concrete [32], obtaining a lower weight of the final material [33] and good mechanical characteristics with its addition [34]. It has also been used as a stabilising element in expansive soils, achieving an improvement in the bearing capacity of the soil after its addition and a drastic reduction in expansion [35].…”

Evaluation of Physical, Chemical, and Environmental Properties of Biomass Bottom Ash for Use as a Filler in Bituminous Mixtures

et al. 2021

The road construction sector is one of the most raw material-intensive sectors in existence. As a result, it has a significant impact on the environment. For this reason, there are several research projects in which industrial by-products are used as raw materials. In turn, energy production from biomass combustion is considered to be one of the most promising energy sources. However, this type of energy produces a number of wastes that need to be treated, such as biomass bottom ash. This research evaluates the properties of biomass bottom ash for use as a filler in bituminous mixtures and quantifies the environmental advantages of its use. For this purpose, the chemical composition of the ashes was analysed and their properties were physically characterised to confirm their suitability as a filler. Subsequently, the advantages of its processing compared to limestone filler, lime, or cement were calculated with SimaPro software. The results showed acceptable properties of biomass bottom ash for use as a filler, as well as a drastic reduction in the environmental impact of its processing. In short, this research presents the basis for the development of further bituminous mixtures with biomass bottom ash, reducing the extraction of raw materials and avoiding landfill disposal.
