Waste from Jackfruit has little economic value and often causes serious environmental problems. The conversion of jackfruit waste will help reduce waste treatment costs, provide a potential source of raw materials for the activated carbon (AC) and increase economic value. In this study, the ACs from the Jackfruit shell and pulp were synthesized by microwave assistance for removing organic dyes.

The aim of the work "Activated carbon derived from rice husk by NaOH activation and its application in supercapacitor" is to prepare a low-cost, high specific surface area activated carbon with microporous and mesoporous ranges using rice husk as the raw material. The effects of activation temperature on the specific surface area, pore structure, morphology and thermal stability of the AC samples have been examined. The AC samples were proved to be excellent electrode material for supercapacitor, hence solve the disposal and pollution problems of rice husk.

The wine-making industries produce millions of tons of residues (grape pomace) after fermentation, which represents a waste management issue both ecologically and economically. After juice extraction from grape fruit, grapes pomace collectively includes stems, seeds and skins that is discarded as waste accounted for 55 – 65 per cent of the fruit. The most important variety grown in Coimbatore district, Tamil Nadu state is Muscat Hamburg (local name is Panner grapes), hence this variety of grapes is used in the study.

This study aims to investigate the adsorption capacity of ammonium NH4 + , nitrite NO2 - and nitrate NO3 - onto rice husk biochar (RHB) obtained from 550 °C pyrolysis temperature in the context of using low-cost absorbent for recirculating aquaculture system (RAS). Raw RHB at its original size 5–8 mm has been chosen for testing its adsorption capacity as well as several key material properties (pHPZC, surface area, and elemental analysis).

Raw materials management can be defined as the function of business that is responsible for the coordination of planning, sourcing, purchasing, moving, storing and controlling raw materials in an optimum manner so as to provide services to customers at a minimum cost. Raw materials management enables companies to coordinate raw materials-related activities and control total raw materials costs through integrated systems. The raw materials management has the duties as follows: Purchasing; Selecting supplier; Valuation process; Reception process; Technical evaluation; Trade evaluation.

In the current context of eco-pollution, the substitute of conventional plastics with bioplastics is a big confront. On account of that, a non-growth associated PHB production study was conducted using Zobellella species under submerged fermentation process. As a result, Zobellella species showed the ability to accumulate 2.2g/L of PHB at pH 8. 0, temperature 37oC, salt concentration 2% in modified growth medium containing vitamins. Then, primary structural characterization of extracted polymer was conducted by FTIR analysis. The high intense peak was obtained at 1720.

Harvested paddy grain with high moisture content must be dried to about 12 per cent (w.b) within 24 hours for safe storage and milling. Approximately 9 per cent of paddy was lost due to outdated drying methods, milling, unscientific method of storage, transport and handling (Basavaraj et al., 2015). Mechanical drying is essential to maintain the quality of grain during storage to prevent the growth of bacteria and fungi and the development of insects and mites.

The increasing cost of microbial growth media has necessitated continuous search for more readily available culture media at affordable prices. The agricultural based industries are generate significant quantities of organic wastes and it is necessary to convert them to useful end products. It is now realized that these waste could be utilized as cheap raw materials for some industries or used as cheap substrates for microbiological processes.

The study of the economics of processing of barley into malt reveals that all the malt processing plants under study were operating at far below their intake capacity. For small size plant, total costs of running the plant, fixed, variable and raw materials costs accounted for 11.95, 8.11 and 79.94 per cent of the total costs, respectively. Whereas, for medium size plant, total costs of running the plant, fixed, variable and raw materials costs accounted for 11.30, 6.30 and 82.40 per cent of the total costs, respectively.

It was found that growth performance of agro-processing industries in Karnataka was unsatisfactory when compared with its other states. It is found that 48 per cent of the household expenditure in India is on food items and the demand for processed/convenience food is constantly increasing. With relatively cheaper labour, low cost of production, base for domestic and export markets could be set up. Processed products like packed polished wheat (atta) has widened the market, attracting multinationals like HALL and Pilsbury (a joint venture with Godrej).

It is of great knowledge nowadays that the use of fossil fuels is responsible for the emission of gases that intensify the greenhouse effect, which threatens the survival of the humankind. The gravity of this fact could be mitigated through the indirect use of solar energy for fuels derived from vegetable that can be planted and cultivated by the world of renewable and non -polisher. Microalgae play an important role in this regard, as they have promising characteristics as potential raw material for the production of biofuels, able to absorb large amounts of CO2 .

The present investigation highlights the feasibility of a polymer grafting process to enhance the durability and flame retardancy of rice straw towards application as a low cost roofing material. The success of this grafting methodology was perceived to depend upon a bi-step pre-treatment process encompassing delignification and inorganic salts dispersion. Subsequently free radical polymer grafting of acrylonitrile onto rice straw was implemented by immersion mechanism initiated by oxalic acid-potassium permanganate initiator.
