With the progress in technology and population, an enormous amount of agricultural and food waste is being generated throughout the world. In the past, food and agro‐wastes were either burnt off or allowed to rot in fields, but this can be potentially hazardous to the environment. Therefore, approaches with respect to their utilization, reuse, and processing need to be developed to enable the sustainable utilization of feedstock and reduce pollution. Agricultural wastes mainly comprise of cellulosic fibres possessing high fixed carbon content and multifunctional groups. Agricultural waste shows considerable applicability due to its high strength, environmentally benign nature, low cost, and ease of availability and reusability. All these characteristics have been researched upon in the past, in the sector of waste water management for the removal of heavy metals and dyes. Similarly, a variety of food and agro‐waste has been adopted as sources for new drug leads or important phytochemicals with different therapeutic benefits. Agro‐waste can also be employed for enzyme immobilization after proper modification. Apart from this waste cooking oil comes under the category of food waste and can be processed to prepare alternate energy source such as biodiesel. This personal account summarizes the development, processing, and application of food and agro‐waste in the production of biodiesel, environmental remediation, curative medicine, and in the development of biocatalysts, by researchers in our laboratory.

The aim of this work was the optimization of the enzyme hydrolysis of potato peel residues (PPR) for bioethanol production. The process included a pretreatment step followed by an enzyme hydrolysis using crude enzyme system composed of cellulase, amylase and hemicellulase, produced by a mixed culture of Aspergillus niger and Trichoderma reesei. Hydrothermal, alkali and acid pretreatments were considered with regards to the enhancement of enzyme hydrolysis of potato peel residues. The obtained results showed that hydrothermal pretreatment lead to a higher enzyme hydrolysis yield compared to both acid and alkali pretreatments. Enzyme hydrolysis was also optimized for parameters such as temperature, pH, substrate loading and surfactant loading using a response surface methodology. Under optimized conditions, 77 g/L of reducing sugars were obtained. Yeast fermentation of the released reducing sugars led to an ethanol titer of 30g/L after supplementation of the culture medium with ammonium sulfate. Moreover, a comparative study between acid and enzyme hydrolysis of potato peel residues was investigated. Results showed that enzyme hydrolysis offers higher yield of bioethanol production than acid hydrolysis. These results highlight the potential of second generation bioethanol production from potato peel residues treated with onsite produced hydrolytic enzymes.

“…Similarly, carried out the dilute H 2 SO 4 hydrolysis of rice hulls at 122°C for 20, 40, and 60 min using 2% dilute H 2 SO 4 at 1:10 solid:liquid ratio and reported that FS concentrations (glucose) were achieved to be 26 g/L for 20 min, 29 g/L for 40 min, and 33.5 g/L for 60 min under the determined conditions. Niphadkar and Rathod were optimized the conventional three phase partitioning (CTTP) and ultrasound‐assisted three phase partitioning (UATTP) conditions for obtaining the extraction and purification of polyphenol oxidase (PPO) from waste potato peels. Their results showed similarity with us that UATPP gives the highest purification fold of 19.7 with 98.3% recovery of PPO at optimized conditions.…”

Lignocellulosic materials that are the most abundant plant biomass in the world have the potential to become sustainable sources of the produced value added products. Tea processing waste (TPW) is a good lignocellulosic source to produce the value added products from fermentable sugars (FSs). Therefore, the present study is undertaken to produce FSs by using ultrasound-assisted dilute acid (UADA) and dilute acid (DA) hydrolysis of TPW followed by enzymatic hydrolysis. UADA hydrolysis of TPW was optimized by response surface methodology (RSM) at maximum power (900 W) for 2 h. The optimum conditions were determined as 50°C, 1:6 (w/v) solid:liquid ratio, and 1% (w/v) DA concentration, which yielded 20.34 g/L FS concentration. Furthermore, its DA hydrolysis was also optimized by using RSM for comparison and the optimized conditions were found as 120°C, 1:8 solid:liquid ratio, and 1% acid concentration, which produced 25.3 g/L FS yield. Even though the produced sugars with UADA hydrolysis are slightly less, but it can provide significant cost saving due to the lower temperature requirement and less liquid consumption. Besides, enzymatic hydrolysis applied after pretreatments of TPW were very more economic than the conventional enzymatic hydrolysis in the literature due to shorter time requiring. In conclusion, ultrasound-assisted is a promising technology that can be successfully applied for hydrolysis of biomass and can be an alternative to the other hydrolysis procedures and also TPW can be considered as suitable carbon source for the production of value-added products like biofuels, organic acids, and polysaccharides. © 2016 American Institute of Chemical Engineers Biotechnol.
