Khajeh A, Nazari Z, Movahedrad M, Vakili AH. A state-of-the-art review on the application of lignosulfonate as a green alternative in soil stabilization. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 943:173500. [PMID: 38815820 DOI: 10.1016/j.scitotenv.2024.173500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 05/22/2024] [Accepted: 05/23/2024] [Indexed: 06/01/2024]
Abstract
The utilization of lignosulfonate (LS) as a naturally derived biopolymer sourced from lignin in soil stabilization has gained significant attention in recent years. Its intermolecular interaction, hydrophobic and hydrophilic effects, adhesive and binding properties, erosion control abilities, compatibility with various soil types, and environmental sustainability make it a promising alternative to traditional soil stabilizers as well as highlighting its importance. By integrating LS into soil stabilization practices, soil properties can be enhanced, and an eco-friendlier approach can be adopted in the construction sector. This comprehensive review paper extensively examines the applications and structure of LS, as well as their efficacy and mechanisms on a micro-level scale. Afterward, it discusses the geotechnical characteristics of LS-treated soils, including consistency characteristics, dispersivity properties and erosion behavior, electrical conductivity, compaction parameters, permeability and hydraulic conductivity, compressibility characteristics, swelling potential, strength and stiffness properties, durability, and cyclic loading response. In general, LS incorporation into the soils could enhance the geotechnical properties. For instance, the Unconfined Compressive Strength (UCS) of fine-grained soils was observed to improve up to 105 %, while in the case of granular soils, the improvement can be as high as 450 %. This review also examines the economic and environmental efficiency, as well as challenges and ways forward related to LS stabilization. This can lead to economic and environmental benefits given the abundance of LS as a plant polymer for cleaner production and owing to its carbon neutrality and renewability.

Abstract
The shellfish processing industry is one of the largest growing industries across the globe with a market size of around USD 62B. However, it also leads to a significant environmental issue as it produces >80,000 tons of waste shells globally. Unfortunately, the slow degradation of this waste causes it to accumulate over time, posing a serious threat to the marine environment. The key solution to this problem is to recycle this sea waste into a valuable product like chitin which is further used to produce chitosan. Chitosan is a natural biopolymeric substance obtained via N-deacetylation of the chitin. The chitosan-based nanoparticles are further useful for the fabrication of biopolymeric nanocomposites which are used in various biomedical applications specifically in drug delivery. Here, we review the recent advancements in the development of chitosan-based nanocomposites as a biocompatible carrier for drug delivery, specifically focusing on gene delivery, wound healing, microbial treatment, and anticancer drug delivery. By providing a valuable and up-to-date resource, this review illuminates the current state of research concerning chitosan's pivotal role in the biomedical domain as an efficacious drug delivery agent.

[PMID: 38139878 PMCID: PMC10747516 DOI: 10.3390/polym15244626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 11/30/2023] [Accepted: 12/03/2023] [Indexed: 12/24/2023] Open
Abstract
The conducted investigation encompassed the comprehensive integration of mechanical, environmental, chemical, and microstructural evaluations of a composite amalgamating sandy soil and a synthetic polymer at two distinct concentrations (2.5% and 5%) across multiple curing intervals (0, 1, 2, 4, 7, 15, 30, and 45 days). The studied soil originates from an environmentally significant protected area in Brazil. The implementation of mechanisms for soil improvement in the region must adhere to technical criteria without causing environmental harm. Direct shear testing was conducted, permeability was assessed, and microstructure analysis and XRD and XRF/EDX studies of both the soil and composites were conducted. It was observed that longer curing times yielded improved results in shear stress, friction angle, and cohesive intercept, with SP_5% exhibiting the highest values compared with the soil and SP_2.5%. Adding the polymeric solution to the soil contributed to cementation and cohesion gains in the substrate. Through microstructural characterization, the polymer's role as a cementing agent for the grains is evident, forming a film on the grains and binding them together. Based on the analyses and studies conducted in the research, it can be concluded that there is technical feasibility for applying the polymeric solution at both dosages in geotechnical projects.

Radiation cross-linked ultra-absorbent hydrogel to rationalize irrigation water and fertilizer for maize planting in drought conditions. Int J Biol Macromol 2023; 252:126467. [PMID: 37640186 DOI: 10.1016/j.ijbiomac.2023.126467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/18/2023] [Accepted: 08/21/2023] [Indexed: 08/31/2023]
Abstract
The study addresses the potential negative impacts of climate change on water resources, specifically irrigation water for crops. The radiation technique produces the biomaterial hydrogel as a soil conditioner by polymerizing hydroxy ethyl cellulose/acrylamide (HEC/AAm) at various irradiation doses and copolymer concentrations. A maximum swelling of 23.4 g/g is attained by (HEC/PAAm) hydrogel at 1/7.5 ratio, prepared by 10 kGy gamma irradiation. The study introduces a new class of ultra-absorbent hydrogel (UAH) to address the low swelling limitation for soil conditioner applications. The alkaline hydrolysis treatments with NaOH, LiOH, and KOH enhance the water absorbency of (HEC/PAAm) hydrogel, with the highest capacity of 1220 g/g achieved by the KOH treatment, surpassing NaOH (622 g/g) and LiOH (540 g/g). The cumulative release of fertilizers from the UAH sample shows a slow and controlled release behavior. Urea takes 22 days to reach 100 % release. The UAH demonstrates water retention for 28 days, improving the growth of Zea mays L. at drought stress levels of 0 %, 25 %, 50 %, and 100 %, revealing an increase in shoot length by 16 %, 19 %, 24 %, and 20 %, respectively. Also, UAH increased the contents of chlorophyll a, b, a + b, and carotenoid on maize plant leaves compared to the control sample.
