Additional Income

The use of biomass to produce bioenergy and biomaterials is considered a sustainable alternative to depleting fossil fuel resources. The world tanneries consume 8–9 MT of skin and hide every year producing 1.4 MT of solid waste. Most of the solid biomass generated from tanneries is disposed of as waste in the environment using either landfilling or thermal incineration. Disposal of this waste into the environment affects the ecosystem, causing bad odor (air pollution) and has an antagonistic impact on the environment. Due to this, European Union legislation bans the landfilling of biomass. This study aims to comprehensively review the possible valorization routes of leather processing industry biomass into high-value biomaterials. Leather biomass (trimmings, shaving, splitting, and buffing dust) mainly contain 30%–35% collagen protein, which is produced by acid or alkali hydrolysis. The biopolymers obtained from leather industry biomass can be utilized in the production of several high-value materials. In addition, leather processing industry biomass also contains fat, which can be converted into a bio-surfactant, and other useful biomaterials. Keratin protein can also be extracted from the hair waste of hides and skins. The increased demand for biomaterials makes the using of leather industry biomass very attractive. From this study, it can be concluded that the conversions of leather processing industry waste to valuable biomaterial can protect the environment, generate additional income for leather industries, and pave way for sustainable and renewable biomaterials production.

Currently, the leather industry has to deal with very high costs for waste treatment and disposal. As a result, it is recommended to subject the organic protein waste from tanning to biochemical treatments for recycling in the industry. The degree of novelty lies primarily in the fact that the starting point of the promoted technologies is obtaining new complex products by processing organic waste and using it in tanneries. The lime fleshings resulting from the hide fleshing operation represents the highest amount of reusable leather material of approx. 25%. This paper presents an innovative process for the biochemical degradation of hide waste resulting from hide fleshing in order to obtain a retanning/filling agent used in leather processing.

       Corn as a food ingredient ranks second after rice, besides it is also used as animal feed ingredients and industrial raw materials. Low productivity of corn due to varied soil fertility and not using superior varieties. To increase high yields, fertilization is needed, both chemical fertilizers and organic fertilizers such as podsolic soil. The purpose of this study (i) to determine the response of growth and yield of maize to the provision of rubber processing industry waste on podsolic soil (ii) get the best dose of rubber processing industry waste for the growth and yield of corn plants on podsolic soil. The study was conducted in the village of Haruyan Seberang RT 05 Rw 02 Kec. Haruyan Kab, Hulu Sungai Tengah, from April - June 2012, used a Randomized Block Design (RBD) with 5 treatments and 5 replications, so that there were 25 experimental units. The factors tested were the administration of several doses of rubber industry waste, namely (k0) without treatment, (k1) 10 t.ha-1 = 3.4 kg.plot-1, (k2) 20 t.ha-1 = 6.8 kg.plot-1, (k3) 30 t.ha-1 = 10.2 kg.plot-1 and (k4) 40 t.ha-1 = 13.6 kg.plot-1. The results showed the response of corn stalk diameter aged 21 and 28 DAP, number of leaves aged 14 DAP and length of corn cobs planted; there was no response of plant height aged 14, 21 and 28 DAP, stem diameter of 14 DAP, number of leaves aged 21 and 28 DAP and weight of ear of crop on treatment of dosing of rubber industry waste. The best dose of rubber processing industry waste for growth and yield of corn plants is 40 t.ha-1 (13.6 kg.plot-1).

Harmful Effects

The leather industry is one of the heavy-polluting and hazardous industries that is creating toxic and harmful effects on the environment and human health by producing waste chemicals, tannery effluents, and various pollutants. Moreover, Tanning is the required stage to convert raw skin to durable and sustainable skin but most of the chemicals, salts, organic and inorganic toxic pollutants are produced. In commercial practices, Chrome tanning is the highly employed approach that uses a large number of basic chromium salts that becomes the major source of chromium pollutant in the environment. Chromium salt is not only harmful to the environment and ecology but also harms the human body such as causing respiratory problems, infertility and birth defects, skin and lung cancer of the workers. This article has presented two alternatives eco-friendly greener approaches of chrome tanning and waste management technique to reduce the toxic effect on the environment and human health. Firstly, to get rid of these harmful effects, the possible remedy of environmental and human health problems may be considered the vegetable tanning process. Vegetable tanning uses tannins (a class of polyphenol astringent chemicals), which occur naturally in the bark and leaves of many plants. Secondly, chrome tanning associate with ultrasound having a frequency range of 20–100 kHz is commonly employed for enhancing the physical processes and for performing chemical reactions. The basic principle associated with the process is an ultrasonic cavitation in dissolved media. Ultrasound decreases the consumption of conventional water and chemicals because it can also function as a physical activator resulting reduction in environmental pollution which is a prime concern nowadays to approach greener leather technology and eco-friendly leather processing. Furthermore, the possible waste management technique of chrome tanning helps to prevent pollution and ensure eco-friendly green technology of leather processing. Therefore, vegetable tanning and chrome tanning associated with ultrasound having proper waste management will be the viable and sustainable options for the tanners in the forthcoming future.
