Purpose: This Systematic Literature Review (SLR) investigates the utilization of tuber crop skins, specifically from yam, potato, taro, and cassava as an underexplored resource in circular agriculture. The study aims to assess their multifaceted applications across sectors such as animal feed, bioenergy, material science, wastewater treatment, and food innovation, addressing the overarching research question of […]
Purpose: Waste and waste disposal is a universal problem and attention is required in all ways. The plant generated waste (leaf litter) is also a type of organic waste that creates multiple issues in urban areas. Method: Vermicomposting is a suitable alternative safe, hygienic, and cost-effective disposal of organic solid waste with the help of […]
Purpose Composting is known since long for reducing the use of synthetic chemical fertilizers. These fertilizers are applied to the crops for the supply of required macro/micronutrients. The present study describes how to decompose biodegradable solid wastes quickly into compost without harming the environment. Method The microbial inoculums were developed from cow dung concentrate. The […]
Purpose Poultry industries produce a lot of feathers which are considered as waste and needs to be managed properly. Poultry feathers are rich with keratin protein and therefore they could be a source for good nitrogen fertilizer. Proper treatment of poultry feather waste (PFW) might be an environmental friendly solid waste management tool and a […]
Purpose In this study, vermicomposted tannery wastes were applied in the organic cultivation of sweet pepper in a greenhouse. The effects of this organic matter addition on plant development and on the distributions of Cr(III) and Cr(VI) in plant tissues and organs were assessed. Methods In a greenhouse, organic sweet peppers were cultivated adding vermicomposted […]
Purpose: Vegetable waste (VW) could cause environmental problems if not properly managed. Due to rural living conditions and a relatively low residence density, VW is usually disposed of in landfills. Waste management should be engineered in a way to process the waste into value-added products in a sustainable manner. This review evaluates four bioprocessing techniques […]
Purpose The experiment was performed to determine the effect a commercial potting mix partially replaced with dewatered aquaculture effluent had on tomato transplant growth. Methods The experiment was designed as a 2 9 3 factorial and evaluated two water sources (water-soluble, inorganic fertilizer or municipal water) and three soilless substrates with 0, 5 or 10 […]
Purpose The aim of this research was to evaluate the suitability of pineapple waste for production of decomposable nursery pots. Methods The experiment was completely randomized, with three replicates and eighteen formula treatments. Treatments consisted of varying ratios of pineapple waste to binder, including 2:1, 1:0 (fresh pineapple waste), 1:1, 1:1.5, and 1:2; the textures […]
Purpose The study evaluates and provides an overview of the nutritional importance of 19 selected food wastes as aids in human/livestock/soil/plant health. Methods Nitric acid-digested extracts of food wastes belonging to four different classes (fruits, vegetables, oilseeds and beverages) were analysed for different elements in an inductively coupled plasma mass spectrometer. Results Our study recommends […]
Purpose A pilot composting project was initiated as part of a 200 tons/day solid waste recycling plant with active involvement of several local stakeholders. The project aimed at introducing compost production and use in the village of Al Jalameh, Palestine. This paper describes the successes and lessons from the pilot project. Methods Based on the […]
