A Food Waste-Derived Organic Liquid Fertiliser for Sustainable Hydroponic Cultivation of Lettuce, Cucumber and Cherry Tomato.

We previously reported a sustainable food waste management approach to produce an acceptable organic liquid fertiliser for recycling food waste called "FoodLift." This study follows our previous work to evaluate the macronutrients and cation concentrations in harvested structural parts of lettuce, cucumber, and cherry tomatoes produced using food waste-derived liquid fertiliser (FoodLift) and compare them against commercial liquid fertiliser (CLF) under hydroponic conditions. N and P concentrations in the structural parts of lettuce and the fruit and plant structural parts of cucumber appear to be similar between FoodLift and CLF (p > 0.05), with significantly different N concentrations in the various parts of cherry tomato plants (p < 0.05). For lettuce, N and P content varied from 50 to 260 g/kg and 11 to 88 g/kg, respectively. For cucumber and cherry tomato plants, N and P concentrations ranged from 1 to 36 g/kg and 4 to 33 g/kg, respectively. FoodLift was not effective as a nutrient source for growing cherry tomatoes. Moreover, the cation (K, Ca, and Mg) concentrations appear to significantly differ between FoodLift and CLF grown plants (p < 0.05). For example, for cucumber, Ca content varied from 2 to 18 g/kg for FoodLift grown plants while Ca in CLF-grown cucumber plants ranged from 2 to 28 g/kg. Overall, as suggested in our previous work, FoodLift has the potential to replace CLF in hydroponic systems for lettuce and cucumber. This will lead to sustainable food production, recycling of food waste to produce liquid fertiliser, and will promote a circular economy in nutrient management.

Biodegradation of low-density polyethylene plastic waste by a constructed tri-culture yeast consortium from wood-feeding termite: Degradation mechanism and pathway

Polyethylene (PE) is one of the most common synthetic polymers, and PE waste pollution has been an environmental and health concern for decades. Biodegradation is the most eco-friendly and effective approach for plastic waste management. Recently, an emphasis has been placed on novel symbiotic yeasts isolated from termite guts as promising microbiomes for multiple biotechnological applications. This study might be the first to explore the potential of a constructed tri-culture yeast consortium, designated as DYC, isolated from termites for the degradation of low-density polyethylene (LDPE). The yeast consortium DYC stands for the molecularly identified species Sterigmatomyces halophilus, Meyerozyma guilliermondii, and Meyerozyma caribbica. The LDPE-DYC consortium showed a high growth rate on UV-sterilized LDPE as a sole carbon source, resulting in a reduction in tensile strength (TS) of 63.4% and a net LDPE mass reduction of 33.2% compared to the individual yeasts. All yeasts, individually and in consortium, showed a high production rate for LDPE-degrading enzymes. The hypothetical LDPE biodegradation pathway that was proposed revealed the formation of several metabolites, including alkanes, aldehydes, ethanol, and fatty acids. This study emphasizes a novel concept for using LDPE-degrading yeasts from wood-feeding termites for plastic waste biodegradation.

Machine learning approach for automated beach waste prediction and management system: A case study of Mumbai

Asia’s coastlines are choking in waste. The region is now home to many of the world’s most polluted beaches. The populous Indian Cities are growing economically but in an unsustainable manner. With Mumbai counted among topmost polluted beaches in the world, it is the need of the hour to take necessary steps for effective waste management by systematic data analysis for deriving useful information from waste generation patterns. The major objective of the study is pattern recognition and beach waste quantum prediction based on 5 years data, with a frequency of daily waste collection. The size of the training data set is 1,661 days and the validation data set is 335 days. The influence of population trend, waste generation during festivals, special days, weekends, and seasonal variations form the basis for the analysis. Using machine learning algorithms, the study identifies and investigates data patterns for the case study of Dadar-Mahim beach. Data frequency and weights are correlated with occurrence of events, festivals, weekends, and seasons. Exploratory Data Analysis (EDA) is employed for data preprocessing and wrangling, followed by a Random Forest algorithm-based model for the prediction of waste generated at Dadar-Mahim beach. The major challenges in data prediction are limited data availability and variation in the dates of festivals and holidays as well as lack of waste segregation information. Despite the above-mentioned challenges, the observations indicate the model’s average accuracy for making predictions of around 60%. The Graphic User Interface (GUI) developed based on the model provides a user-friendly application for predicting the total daily generation of beach waste with reasonable precision. On the basis of the model’s outcome and applicability, a schematic approach for efficient beach waste management is proposed. The recommendations would serve as guidelines for Urban Local Bodies (ULBs) to automate the collection, transport, and disposal of beach waste.

Comparing VFA Composition, Biomethane Potential, and Methane Production Kinetics of Different Substrates for Anaerobic Fermentation and Digestion

Solid waste is one of the largest sources of greenhouse gases (GHGs) today. The carbon footprint of landfills also has a large impact on global warming. Therefore, it is becoming more urgent to study the possibility of better environmentally friendly approaches for solid waste management and its safe disposal. The digestion of solid waste is a biological process that breaks down the organic content of the solid waste and thus stabilizes it. It also allows the recovery of valuable resources (such as biogas) and the utilization of stabilized waste in various industries. In this study, six substrates were studied to determine their biomethane potential (BMP) in anaerobic digestion. The substrates were fermented and digested anaerobically, and the biogas production was measured. The methane yield of food waste substrates had a higher methane yield between 354 and 347 mL/g-TCOD, and a biodegradability of 89–87%. Wastewater sludge substrates yielded between 324 and 288 mL/g-TCOD with a biodegradability of 81–73%. A kinetics analysis using first-order and Gompertz models was performed for biodegradation and methane production.

Alternative Determination of TPS Waste Management in Karangkates Village, Malang Regency Based on Local Wisdom

Karangkates Village has problems in handling waste where as the population increases, the amount of waste generated increases. The Temporary Waste Storage Site (TPS) is no longer able to accommodate the rate of waste generation, so a waste management plan at the TPS is needed to help with existing waste handling problems. There are 2 alternative waste management approaches that are expected to be used as a solution to solving the waste problem, namely TPST and TPS3R. The concept of integrated waste management includes the activities of reducing, sorting, collecting, utilizing, transporting and processing. TPS 3R is carried out by processing wet and dry waste which aims to reduce the amount of waste generation. Waste management at TPS in general as an effort to empower the community requires special stages that lead to local wisdom. Efforts to reduce household waste Waste disposed of in excavations based on its type, namely organic and inorganic waste. Organic waste is left alone because over time it will decompose along with the soil and make it fertile, while inorganic waste is burned because it cannot decompose naturally. This is pro-environmental behavior. With increasing globalization and lack of land in the region, waste is picked up by garbage collectors and dumped at the final collection point. Environmental knowledge, local wisdom, and environmental attitudes are classified as very significant and make a real contribution to people's behavior in managing waste in housing.

From expired metformin drug to nanoporous N-doped-g-C3N4: Durable sunlight-responsive photocatalyst for oxidation of furfural to maleic acid

Following the waste management approach and increasing contamination by the pharmaceutical industry, expired metformin drug, a nitrogen-rich organic scaffold, was employed as a nitrogen dopant for the synthesis of valuable N-doped g-C3N4 under very mild conditions. To this end, various amounts of expired metformin drugs were combined with urea, providing N-doped g-C3N4 with a high N/C ratio, confirmed by X-ray photoelectron spectroscopy (XPS). It was found that the presence of the waste doping agent not only resulted in nitrogen-rich graphitic carbon nitride but also elegantly improved its physical and optical properties such as surface area and the rate of recombination of photogenerated charge carriers, as well as band gap. The photocatalytic potential of prepared samples was evaluated in the oxidation of furfural under sunlight irradiation. In this line, prepared material containing 1 wt% expired metformin drug, which benefits from high surface area and efficient separation of photo-generated electron-hole pairs, was a more efficient photocatalyst to deliver the maleic acid product with high selectivity and yield (98% yield) using hydrogen peroxide as an oxidizing agent. In addition, the photocatalytic system exhibited high stability and could be reused seven times. The key role of hydroxyl and superoxide radicals in the progression of the reaction was established based on control experiments along with proposing the mechanism pathway. Indeed, this study demonstrates a deeper understanding of waste management concepts in chemical applications, particularly in the synthesis of privileged catalysts using green and sustainable approaches.

Economic performance of biogas production and use from residues co-digestion in integrated 1G2G sugarcane biorefineries: Better electricity or biomethane?

Recovering bioenergy through anaerobic digestion (AD) has become the most attractive waste management approach in modern industrial plants, because both the environmental adequacy and the provision of clean biogas-derived energy can be successfully met. Recent investigations have particularly shown the energetic benefits of residue co-digestion in sugarcane biorefineries, which significantly enhances biogas production compared to mono-digestion schemes. This work carried out an economic analysis to assess the feasibility of producing biogas from residues co-digestion in an integrated 1G2G (first and second generation) ethanol biorefinery and its application in electricity and biomethane (BioCH4) production. Scenarios considered the mono-digestion of 1G vinasse in the season (MD1-base scenario), the mono-digestion of 1G vinasse in the season followed by the mono-digestion of 2G vinasse in the off-season (MD2), the co-digestion of 1G vinasse, filter cake and deacetylation liquor in the season followed by the co-digestion of filter cake and deacetylation liquor in the off-season (CD1), and finally the co-digestion of 1G vinasse, filter cake and deacetylation liquor in the season followed by the mono-digestion of 2G vinasse in the off-season (CD2). The scenarios comparison aimed to investigate the potential to implement year-round biogas production in sugarcane processing plants. The results showed that co-digestion-based scenarios (CD1 and CD2) had the best performance for producing both electricity and BioCH4 from biogas, with the higher profitability related to the latter. Scenario MD1 scenario presented a negative net present value (NPV) for both electricity and BioCH4 production, whilst only BioCH4 production would be profitable in scenario MD2. The NPV for electricity production in scenario CD2 reached USD 9 million (4-fold higher than mono-digestion of 1G vinasse reported in the literature), whilst a peak of USD 45 million was calculated for BioCH4 production. In addition, the current bioelectricity production from bagasse burning showed to be much more economically unfavorable compared to biogas production and use. Biogas recovery from residue co-digestion has been increasingly confirmed as an attractive alternative for energy generation within 1G2G ethanol biorefineries, maintaining year-round production and consisting of a robust BioCH4 source, with great potential to be used both as a biofuel to supply the plant’s fleet and to replace natural gas via injection into the grid.

Insect biorefinery: A circular economy concept for biowaste conversion to value-added products

With rapid growing world population and increasing demand for natural resources, the production of sufficient food, feed for protein and fat sources and sustainable energy presents a food insecurity challenge globally. Insect biorefinery is a concept of using insect as a tool to convert biomass waste into energy and other beneficial products with concomitant remediation of the organic components. The exploitation of insects and its bioproducts have becoming more popular in recent years. This review article presents a summary of the current trend of insect-based industry and the potential organic wastes for insect bioconversion and biorefinery. Numerous biotechnological products obtained from insect biorefinery such as biofertilizer, animal feeds, edible foods, biopolymer, bioenzymes and biodiesel are discussed in the subsequent sections. Insect biorefinery serves as a promising sustainable approach for waste management while producing valuable bioproducts feasible to achieve circular bioeconomy.

Development of waste-to-energy through integrated sustainable waste management: the case of ABREN WtERT Brazil towards changing status quo in Brazil.

In the context of circular economy, it is known that once waste is generated, it should be subject to proper treatment for recovering material or energy before being disposed. Many countries worldwide, especially developing countries such asBrazil, have been struggling to effectively apply sustainable waste management in municipalities and still rely on dumpsites and unsuitable landfills. Misinformation, aweak legal framework, lack of financial resources and poor infra-structure as well as pressure from organizations profiting from the expansion of landfills are some factors contributing to the preservation of the negative status quo: the "landfill culture". Material recovery, i.e., recycling and composting, is applied to less than 5% of Brazilian municipal waste, while 95% is disposed ofin landfills or dumpsites. In this context, ABREN WtERT(Waste-to-Energy Research and Technology Council) Brazil was created in 2019 as the first permanent organization formed to promote the development of energy and material recovery from waste focused on thewaste-to-energy(WTE) market. In this paper, the strategy proposed and implemented by the organization towards changing the status quo in Brazil through an integrated sustainable waste management approachis described. The proposed strategy integrates theconcepts of Sustainability and Circular Economy for minimizing landfill disposal (avoiding methane emissions) and maximizing material/energy recovery. Among others, the approach focuses on changing the public opinion regarding thermal treatment facilities, mainly incinerators, which has been wrongly linked to pollution, excessive public expenditures and considered a harm to the recycling industry. The activities performed by ABREN include engaging public and private institutions, enhancing education, leading the publication of research and business studies, gathering industry members and academy experts, as well as creating strategic alliances with players around the globe. As a result, within a few years, major outcomes were achieved in Brazil, such as: (i) changes in the legal framework, (ii) launching of a specific public auction category for sponsoring electricity production from WTEfacilities, and(iii) establishment of official targets for municipalities to decrease landfill disposal and increase recycling/biological treatment and energy recovery from thermal treatment. Among the national goals, it should be highlighted the target regarding the increase from zero to 994MW of electricity production from municipal solid waste, which will require building dozens of new WTEfacilities. Global outcomes are expected as well since Brazil is the seventh largest country of the globe and the most influential in Latin America. Internationaland national business deals should thrive due to the need of operational skillsandtechnology imports, and the avoidance of carbon emissions will positivelyreflect the world climate. In parallel, there is also potential for the academy to benefit from research projects and investments if the WTEnational industry is to be developed in the long term.

The paper presents an in-depth analysis the characteristics of MSW and methods for classifying MSW, as well as the advantages and limitations of physical, chemical, and biological disposal techniques, such as landfill, hazardous waste disposal, chemical treatment, immobilization, anaerobic digestion, and composting. Furthermore, the review highlights the importance of an integrated waste management approach that combines these methods with waste reduction, reuse, and recycling strategies to minimize the environmental and public health impacts of waste disposal.

Increasing Data Availability for Solid Waste Collection Using an IoT Platform based on LoRaWAN and Blockchain

Solid waste management is one of the problems that has gained greater prominence in recent years. This topic has been discussed with greater emphasis in conjunction with environmental issues, driven by changes in the most diverse fields provided by the recent post-pandemic scenario. However, due to traditional or inefficient waste management approaches, most trash bins placed in cities can be seen as overflowing. Therefore, a remote monitoring system is needed to alert the level of garbage in bins to the relevant authority for waste clearance. In this scenario, the Internet of Things (IoT) paradigm plays a vital role in improving smart city applications by tracking and managing city processes. This paper implements a solution based on Low-Power Wide-Area Network (LPWAN) and blockchain technologies to provide the required data available for increasing efficiency in solid waste collection. Finally, this paper provides an evaluation of the proposed architecture related to latency and throughput metrics.

Enhancing food operator intention on specialty café using 3R waste management approach for eco-enzyme production as an implementation of SDGs 12 (Study on Akkar Specialty Cafés)

Handling café business waste is essential for environmental protection, especially for organic food waste. After all, organic food waste decomposes quickly and produces methane gas, which has a pungent odor if not appropriately managed. This research analyzes and describes the waste management activities of specialty café businesses, starting with showing the development potential for managing by-product waste to increase added value and increase customer awareness. The research method used is descriptive qualitative analysis based on literature study, observation, interviews, and analysis of other supporting documents. The practice of waste management can positively impact the amount of waste generated from the café business because the amount of waste that must be submitted to the landfill can be reduced and provide by-products to increase income and café aesthetics. Waste management can be implemented by collecting and sorting waste and then processing it into by-products, one of which is by making eco-enzymes. The impact of this activity is that café businesses can educate employees and consumers to care more about the environment through simple waste management. The limitation of this study is that the research was conducted without a waste treatment trial process. Although this research is locally focused and qualitative, the results and methods of this research can be used to guide the implementation of wiser and more sustainable café business waste management.

Production and optimization of Jeevamrutha bio-fertilizer formulations for soil fertility and its role in waste minimization

Intense inorganic fertilization practices exponentially detriment upon the soil health and enhance input costs of production. Henceforth, organic bio-fertilizers such as Jeevamrutha being developed with rurally available low cost nitrogen and carbon sources are necessary to serve as alternate fertilization systems for soil nutritional enrichment and plant growth. Associated mechanism with respect to the interaction of precursors such as jaggery and gram flour in Jeevamrutha bio-fertilizer have not been vividly explored in the prior art. Considering this lacunae, the article addresses the optimization of these precursors for the affirming of their fundamental role in the nutrient characteristics of the Jeevamrutha bio-fertilizer. Thereby, the article targets the optimization of Jeevamrutha bio-fertilizer formulations using the Central Composite Design (CCD)-based statistical tool for summer and winter seasons. The corresponding Total Kjehdahl Nitrogen (TKN), Ammonium Nitrogen (AN) and Phosphate (P) during the summer (0.67%, 427.56 mgL−1 and 1405.78 mgL−1) and the winter (0.28%, 135.86 mgL−1 and 1046.75 mgL−1) seasons were achieved in North-East India. This study provides critical insights for waste-to-value added product development through the utilization of rurally available substrates for nutrient enhancement of soil that will aid waste management approach. Also, in comparison with the control group (0%) and various treated samples for the optimized formulation (25%, 50%, 75% and 100% v/v), the highest Germination Index (GI) of 87.87% was obtained for the 50% (v/v) treated sample (mung bean) indicating its efficacy towards phytotoxic effects. Thereby, the methodology and results aim to revolutionize agricultural systems and improve soil health due to reduced cost and preparation time and wider utility of land and waste precursors in comparison to other organic fertilizer preparation techniques.

OVERVIEW OF RECYCLING RUBBER TIRE AS AGGREGATES IN CONCRETE: AN APPROACH FOR SOLID WASTE MANAGEMENT

The difficulties related to non-biodegradable waste management raise the danger of environmental and health issues since millions of worn rubber tires are discarded yearly. Over the past several years, the building industry has been compelled to use this material combined with cement-based products due to the material's accessibility and vast manufacturing volume. Due to its promising properties, including enhanced ductility, damping ratio, and vibration resistance, recycling used tire rubber as a partial replacement of natural stones in concrete is a topic of intense research. Conversely, the rubber aggregator reduces the mechanical characteristics and workability of the resulting concrete mixtures. This study reviews the feasibility of using shredded rubber tire waste as a partial replacement for traditional aggregates in concrete. The properties of the rubberized concrete are discussed with respect to various ratios of rubber tire waste and traditional aggregates. The results of previous studies showed that using rubber tire waste as an aggregate in concrete significantly reduces the mechanical properties of the concrete, including its compressive strength, tensile strength, and flexural strength. On the other hand, using rubber tire waste as an aggregate reduces the weight of the concrete, which may have potential benefits for structural design. Overall, the study suggests that recycling rubber tire waste as an aggregate in concrete is a viable approach for solid waste management and can also provide environmental and economic benefits.

KNOWLEDGE, ATTITUDE AND PRACTICES OF FOOD WASTE MANAGEMENT AMONG FOODSERVICE OPERATORS IN PETALING JAYA UTARA (PJU) 9 AND 10, SELANGOR

Malaysia generated about 17,000 tonnes of food waste daily in 2021 and 24% of this waste was still edible. Wasting food is not only just an economic or humanitarian concern but it also affects the environment and can increase carbon footprint and biodiversity losses. Although many food waste campaigns have been launched in Malaysia recently, there is still a gap of adequate knowledge and practices as well as the right attitude in local communities especially among foodservice workers, towards food waste prevention. Therefore, the level of knowledge, attitude and practices (KAP) on food waste among foodservice operators were assessed in this study to identify the factors that contribute to food waste generation among foodservice operators so that effective corrective methods could be developed to address this problem. A self-administered questionnaire surveying 136 respondents of foodservice operators in PJU 9 and 10, Petaling Jaya, Selangor using convenience sampling were conducted. The results showed that the respondents had a good level of knowledge (86%) while attitudes were at a moderate level (76.5%) and practices of food handling were identified to be at a low level (48.5%). The evaluation of the relationship between the three elements of KAP on the generation of food waste revealed that there was a weak positive relationship between knowledge and attitude (r = 0.26, p &lt; 0.05) as well as between knowledge and practices (r = 0.21, p &lt; 0.05). However, a weak negative relationship (r = - 0.22, p = 0.01) was noted in the relationship between attitude and food handling practices. These results indicate that high knowledge of food waste generation as a factor may not help change the attitude patterns and practices of foodservice operators in food waste mitigation. In this regard, positive and negative reinforcements may be one of the best approaches for sustainable food waste management among foodservice operators, for example, offering incentives to those who produce less food waste and levying a penalty to those who produce more may act as a deterrent.

Mechanical Properties and Waste Management Approaches of Banana in India

Abstract: Around 27% of the contribution to the world's banana production is done by India only. This directly leads to an increase in waste loss. Despite its tremendous utilization, nutritional &amp; health benefits, and mechanical properties of fibres which allows the growth of the economy in the country, the problem of waste management in India is big. Usually, the leaves, pseudostems, rachis and banana peel are the major solid waste-loss of bananas which corresponds to its maintenance and harvesting practices. Its waste loss amounts to roughly 114 million metric tonnes worldwide, contributing to environmental issues such as the excessive emission of greenhouse gases. Thus, this review paper focuses on the the mechanical properties of pseudostem fibres which offer a significant bioresource to create a variety of high-value goods, including rope, cordage, fishing nets, mats, packaging materials, paper sheets, textile fabrics, bags, tablecloths, handicrafts, absorbent materials, and polymer composites. The research on banana fibre-reinforced composite materials is a new field of research and is still open to be explored. These composite-based fibres have a good potential to be used in various sectors like construction, automotive, machinery, etc., due to their high mechanical strength. Many advancements in the manufacturing techniques of its fibres are under process to ease the process. However, still, hand layup, compression moulding, and filament winding are the processes which are followed. Thus, this review paper focuses on the mechanical properties &amp; utilization of banana pseudostem fibres and approaches to combat the main challenges of waste management and to provide sustainable solutions to achieve social, economic, and environmental benefits.

Phytotoxicity evaluation of nutrient-fortified pomegranate peel powders prepared from food waste and their feasibility as biofertilizers

AbstractPomegranate peel powder (PPP) is increasingly used as a bioadsorbent to decontaminate wastewaters due to its adsorptive characteristics. The application of nutrient-fortified bioadsorbents as alternatives to chemical fertilizers can provide an innovative and eco-friendly approach for sustainable waste management. Nevertheless, there is extremely limited information regarding their effects on the growth of agricultural crops. We investigated the effects of raw and nutrient-fortified PPPs on oilseed rape (Brassica napus). Our results showed that the concentration-dependent in vitro phytotoxicity of high PPP doses (germination indices were 109.6%, 63.9%, and 8.9% at the applied concentrations of 0.05%, 0.5%, and 5%) was diminished by the application of nutrient-fortified PPPs (germination indices were 66.0–83.4% even at the highest doses). In pot experiments, most PPP treatments (especially Raw-PPP and the mixture of N- and P-fortified PPPs) promoted the development of aboveground plant parts. Reorganization of the pattern of protein tyrosine nitration in the root tissues indicated that the plants were acclimated to the presence of PPPs, and thus, PPP treatment induced no or low-level stress. Our findings confirmed that several doses of PPP supplementation were beneficial for the model crop plant when applied in soil. We anticipate that our study will be a foundation for future investigations involving more plant species and soil types, which can contribute to the introduction of nutrient-fortified PPPs as sustainable biofertilizers.

Life cycle and end-of-life waste management of disposable diapers: a mini-review

Waste management is a crucial priority issue for all countries in this environmentally conscious era. Proper waste management of disposable diapers is one of the issues at the forefront. The unprecedented growth of the world urban population has left many cities grappling with disposable diapers clogging landfills. It is a problematic issue that if not mitigated could overburden existing waste management systems. This mini-review article aims to critically review relevant life cycle assessment studies (LCA) on single-use disposable diapers and the environmental impact incurred at each stage of its life cycle. Different technical and non-technical disposable diaper waste management approaches have been explored in literature, but studies directed towards pyrolysis conversion of disposable diapers post-consumer waste are notably very scarce. The review further examines the potential of pyrolysis as an end-of-life waste management option for disposable diapers. Finally, this study highlights gaps in the literature and recommends the scope for future research.
