Environmental pollution is one of the major concerns throughout the world. The rise of industrialization has increased the generation of waste materials, causing environmental degradation and threat to the health of living beings. To overcome this problem and effectively handle waste materials, proper management skills are required. Waste as a whole is not only waste, but it also holds various valuable materials that can be used again. Such useful materials or elements need to be segregated and recovered using sustainable recovery methods. Agricultural waste, industrial waste, and household waste have the potential to generate different value-added products. More specifically, the industrial waste like fly ash, gypsum waste, and red mud can be used for the recovery of alumina, silica, and zeolites. While agricultural waste like rice husks, sugarcane bagasse, and coconut shells can be used for recovery of silica, calcium, and carbon materials. In addition, domestic waste like incense stick ash and eggshell waste that is rich in calcium can be used for the recovery of calcium-related products. In agricultural, industrial, and domestic sectors, several raw materials are used; therefore, it is of high economic interest to recover valuable minerals and to process them and convert them into merchandisable products. This will not only decrease environmental pollution, it will also provide an environmentally friendly and cost-effective approach for materials synthesis. These value-added materials can be used for medicine, cosmetics, electronics, catalysis, and environmental cleanup.

Factors Influencing

The paper examined the willingness of smallholder cassava processors to pay for value-added solid wastes management solutions in Nigeria. We employed a multistage sampling procedure to obtain primary data from 403 cassava processors from the forest and Guinea savannah zones of Nigeria. Contingent valuation and logistic regression were used to determine the willingness of the processors to pay for improved waste management options and the factors influencing their decision on the type of waste management system adopted and willingness to pay for a value-added solid-waste management system option. Women constituted the largest population of smallholder cassava processors, and the processors generated a lot of solid waste (605–878 kg/processor/season). Waste was usually dumped (59.6%), given to others (58.1%), or sold in wet (27.8%) or dry (35.5%) forms. The factors influencing the processors’ decision on the type of waste management system to adopt included sex of processors, membership of an association, quantity of cassava processed and ownership structure. Whereas the processors were willing to pay for new training on improved waste management technologies, they were not willing to pay more than US$3. However, US$3 may be paid for training in mushroom production. It is expected that public expenditure on training to empower processors to use solid-waste conversion technologies for generating value-added products will lead to such social benefits as lower exposure to environmental toxins from the air, rivers and underground water, among others, and additional income for the smallholder processors. The output of the study can serve as the basis for developing usable and affordable solid-waste management systems for community cassava processing units in African countries involved in cassava production.

The Impact

Uncontrolled infrastructure development may produce excessive carbon emission and scarcity of natural resources. The reuse of waste materials in general promotes material ecology and the cradle-to-cradle concept. The utilisation of industrial waste in the development of advanced materials promoting the extensive research on sustainable building components. The main objective of this research is to investigate the potential of utilising local industrial waste, Solid Waste Fly Ash (SwFA) and Paint Sludge (PS) as target material in replacing laterite soil that is non-renewable natural resources. Standard industrial size bricks were fabricated consist the combination of Laterite Clay, SwFA and PS (LSP) at 50:25:25 ratios. The results for engineering and environmental properties were within the acceptable of engineering standards and performances. This test result suggests potential used of SwFA and Paint Sludge as substitute to clay for unfired brick. This will certainly contribute to the recycling of SwFA and industrial sludge (Paint Sludge andpossibly others) and hence to minimise the impact of these by-product to the environment if send to landfill. The manufacture of unfired bricks can exploit locally available waste materials and can be used in certain applications of low load bearing situation. This research also suggests innovation and enhanced waste management and contribution towards the concept of green building components.  Keywords: Industrial waste, eco-bricks, durability, thermal, acoustic

Solid Waste management begin at the household as waste of consumption and ended as a new form of waste product or recycling. Based on its value chain the subsequent process will have distict differences with manufacturing product. Value chain of manufacturing product will characterize as value added chain along the chain, where every side of the chain will generate positive chain. In the other hand, some parties of waste management value chain will negative value existed. Some parties in this chain will generate negative value solely because they must establish some cost for wipe the waste. Dissimilarities between value chain on product and waste will contribute to discrepancy between parties. Main purpose of this research is to identify value chain from solid waste management using value chain development. Another purpose to accomplished is to resolve discrepancy in value chain.  Research results shown that household is the parties that experiences negative value. To minimize the discrepancies there should be an action towards household

Developing country municipal solid waste management is complex, managed by multiple institutions, prone to socio-political disruptions and often requires frequent and rapid estimates of good functioning. Estimating the quantity, composition and status of municipal solid waste found at unauthorized dump sites helps in diagnosis and in improving solid waste management system. The objective of this study was to find occurrences of unauthorized dump sites and to determine quantity, area, height of dumps, waste density and waste composition at these sites. A total of 452 locations were identified and quantification of solid wastes was carried out at 268 locations by determining waste spread area, measuring dump height and density by multiple techniques. Mixed dumped wastes at site was physically segregated into twelve waste categories (organic fraction, plastic, construction debris, paper, cloth, glass, leather, metal, rubber, biomedical waste, burnt waste and industrial wastes). It was estimated about 213310 Mg of wastes were dumped in 452 unauthorized dump sites. The composition of waste dumped in unauthorized sites have 41.3% of construction debris followed by 28.9% of organic waste and other fractions constituted the remaining. The waste composition at dump site suggests less efficient recycling systems and the possible direction for the system improvements.
