“…It will not only waste resources, but also pose a potential threat to the ecological environment. 10,11 Therefore, it is necessary to convert these wastes into high value-added materials, collagen fibers (CF) derived from animal skin tissues are considered as a renewable biomass material with abundant active groups, such as −NH 2 , −C(O)NH 2 , −COOH, and −OH, making it a potential excellent adsorption material. [12][13][14][15] However, it is still limited by the shortcomings of the material itself, such as limited active sites, easy swelling and low specific surface area.…”

Environmental challenges, especially dye wastewater produced by printing and dyeing industry, pose a serious threat to global public health, and it is an urgent problem to realize harmless treatment of dye wastewater. Here, the combination of covalent organic framework materials (TpPa-1) and biological matrix materials (CF) was explored for the adsorption of dyes for the first time. The functional ACF-TpPa-1 composite adsorption materials were successfully prepared with collagen fiber (CF) made of leather waste as matrix, ethylenediamine (EDA) and covalent organic framework material (TpPa-1) as modified raw materials. It’s structure and properties were characterized by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM). The experimental results showed that ACF-TpPa-1 had an adsorption capacity of 257.98 and 449.54 mg/g for acid fuchsia and reactive blue 19, respectively. It also showed excellent adsorption/desorption performance and repeatability after six cycles. As a collagen-based dye adsorbent with pH response, it has potential application prospects in the treatment of dye wastewater.

“…Therefore, novel environment friendly extraction methods need to be developed. Devaraj et al [67] developed acid/alkaline assisted fat extraction method for the industrial application without using organic solvent. The fleshing wastes contain 260 g fatty oil, by using acid hydrolysis method, 254 g fatty oil with extraction efficiency of 98% was attained which carried out with 4% of H 2 SO 4 at 120°C for 1.5 h. Whereas, acid hydrolysis assisted soxhlet process obtained 260 g fatty oil with 100% extraction efficiency at 80°C for 1.5 h using less solvent and time.…”

Leather making is the process of converting raw hides into leather. Amounts of solid waste containing hazardous and high value components are generated during this process. Therefore, the elimination of the potential pollution and resource utilization of leather solid waste are the primary research hotspots. Herein, we comprehensively review the recent advances in the resource utilization of leather solid waste generated from chrome tanning including the utilization of tannery hair waste, untanned solid waste, chrome-containing leather solid waste, tannery sludge and finished leather waste, emphasizing on the general and novel utilization approaches. Finally, the remaining challenges and perspectives were summarized, in order to accelerate the development of resource utilization of leather solid waste.

In recent years, the waste animal fats are drawing attention as potential feedstocks for biodiesel production. The exploit of rendered waste animal fats as feedstocks could help to further decrease the price of biodiesel compared to other feedstocks. These fatty wastes can be transformed into ethyl or methyl esters by the esterification and/or transesterification process with the aid of different types of catalysts. In this outlook, an endeavor has been made in this work to describe the significance of fatty wastes of chicken, fish, beef, goat, sheep, pig and duck in the biodiesel production process. This study also extends to present the distinct techniques used by researchers to convert these fatty wastes into biodiesel.
