Valorising Agri-Waste – Agriculture produces an unsustainable amount of waste, so how does the bioeconomy let us derive value from it?
For every kilogram of “usable” crop produced in agriculture, between 1 and 2.5 kilograms of residue is also produced. Of course, some of this residue must remain in the field or be used elsewhere on the farm in order to maintain a healthy ecosystem, but that which isn’t used thus is an unavoidable waste. Minimising waste is one of the central tenets of sustainability: the waste ...

Adsorption characteristics of methylene blue onto agricultural wastes lotus leaf in bath and column modes
The adsorption potential of lotus leaf to remove methylene blue (MB) from aqueous solution was investigated in batch and fixed-bed column experiments. Langmuir, Freundlich, Temkin and Koble–Corrigan isotherm models were employed to discuss the adsorption behavior. The results of analysis indicated that the equilibrium data were perfectly represented by Temkin isotherm and the Langmuir saturation ...

Biosorption of Methylene Blue onto spent corncob substrate: kinetics, equilibrium and thermodynamic studies
This study focuses on the possible use of the spent corncob substrate (SCS), an agricultural waste used after the cultivation of white rot fungus Pleurotus ostreatus, to adsorb Methylene Blue (MB) from aqueous solutions. A batch adsorption study was carried out with variable solution pH, adsorption time, temperature and initial MB concentration. It was found that MB uptake was favorable at pH ...

Application of date palm trunk fibers as adsorbents for removal of Cd+2 ions from aqueous solutions
In this research raw date palm trunk fibers were used to adsorb cadmium ions from aqueous solutions. The date palm trunk fibers are considered as agricultural waste which is available in huge quantities in the Kingdom of Saudi Arabia. In order to assess the feasibility and the efficiency of using this as an adsorbent, a series of experiments were conducted in a batch adsorption method. The ...

Adsorption of anionic dyes in aqueous solution using chemically modified barley straw
An agricultural waste derived adsorbent was prepared by chemically modified barley straw with NaOH and a cationic surfactant hexadecylpyridinium chloride monohydrate (CPC). The prepared adsorbent, BMBS, was used for removal of anionic dyes; Acid Blue (AB40) and Reactive Blue 4 (RB4) from aqueous solution in a batch adsorption system. The adsorbent was characterized by FT-IR and elemental ...

Recycling agriculture wastes of ramie stalk as bioadsorbents for Cd2+ removal: a kinetic and thermodynamic study
In this study, we exhibit the recycling of agriculture wastes of ramie stalk as bioadsorbents for Cd2+ removal. Based on our experimental results, it is realized that Cd2+ adsorption to ramie stalk is highly pH sensitive, indicating the adsorption is driven by surface complexation reaction. The high adsorption capacity of ramie stalk toward Cd2+ (qm = 10.33 mg g−1, 0.09 mol-Cd g−1), which ...

Pesticide removal from wastewater
In this study, the removal of 2,2 ? dichlorovinyl ? o,o ? dimethyl phosphate (DDVP) from wastewater by adsorption was carried out. DDVP is an organophosphorus insecticide widely used in agriculture in Turkey. Adsorbents used in the study were agricultural waste straw, wood chips and ground corncobs. Adsorption of DDVP onto these materials from wastewater was evaluated by using a batch system. ...

Biosurfactant rhamnolipid enhanced modification of corn stalk and its application for sorption of phenanthrene
The application of modified agricultural wastes for removing polycyclic aromatic hydrocarbons (PAHs) from water is gaining a growing interest. However, most modified methods using synthetic chemicals may cause secondary pollution. To overcome this limitation, in this study, a rhamnolipid modified corn stalk (RL-CS) for the removal of phenanthrene (PHE) from aqueous solution was prepared using ...

Growth and reproduction of Eisenia foetida in various industry waste sludge during vermicomposting: a laboratory investigation
The effect of industrial waste sludge on growth and reproduction on earthworm Eisenia foetida was studied. Earthworms, cow-dung and soil were collected from local farm, and industrial waste sludge from industries – United Phosphorus Ltd. (UPL), Enviro Technology Ltd. (ETL), Deepak Dye Industry (DDI) and Doshi Ion Industry (DII). Chemical properties, biomass gain, natality and hatchling of E. ...

Biotransformation of rice straw by Phanerachaete chrysosporium and the related ligninolytic enzymes
Biotransformation of lignin is related to the biomass utilisation of agricultural wastes. Ligninolytic enzyme from Phanerochaete chrysosporium plays an important role in biodegrading lignin and is specially concerned by researchers. The aim of the study is to optimise the conditions for producing ligninolytic enzymes in solid-state fermentation, and to biotransform the rice straw for the biomass ...

Our finest gold: agrarian perspectives on urban technology from the mid-19th century to present-day ecocyclical society
This study examines how agricultural science, from the mid-19th century to present day, has maintained that urban technology should be designed in response to agricultural interests. Recycling of urban waste was regarded in the mid-19th century as a way of augmenting the fertility of the soil, while at the same time solving the sanitary problems of urban communities. By about 1900 this ...

Significance of Phosphorus in Anaerobic Digestion Residuals Recovery
Gas production and energy potential typically dominate the spotlight in the anaerobic digestion (AD) technology world, while benefits of residues and nutrient management from AD are overshadowed. However, utilizing AD residues and considering the value of properly managing nutrients, such as phosphorus, may make-or-break projects considered uneconomical based on energy production value alone. ...

EPA proposal to change reporting of hazardous substances from farm animal waste
EPA has proposed a rule change to provide an administrative reporting exemption for air releases of hazardous substances -- primarily ammonia and hydrogen sulfide -- from animal waste at farms. The aim is to enable authorities to better focus their attention on hazardous substance releases that require emergency response while reducing reporting burdens on America’s farms. EPA’s proposed rule ...
