Fruit peel waste (FPW) is abundantly available from the agricultural and food processing industry and has been studied in recent past as an adsorbent. This paper critically reviews the reported work and investigates various FPW-pollutant systems. The study includes statistics of FPW generation, modification, characterization, adsorption ability, recovery/regeneration, and modeling (isotherms, kinetics, and thermodynamics) of batch adsorption. It is found that orange and banana peels are the most extensively studied adsorbents, whereas Pb2+ and methylene blue are the most efficiently removed pollutants, the Langmuir and Freundlich adsorption isotherms provide the best fit in most of the cases, and in general, pseudo-second-order kinetics is followed. There are very limited column studies and no report on commercial plant. Though the reproducibility of the results is poor, FPW has a great potential in the wastewater treatment due to its abundant and cheap availability. FPW can be used for removal of heavy metals and dyes; however, removal of organic and gaseous impurities needs further investigation.

Fruit and vegetable peel (FVP) wastes are a commonly generated organic waste from both households and food-processing industries. However, FVPs are low-cost lignocellulosic materials that have some potential for reutilization. For its particular reutilization, the characterization of FVP is essential. In this regard, the present study provides a detailed physico-chemical characterization of commonly used FVPs such as pomegranate, pineapple, watermelon, garlic, green pea and pigeon pea. The materials were characterized by SEM, FTIR and TGA/DTG. Various properties of these materials, such as porosity, particle density, bulk density, surface charges, point of zero charge, surface pH, water absorption capacity and BET surface area were determined. The BET surface area of FVP was found in the range 1.0-1.4 m(2)/g. Water absorption capacity was highest for watermelon peel (11.5 ml/g), while it was lowest for pigeon pea peel (5.5 ml/g). Point of zero charge and surface pH of all FVPs were in the acidic range 3-6. The surface of FVP was irregular and rough with some pores. Thermal analysis showed that FVPs are thermally stable below 150 degrees C. The results of this study provide an understanding of the properties of FVPs and suggest that the materials can be used as a low-cost adsorbent.

We report on the adsorptive removal of benzoic acid (BA) and salicylic acid (SA) using banana peel (BP), an abundantly available agricultural waste material, for the first time. BP was characterized by proximate analysis, FT-IR, scanning electron microscopy, BET surface area, and XRF. The number of basic sites on BP (4.9mmolg(-1)) is relatively more than acidic sites (0.75mmolg(-1)). The Langmuir uptake capacity values obtained are 6.62mgg(-1) for BA and 9.80mgg(-1) for SA. A mechanism for binding acid molecule to the BP surface is proposed.

However, recent research suggests that BP is a valuable source of bioactive compounds, which can be converted into value-added products. This article reviews the conversion process of value-added products from BP and provides an outline on the chemical composition of BP and its possible applications. In addition, we also discuss the - utilization of BP as a substrate to produce animal feed, biofertilizer, dietary fibers, clean energy, industrial enzymes, as well as its use in the synthesis of nanomaterials. Based on the research conducted so far, it is obvious that BP has a wide variety of applications, and thus, developing a biorefinery approach to adequately utilize BP will help realize its economic benefits to the fullest. Based on the valorization of BP, a scheme for BP biorefinery has been proposed. A material balance for BP biorefinery for 1-ton bone-dry BP is presented and our results show that 432 kg of protein or 170 kg of citric acid, 170 kg of pectin, 325 m(3) of ethanol, and 220 m(3) of methane can be produced.1 aPathak, Pranav, D.1 aMandavgane, Sachin, A.1 aKulkarni, Bhaskar, D. uhttps://library.ncl.res.in/content/valorization-banana-peel-biorefinery-approach01842nas a2200157 4500008004100000245006200041210006100103260000800164300001200172490000800184520132000192100002301512700002701535700002601562856009601588 2017 eng d00aFruit peel waste: characterization and its potential uses0 aFruit peel waste characterization and its potential uses cAUG a444-4540 v1133 aGlobally, India is the leading producer of fruits. Fruits after consumption leave a peel which is a nuisance to the environment as a solid waste. In this article, commonly available large volume-fruit peels (FP) (viz. banana, orange, citrus, lemon and jackfruit) were investigated for surface, physical and chemical characteristics with a view to propose their valorization in detail. Each FP was characterized by proximate and ultimate analysis, porosity, particle density, bulk density, point of zero charge (pH(pzc)), surface pH, surface charges, water absorption capacity, BET surface area, scanning electron microscopy, Fourier transform infrared spectroscopy and TGA/derivative of thermogravimetric. The BET surface area of FP is very less, between 0.60 and 1.2 m(2)/g. The pH(pzc) and surface pH values of orange peel (OP), citrus peel (CP), lemon peel (LP) and jackfruit peels (JFP) are in the range of 3-4. The pH(pzc) value and surface pH of banana peel (BP) is closer to 7. The order of surface acidity is OP > LP > CP > JFP > BP. From TG curves it is clear that FPs are stable below 150 degrees C. The results will be useful for rational design, when FP is used as a substrate for bioactive compounds, phenolic antioxidants, organic acids, enzymes, biofertilizer, production of energy and as adsorbents.1 aPathak, Pranav, D.1 aMandavgane, Sachin, A.1 aKulkarni, Bhaskar, D. uhttps://library.ncl.res.in/content/fruit-peel-waste-characterization-and-its-potential-uses01543nas a2200229 4500008004100000022001300041245004900054210004800103260000800151300001400159490000700173520088400180653002401064653001601088653001601104653001701120653002501137100002301162700002701185700002601212856007501238 2019 eng d a1877264100aWaste to wealth: a Case study of papaya peel0 aWaste to wealth a Case study of papaya peel cJUN a1755-17660 v103 a

Papaya is a popular fruit consumed worldwide and well-known for its food and nutritional values. It is used in food industries for the production of jams, jellies, etc. As a result, these industries generate huge amounts of papaya peel (PP) and seeds as by-products, which are typically considered a waste, and thus discarded. However, our current investigation indicates that PP is a valuable source of bioactive compounds, which can be converted into many value-added products. In this article, we review the physicochemical composition and valorization of PP. PP can be utilized to obtain many value-added products by fermentation (e.g., biofuels, adsorbents, dietary fibers, biomedicine, biomaterials). The biorefinery approach for PP will definitely increase the value of this waste by producing an array of value-added products and achieving zero waste generation.
