The Relationship between Socio-economic Characteristics of Urban Inhabitants and the Quantity of Domestic Waste Generation in Mattakkuliya Grama Niladhari Division, Colombo

The unwanted objects and unusable substances are referred as waste. These are classified as agricultural waste (AW), commercial waste (CW), domestic waste (DW), and industrial waste (IW) based on their source of generation. DW is generated during the household activities like cleaning, cooking, etc. The exodus of DW is comparatively very high in urban areas than in rural. Also, there is a close relationship between the quantity of DW and the socio-economic characterizes of urban inhabitants. The objectives of this study are identifying the generating factors of DW and to explore the relationship between socio-economic characteristics of urban inhabitants and the quantity of domestic waste. To achieve the objective of the study, 150 houses in Mattakkuliya were randomly selected. Providing questionnaire, unstructured interview, and observation were the primary data collection method. Secondary data such as research papers, statistical reports, and the Internet were used for further data. Based on the study, about 3.5-16 kg of DW is produced daily from each household in the study area. Meanwhile, the daily per capita waste production is found to be 0.5-5 kg. Of these, food scraps (45%), paper (20%), glass (5%), plastic bags (18%) and others (12%) were the most important. Results indicated a linear relationship between socio-economic characteristics and the quantity of DW in the study area. Thus, direct and indirect socio-economic characteristics such as family size, income, average age of the family members, sex, occupation, literacy and marital status were the explored by the study.

Commercial‐scale remediation of per‐ and polyfluoroalkyl substances from a landfill leachate catchment using Surface‐Active Foam Fractionation (SAFF®)

AbstractThis article presents the results from a commercial‐scale field trial of the Surface‐Active Foam Fractionation (SAFF) process for the removal of per‐ and polyfluoroalkyl substances (PFAS) from a landfill leachate catchment at the Telge Recycling plant, Sweden. There have been 23 sampling events for PFAS influent and effluent concentrations over the course of 10 months, during which approximately 80,000 m3 of leachate feed has been successfully treated without the need for complex pretreatment. The contracted throughput was 330 m3 per day (120,000 m3/year), but, in practice, it varied between 200 m3 and 500 m3 per day depending upon the inventory of the upstream leachate catchment. Over the trial period, it was demonstrated that SAFF was successful in removing ≥98.7% perfluorooctane sulfonate (PFOS), ≥99.7% perfluorooctanoic acid (PFOA), and ≥98.8% perfluorohexane sulfonate (PFHxS) from the feed stream without using absorbent media or chemical amendment consumables, including the partial/significant removal of other PFAS species. The reported removal percentages are constrained by the limit of reporting (LOR) of analytical testing of the “treated stream”; the actual removal percentages could be higher as detailed by a single sampling event “I” included herein. The mean concentrations of the treated stream were ≤2.34 ng/L PFOS, ≤1.28 ng/L PFOA, and ≤1.00 ng/L PFHxS; the contractual criteria requirement was to reduce PFOS to <50 ng/L. The results are concordant with those obtained by Burns et al. (2021) who demonstrated that SAFF technology removed ≥99.8% PFOS, ≥99.8% PFOA, and ≥98.4% PFHxS from a PFAS‐contaminated groundwater stream at the Army Aviation Centre Oakey military base in Australia. The present study extends what was learned from the previous Australian groundwater study in that there is more complex chemistry associated with the leachate feed stream arising from landfill receipt of domestic, commercial, and industrial waste to the landfill cells. In addition, the climatic dependency that was considered by Burns et al. (2021) is explored in a colder environment and is found to be practically insignificant with respect to PFAS removal. Burns et al. (2021) asserted that nearly complete PFAS removal is achieved if the Brusseau adsorption coefficient is greater than approximately 1 µm. The present study extends this analysis to demonstrate that removal percentages fall to approximately 0 at an adsorption coefficient of 0.02 µm with a functional form of a sigmoid on semi‐log axes.

Nano-calcium Powder Properties from Six Commercial Fish Bone Waste in Indonesia

Low daily calcium intake in Asia, especially in Indonesia, is still a serious problem. The abundant fish bone waste from the fishery fillet industries in Indonesia, can be employed as an alternative source of calcium to meet daily calcium needs. This research aimed to determine which of the six fish species (tilapia, catfish, grouper, snapper, tuna, kingfish mackerel) produces the best quality and the most cost-effective nano-calcium powder for a recommendation to the stakeholders. The calcium was extracted using an alkali treatment. The properties of the produced nano-calcium powders were analyzed for: proximate composition, calcium and phosphorus levels, color brightness level, XRD, FTIR, particle size, and SEM-EDX image analysis. The tilapia bone had the finest particle size of calcium (87.37 nm), while the grouper bone had the biggest particle size (281.4 nm). The brightness of all yields varied from 83.83 (beige-kingfish mackerel) to 90.64 (white-tilapia). The average calcium content from EDX analysis varied from 21.51% (snapper) to 34.37% (grouper). The average phosphorus levels ranged from 10.73% (kingfish mackerel) to 15.99% (grouper). The EDX Ca/P molar ratio was 1.41-1.66 across all samples. The FTIR spectra showed that all samples contained PO, CH, CO, NH, and OH groups. The XRD spectra pattern determined that the two main components of the fish bone nano-calcium powder were 90% hydroxyapatite and halite. All fish bone samples have the potential to be used as raw material for nano-sized calcium. However, grouper bone with the highest calcium content and the highest nano-calcium yield was the best choice for further study.

Sanitation and waste management practices and possible implications on groundwater quality in peri‑urban areas, Doba and Nayagenia, northeastern Ghana

Access to potable water, proper sanitation, and hygiene have become global concerns. The study assessed sanitation and waste management practices and the possible implications on groundwater quality in Doba and Nayagnia. The data were elicited from 240 households using a semi-structured questionnaire. Besides, 10 composite groundwater (boreholes and well) samples were collected for total coliform and E. coli analyses. The data was analyzed using cross-tabulation and descriptive statistical tools using the R software. The study showed that there was a strong relationship (P < 0.001) between the respondents' perceptions of the importance of sanitation and their levels of education. Also, there was a significant relationship (P < 0.001) between the availability of household toilets and income levels. The availability of household waste receptacles was statistically significant with income levels (P = 0.006) and subscriptions for commercial waste collection (P = 0.009). Open defecation was influenced by inconveniently sited (P = 0.004) and poorly maintained public toilets (P = 0.009). About 73% of the households relied on boreholes as their major source of water. However, all the groundwater sources contained loads of enteric bacteria. The results of the Friedman test were significant based on an alpha value of 0.05, χ2 (2) = 8.86, p = 0.012 for total coliform and χ2 (2) = 7.80, p = 0.020 for E. coli. Generally, the communities practiced unimproved sanitation practices which may pose potential effects on public health. Alongside environmental health education, the provision of toilets and waste collection receptacles will address the environmental challenges discussed in this study .

Waste Characterization Study of Pre-Covid-19 Commercial Office Buildings

This study examines the average commercial office waste profile by region and by program type. The regions included in this study, including New York, the Mid Atlantic, California and others, had different recycling/composting program mandates. Within regions, building waste diversion programs differed as well. The results of the review reflect some differences in the success of the diversion programs utilized: single stream recycling, multi stream recycling and with or without organics programs. Over 100 waste audit results were compiled representing commercial office waste prior to the changes in the commercial real estate and waste industries during the COVID 19 pandemic.

Lactic acid production from food waste using a microbial consortium: Focus on key parameters for process upscaling and fermentation residues valorization

In this study, the production of lactic acid from food waste in industrially relevant conditions was investigated. Laboratory assays were first performed in batch conditions to determine the suitable operational parameters for an efficient lactic acid production. The use of compost as inoculum, the regulation of temperature at 35 °C and pH at 5 enhanced the development of Lactobacillus sp. resulting in the production of 70 g/L of lactic acid with a selectivity of 89% over the other carboxylic acids. Those parameters were then applied at pilot scale in successive fed-batch fermentations. The subsequent high concentration (68 g/L), yield (0.38 g/gTS) and selectivity (77%) in lactic acid demonstrated the applicability of the process. To integrate the process into a complete value chain, fermentation residues were then converted into biogas through anaerobic digestion. Lastly, the experiment was successfully replicated using commercial and municipal waste collected in France.

Promoting Tunisian agri-food start-up. A study on the self-efficacy of aspiring entrepreneurs

In 2011, Tunisia went through a revolution which transformed its modern history. Currently, the country is experiencing a moment of transition in which it faces problems, both on a social and economic level. The region Kroumerie-Mogods, in the northwest, includes the three Governorates of Jendouba, Beja and Bizerte, is strongly affected by past economic policies. Despite having great potential in terms of both natural resources and economic opportunities, the local population appears to be among the poorest in the country, suffering from high level of unemployment, widespread poverty and substantial inequalities. In this context, a Development Cooperation project was implemented with the aim of creating new employment opportunities, especially for young people and women, through the enhancement of the territory and its agricultural products with the support of new entrepreneurial initiatives. Principal Component Analysis and Logit model were used to analyse the Self-Efficacy (SE) of young aspiring entrepreneurs and to evaluate its effects on the promotion of personal entrepreneurial projects. The study shows that past involvement in business key activities, as commercial experiences, social commitments and sustainable waste management, represent a decisive element for the promotion of personal business projects in agri-food sector.

STUDY OF HAZARDOUS WASTE TREATMENT AND MANAGEMENT FOR THE OIL AND GAS INDUSTRIES

Study of hazardous waste treatment and management for the oil and gas industries has been conducted by Lemigas Team to observe the existing guidelines and the implementation of the guidelines in hazardous waste management. The study also includes a selection of the government regulation that should be considered in the hazardous waste treatment and management for the oil and gas industries. Results of the study indicate that the oil industry does not conduct treatment processes for all hazardous wastes that are generated. Some of them, especially those of non-specific hazardous wastes are stored in a temporary storage facility and managed off site for treatment or disposal to a commercial hazardous waste facility. The off-site waste management requires the use of a document termed a manifest for tracking its transport on a "cradle-to-grave" basis. The most prominent problem faced by the oil production industries, however, is the vast generation of wastes from production operation activities such as drilling mud, oil contaminated soil, and oil tank sludge and pit sludge. All of these wastes need to be handled properly. This paper presents the results of the study describing the existing guidelines used by the oil and gas industry and its implementation as well as reviewing the government regulation related to hazardous waste management and the technologies that can be applied in mitigating the hazardous wastes generated by the oil and gas industries.

Performance Monitoring of Anaerobic Digestion at Various Organic Loading Rates of Commercial Malaysian Food Waste.

Application of anaerobic digestion (AD) has become common in treating palm oil mill effluent in Malaysia; however, employing AD in treating the organic fraction of municipal solid waste (OFMSW), especially food waste, is still scarce. This study aims to characterize the commercial Malaysian food waste (CMFW) and determine its potential as sustainable bioenergy feedstock through biogas production. The sample was digested via the biomethane potential (BMP) test with the variation of organic loading rates (OLRs), ranging from 0.38 to 3.83 gCOD/L. day, under mesophilic conditions. The digestion process was further evaluated in continuous operation using a 6-L continuous stirred-tank reactor (CSTR). The kinetic properties of the process were also determined. It was found that the CMFW had a significant amount of chemical oxygen demand of 230 g/L and an acidic pH of 4.5 with the carbon to nitrogen (C/N) ratio at 121:1. A maximum methane composition of 81% was obtained at 1.92 gCOD/L in the BMP test with specific methane production (SMP) at 0.952 L. CH4/L.COD fed. The biogas production was well-fitted with the modified Gompertz model with R 2 at 0.9983 and the maximum biogas potential production rate at Rm 0.1573 L/day, whereas in the CSTR operation, a maximum methane composition of 85% was produced at OLR 6 gCOD/L. day with the SMP of 1.13 L. CH4/L.COD fed. The CSTR system was in high stability as the pH was maintained in a range of 6.6–6.7, with an alkalinity ratio of 0.28. This study indicates the CMFW is a sustainable feedstock for biogas production in Malaysia. Toward a circular economy approach, the authorities shall introduce commercial scale CMFW AD as part of managing municipal solid waste issues in Malaysia.

The research also dealt with the study of municipal solid waste, the rate of waste generation, and the factors affecting it. It referred to the physical and chemical composition of solid waste, the arrangement of waste management and its objectives, and the most important stages of waste flow. It discussed the methods of waste collection, sorting, and recycling, the most important human characteristics, and the natural factors affecting them, concerning the negative effects of waste on the environment.

Evaluating Barriers, Enablers and Opportunities for Closing the Loop through ‘Waste Upcycling’: A Systematic Literature Review

The United Nations Sustainable Development Goals aim to ‘do more and better with less’, with numerous calls to action arising from the business sector concerning the substantial reduction of targeted types of commercial and industrial waste. Emanating from the original work on closing material loops by McDonough and Braungardt in the 1990s, over the last two decades the concept of ‘upcycling’ has increased in popularity as a targeted intervention to reduce material and energy use in business processes. Essentially upcycling involves reusing, repairing, repurposing and upgrading waste material to avoid the conventional endpoint of ‘disposal’. However, upcycling is still considered a niche practice and many business enterprises remain unclear as to how to use upcycling opportunities for better management of their waste. In this paper, the authors propose a Tiered Approach to Waste Upcycling for Business, as a strategic way for businesses to close the loop within their industrial processes and production chains. The paper comprises a systematic literature review of opportunities and barriers for enabling business enterprises to close the loop through waste upcycling. The review highlights the ad hoc, champion-based and highly variable use of upcycling practices and uncovers opportunities for more systematic and streamlined practices to produce value-added products from waste material. Synthesising the findings, the authors establish three tiers of ‘macro’, ‘meso’ and ‘micro’ barriers and enablers that businesses can consider identifying upcycling opportunities for managing their waste. The authors also discuss key benefits of upcycling including improved quality and life of material, creating jobs and influencing positive consumer behaviour. The authors conclude the benefits of a structured approach to considering circular economy opportunities, towards improved waste management that is better for the bottom line, people and planet. With regard to future research in the field, the authors define a set of key theoretical constructs relating to waste upcycling, that can facilitate innovation and investigations into applying ideas.

Managing food waste is key to tackling climate change

Managing food waste is key to tackling climate change

How does COVID-19 affect the life cycle environmental impacts of U.S. household energy and food consumption?

The COVID-19 pandemic has reduced travel but led to an increase in household food and energy consumption. Previous studies have explored the changes in household consumption of food and energy during the pandemic; however, the economy-wide environmental implications of these changes have not been investigated. This study addresses the knowledge gap by estimating the life cycle environmental impacts of U.S. households during the pandemic using a hybrid life cycle assessment. The results revealed that the reduction in travel outweighed the increase in household energy consumption, leading to a nationwide decrease in life cycle greenhouse gas emissions (−255 Mton CO2 eq), energy use (−4.46 EJ), smog formation (−9.17 Mton O3 eq), minerals and metal use (−16.1 Mton), commercial wastes (−8.31 Mton), and acidification (−226 kton SO2 eq). However, U.S. households had more life cycle freshwater withdrawals (+8.6 Gton) and slightly higher eutrophication (+0.2%), ozone depletion (+0.7%), and freshwater ecotoxicity (+2.1%) caused by increased household energy and food consumption. This study also demonstrated the environmental trade-offs between decreased food services and increased food consumption at home, resulting in diverse trends for food-related life cycle environmental impacts.

Ecofriendly Dyeing of Textiles with Natural Dyes Extracted from Commercial Food Processing Waste Materials

ABSTRACT Textile wet processing industry is one of the dreadful polluters in the world. An alternative to hazardous synthetic dyes could be dyes derived from various natural sources such as plants, insects, and minerals. Additionally, agro-waste and food processing waste could serve as effective sources of natural dyes. The current study focuses on extraction of natural dyes from two commercial food processing waste materials, namely, the spent coffee grounds and the roasted peanut skin. The dyes were found to possess rich tannin content and were applied on silk, cotton, and nylon fabrics with and without the aid of mordants using water bath and ultrasonic bath. The dye exhaustion percentage is better in water bath dyeing for spent coffee grounds dye while its vice versa for the roasted peanut skin dye. Both the dyes show good color fastness to washing with silk and nylon fabrics while the grades are poor in case of cotton. However, the myrobalan and alum mordanted cotton fabrics exhibit very good color fastness to laundering. The color fastness to light is below average as is the case with most natural dyes. The spent coffee grounds dye give yellow to light brown shades while the roasted peanut skin dye give pink shades on cotton, silk, and nylon fabrics. With the use of ferrous sulfate mordant the dyes give different shades of gray color.

Audit And Analysis Of Waste Management In Baucau Municipality, Timor-Leste

Baucau is a municipality of Timor Leste, on the north coast in the eastern part of the country. The capital city is also named Baucau. The population in this municipality is 123,203 people (2015 census) and the area is 1,494 km². With a large population, which results in the production of waste increasing every day but the people in the municipality of Baucau face a lack of landfills and poor waste management. Many people in the municipality litter in drainage canals and public places whose sources come from household, commercial and office activities, so the researcher aims to 1.) examine the quantity and characteristics of waste from household activities and commercial activities in Bahu village (urban). , Tirilolo (peri-urban) and Caibada (rural) and 2.) studied the existing condition of waste management in the municipality of Baucau. From the results of the study, it was stated that in the three villages the composition of waste produced was organic waste, Metals, E-waste, Paper, cardboard, carton, Plastic bottles/PET, hazardous waste and glass. From household activities that produce waste, the highest is Bahu village (urban) with a total weight of 189,664 Kg, followed by Tirilolo (peri-urban) village with a total weight of around 155,224 Kg and the lowest is Caibada village (rural) reaching 106.655 Kg. From commercial activities consisting of 2 (two) hotels, 2 (two) supermarkets and 1 (one) restaurant. The three commercial activities that produce the most waste is supermarkets with a total waste weight of 86,323 Kg, followed by restaurants with a total weight of 57,886 Kg, and the lowest is hotels with a total weight of 6,799 Kg. The management of household, commercial and office waste in Baucau Municipality currently consists of three (3) parts: 1) Waste is transported by SMASA, 2) Discarded carelessly, and 3) Burned.

Leveraging the Entrepreneurial Method as a Tool for the Circular Economy: The Case of Wood Waste

New global and domestic policy and regulatory initiatives promoting a circular economy have renewed interest in the beneficial repurposing of commercial waste streams. Likewise, consumer trends and customers’ increased understanding of what they purchase, where it comes from, and what happens to it post-consumption have forced firms to consider reducing and reusing their production waste streams. The forest products industry is an exemplar of becoming more adept at reorganising and exploiting repurposed waste streams for beneficial reuse. This paper explores three case studies from the Australian forestry sector that illustrate how wood waste is being profitably repurposed as an input into other products. We use the lens of the entrepreneurial method to explore how firms recognise, strategically access, and exploit the sustainable opportunities that can range from sustainably sourced inputs to environmental-, social-, and governance-driven consumption and investments. Effectual logic allows the reconceptualisation of forestry waste streams into inputs for use in creating new commercial products and provides a theoretical framework. While the repurposing of wood waste is profitable for the forestry firm, we found that social and economic gains reach far beyond the region in which these activities occur. Innovations often stimulate other innovations, resulting in a virtuous cycle within regional Australia’s emerging circular economy.

Characterization of municipal solid waste residues for hydrothermal liquefaction into liquid transportation fuels

This paper presents and evaluates a new method for characterising municipal solid waste residues for assessing the performance of thermochemical conversion technologies to produce fuels. The method combines information from three complementary analytical techniques to estimate the quantity of key organic waste fractions and was demonstrated using two commercial waste residues: ‘BRDF’ and ‘Floc’ produced from the mechanical processing of domestic waste. Cellulose content (mostly paper and textiles) is estimated using acid hydrolysis, while thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR) are combined to determine the plastics (LDPE and PET) and non-volatile fractions such as lignin of the wastes. High mass balance closures were achieved for both residues, although the nature of the non-volatile fraction was difficult to verify. Hydrothermal liquefaction (HTL) of cellulose rich BRDF (34.0% cellulose) produced much higher biooil yields than Floc (26.8% and 12.2%, respectively), with a cellulose content of only 22.4%. In both cases, most of the plastic and non-volatile waste fractions partitioned into the solid HTL product, representing a potential method for separating the plastic fractions from other waste components. Importantly, this combined waste characterization method can be used for characterization of any municipal waste residue using acid hydrolysis, TGA and FTIR data, providing accurate information about feedstock composition. It enables comparison between different waste valorisation studies of complex waste residues.

The process to find a process for governance: Nuclear waste management and consent-based siting in the United States

In 2013, the United States (U.S.) Department of Energy (DOE) attempted to initiate a consent-based siting (CBS) approach to better engage diverse publics and thereby begin to remedy a legacy of technocratic decision-making and inequitable public engagement processes plaguing historical high-level nuclear waste siting efforts. DOE's remediation work included a contract with the Expert and Citizen Assessment of Science and Technology (ECAST) network to employ participatory technology assessment (pTA) to help co-create the CBS process with lay publics. In late 2016, the DOE terminated the process to develop a CBS process. To date, little in the public record explores DOE's novel foray into CBS. As researchers on DOE's aborted ECAST efforts, we situate the novel pTA process to create a CBS process amidst the technocratic political-historical context of commercial nuclear waste siting in the U.S. Lessons from ECAST's effort highlight persistent institutional barriers inhibiting U.S. capacity to more equitably approach the challenge of siting nuclear waste facilities. We identify the undermining consequences of DOE's focus on expediency; imposed limitations on the scope of CBS; bureaucratic obstacles to public input; a lack of continuity in values across executive administrations; and absence of top-level commitment to procedural and institutional learning, innovation, and adaptation. Through our case history and critical reflection, we aim to inform future efforts in the U.S. and beyond to overcome failed technocratic histories and instead steward participatory, equitable, and democratic processes to manage high-level nuclear waste.

Mitigation of Commercial Food Waste-Related Salinity Stress Using Halotolerant Rhizobacteria in Chinese Cabbage Plants

The use of commercial food waste in the Korean agricultural industry is increasing due to its capacity to act as an ecofriendly fertilizer. However, the high salt content of food waste can be detrimental to plant health and increase salinity levels in agricultural fields. In the current study, we introduced halotolerant rhizobacteria to neutralize the negative impact of food waste-related salt stress on crop productivity. We isolated halotolerant rhizobacteria from plants at Pohang beach, and screened bacterial isolates for their plant growth-promoting traits and salt stress-mitigating capacity; consequently, the bacterial isolate Bacillus pumilus MAK9 was selected for further investigation. This isolate showed higher salt stress tolerance and produced indole-3-acetic acid along with other organic acids. Furthermore, the inoculation of B. pumilus MAK9 into Chinese cabbage plants alleviated the effects of salt stress and enhanced plant growth parameters, i.e., it increased shoot length (32%), root length (41%), fresh weight (18%), dry weight (35%), and chlorophyll content (13%) compared with such measurements in plants treated with food waste only (control). Moreover, relative to control plants, inoculated plants showed significantly decreased abscisic acid content (2-fold) and increased salicylic acid content (11.70%). Bacillus pumilus MAK9-inoculated Chinese cabbage plants also showed a significant decrease in glutathione (11%), polyphenol oxidase (17%), and superoxide anions (18%), but an increase in catalase (14%), peroxidase (19%), and total protein content (26%) in comparison to the levels in control plants. Inductively coupled plasma mass spectrometry analysis showed that B. pumilus MAK9-inoculated plants had higher calcium (3%), potassium (22%), and phosphorus (15%) levels, whereas sodium content (7%) declined compared with that in control plants. Similarly, increases in glucose (17%), fructose (11%), and sucrose (14%) contents were recorded in B. pumilus MAK9-inoculated plants relative to in control plants. The bacterial isolate MAK9 was confirmed as B. pumilus using 16S rRNA and phylogenetic analysis. In conclusion, the use of commercially powered food waste could be a climate-friendly agricultural practice when rhizobacteria that enhance tolerance to salinity stress are also added to plants.

High-pressure compacted recycled polymeric composite waste materials for marine applications

Options for recycling fiber composite polymer (FCP) materials are scarce, as these materials cannot be normally recycled and are toxic when improperly disposed. Additionally, reducing water usage is an increasing concern, as the concrete industry currently uses 10% of the world’s industrial water. Therefore, building upon our previous work, this research explores the use of polymer hybrid carbon and glass composite waste products as reinforcements in high-pressure compacted cement. Our material used nearly 70% less water during manufacturing and exhibited improved durability and salt corrosion resistance. Compression strength tests were performed on high-pressure compacted materials containing 6.0 wt% recycled admixtures before and after saltwater aging, and the results showed that the material retained 90% of its original compression strength after aging, as it contained fewer pores and cavities. Our experimental work was supplemented by molecular dynamics. Simulations, which indicated that the synergetic effects of compaction and FCP admixture addition slowed the diffusion of corrosive salt ions by an average of 84%. Thus, our high-pressure compacted cement material may be suitable for extended use in marine environments, while also reducing the amount of commercial fiber composite polymer waste material that is sent to the landfill.Article HighlightsFiber composite waste was successfully recycled into denser, high-pressure compacted ordinary Portland cement materials.High-pressure compacted cement samples containing 6% recycled admixtures retained 90% of their compression strength after salt aging.The high-pressure compaction method utilized 70% less water during specimen fabrication.
