The feasibility of utilizing industrial waste to produce soil stabilizer with high added value is discussed from technical effect, economic benefit and production and management mode. Principle of design of the stabilizer with industrial waste is offered based on the properties of stabilized soil structure formation and its special demand on stabilizer components; the examples of the stabilizer composition are presented, and the performance/cost ratio of the stabilizers are compared with that of cement. Reasonable production and management mode for industrially producing the stabilizer with industrial waste is discussed also. It is suggested that as long as appropriate industrial waste is selected intentionally to meet the special demand on the stabilizer composition needed to form stabilized soil structure, the soil stabilizer with high performance/cost ratio can be obtained. It is advised that the stabilizer should be designed individually according to the properties of the soil to be stabilized, the stabilizer should be produced with the production mode of mixing multi-components and adopt the management pattern of incorporating designing, production and sale.

In this paper how to utilize industrial wastes in soil stabilizer preparation with high added value is discussed. Firstly the characteristics of stabilized soil structure formation process and its special demand of stabilizer components were explored. Based on this, the design thought for the soil stabilizer prepared with industrial wastes is proposed and the examples are presented. Then technical, economical and environmental comprehensive index is analysed. Only if stabilized soil structure formation process was understood deeply and industrial waste was chosen properly according to the special demand of stabilized soil structure to components, the change from waste to resource can be realized. And then the stabilizer can be prepared with excellent performance, cost, environment effect and comprehensive benefit.

Biotechnological Processes

The improvement of biotechnological processes capable of transforming agro-industrial waste into products with high added value has stood out in the area of renewable energies, promoting positive impacts to the environment. Thus, the present work evaluated the influence of nickel on the conversion of fermentable sugars, present in the green coconut shell hydrolyzate (GCSH), into butanol and other products. Fermentation assays were performed at 37 °C, starting with 19.4 g.L-1 of sugars and 1.0 g.L-1 of inoculum (C. beijerinckii). The GCSH was supplemented with tryptone, yeast extract, ammonium acetate, minerals and phosphate buffer. Two conditions were tested: with and without addition of nickel. Concentrations of sugars (glucose and xylose), intermediate products (organic acids), acetone, butanol, and ethanol were determined by high performance liquid chromatography (HPLC). The results show that the butanol production was higher from GCSH without addition of nickel, reaching a concentration of 2.14 g.L-1 of butanol. Therefore, the presence of nickel in the hydrolyzate was not favorable in the production of butanol under the studied process conditions.

The agroindustry generates a large amount of waste. In postharvest, food losses can reach up to 50%. This waste represents a source of contamination of soil, air, and bodies of water. This represents a problem for the environment as well as for public health. However, this waste is an important source of bioactive compounds, such as phenolic compounds, terpenes, and β-glucans, among others. Several biological activities have been attributed to these compounds; for example, antioxidant, antimicrobial, gut microbiota, and immune system modulators. These properties have been associated with improvements in health. Recently, the approach of using these bioactive compounds as food additives for aquaculture have been addressed, where it is sought that organisms, in addition to growing, preserve their health and become disease resistant. The exploitation of agro-industrial waste as a source of bioactive compounds for aquaculture has a triple objective—to provide added value to production chains, reduce pollution, and improve the well-being of organisms through nutrition. However, to make use of the waste, it is necessary to revalue them, mainly by determining their biological effects in aquaculture organisms. The composition of bioactive compounds of agro-industrial wastes, their biological properties, and their application in aquaculture will be addressed here.

The problem of the environment is a serious issue that must be addressed by the government and the community as a supervision and reporter of each of the activities of the destroyer of the environment. The pollution and environmental damage continue to increase in line with the increased industrial activity or similar substances; surely the situation needs to get the protection of the law.  The pollution or environmental damage, mostly in the context of running a commercial business and often is also the attitude of rulers and the entrepreneurs who do not run or neglecting the obligations of their obligations in the management of the environment. This research is a descriptive quantitative i.e. with provides an overview of the company that takes the environment around the enterprise. Data collection method in this investigation using bibliographical study (Library Research). The types of data used a secondary data that consists of primary legal materials and secondary legal materials. The waste is the remaining exiles who produced from real production activities in the production scale of domestic or household and production on a larger scale. Industrial waste is a remnant of the captives process of production in certain industries. Industrial waste requires the handling and managing seriously in considering the impact will greater emanate than with domestic waste. The industry is a business or management activities of raw materials or half-goods to be the end goods that have added value to get the benefits. The assembly of the business and repairing is a part of the industry also. The results of this industry do not only in the form of goods but also in the form of services.

Peanut meal (PM) has recently emerged as a potential protein source for wood adhesives, owing to superior features such as high availability, renewability and eco-friendliness. However, the poor properties of unmodified PM-based wood adhesives, compared with their petroleum-derived counterparts, limit their use in high-performance applications. In order to promote the application of PM-based wood adhesives in plywood industry, urea (U) and epichlorohydrin (ECH) were used to enhance the properties of the adhesives and the modification mechanism was investigated. PM-based wood adhesives made with U and ECH were shown to possess sufficient water resistance and exhibited higher apparent viscosity and solid content than without. Fourier-transform infrared spectroscopy results suggested that U denatured PM protein and expose more reactive groups, allowing ECH to react better with U-treated PM protein to form a dense, cross-linked network which was the main reason for the improvement of the properties. The crystallinity increased from 2.7% to 11% compared with the control, indicating that the molecular structure of the resultant adhesive modified by U and ECH became more regular and compact owing to the cross-linked network structure. Thermogravimetry tests showed that decomposition temperature of the protein skeleton structure increased from 307°C to 314°C after U and ECH modification. Scanning electron microscopy images revealed that using U and ECH for adhesives resulted in a smooth protein surface which prevented moisture penetration and improved water resistance. PM-based adhesives thus represent potential candidates to replace petroleum-derived adhesives in the plywood industry, which will effectively promote the rapid development of eco-friendly adhesives and increase the added value of PM.
