“…The values of compressive strength for all types of briquettes in this study meets the requirements given in both studies mentioned. The high compressive strength of the hybrid briquettes makes them safer to store or transport and will not break or wear off very easily, in agreement with Nwabue et al [90].…”

The objective of this research was to investigate the quality of hybrid briquettes developed from corncobs (CC) and oil palm trunk bark (OPTB) under a low-pressure densification technique. The materials were combined in varying ratios of CC to OPTB (100:0, 75:25, 50:50, 25:75, 0:100) and wastepaper pulp (10% by weight) was added to each mixture as a binder. The briquettes were produced using a manually operated 20-tonne hydraulic piston press at 28 °C temperature and ≤7 MPa compaction pressure. The mechanical strength of the briquettes was determined by the drop test and compression test methods, while a bomb calorimeter was used to determine the calorific values. The results showed that the physical properties of hybrid briquettes ranged from 9.24–10.00% moisture content, 0.38–0.40 g/cm3 density, and 87.60%–92.00% water resistance. Mechanical strength showed a 98.28%–99.08% shatter index and 18.47–21.75 MPa compressive strength, while calorific values ranged from 16.54–16.91 MJ/kg. The hybrid briquettes fared better than the CC briquettes. The significance of this study lies in the production of briquettes with suitable physical, mechanical and thermal properties by utilizing OPTB which have hitherto not been used, mixed with corncobs. This could bring substantial environmental and socio-economic benefits to rural communities of the developing countries.

“…These aspects leave refuse-derived fuel as the only possible solution. Nwabue et al [1] demonstrate how recovery of the plastic wastes into refuse-derived fuel by incorporation in the production of bio-coal briquettes can be considered as part of waste management options, especially in developing countries. Similar studies were conducted by Gayo [30], and Lu and Chiang [31].…”

“…However, Wanjiku Mukui [59] provides a thorough analysis based on the country's latest plastic inventory. That study focuses on (1) Given: CEV = Circular Economic Value; MIM = ratio of imported plastic raw materials (IM rm ) to the total volume of plastic manufacture inputs (T rm ); MEX = ratio of exported plastic products (EX mo ) to the total volume of plastic manufacture outputs (T mo ); LCM = ratio of non-recyclable plastic waste (NR pw ) to the total plastic waste amount (T pw ); CML = ratio of non-recycled recyclable plastic waste (NR rpw ) from the total recyclable plastic waste amount (T rpw ); WCL = ratio of non-collected plastic waste (NC pw ) to the total plastic waste amount (T pw ); and WPL = ratio of non-recycled collected plastic waste (NR cw ) to the collected plastic waste amount (T cpw ).…”

Designing Business Solutions for Plastic Waste Management to Enhance Circular Transitions in Kenya

2018

Least-developed countries face many challenges regarding their plastic waste management systems. In 2017, Kenya imposed a selective ban targeting manufacturers and consumers of plastic carrier bags. However, this selectivity does not avoid the continuous use of other plastic products. The present paper states that circular priorities, which have been defined to advanced economies, would not be entirely valid for the rest of the world. While high-income countries face only the impacts of their own consumption, developing nations must endure the externalities of these developed economies. Thus, the focus of the least developed part of the world must not be on reducing its relatively normal (or even low) consumption, but to manage its surplus material flow. According to the employed circular evaluation methodology (CEV-Circular Economic Value), the circularity level in Kenya's plastic material flow stands on a rather low stage with 32.72%. This result outlines the linear deficiencies of the plastic waste management system and urges the prevention of further material leakage (such as energy use). Through the Business Model Canvas (BMC) approach this study offers a holistic business solution which can improve the system's sustainability.

“…Biomass can be produced using agricultural waste [5]. Briquettes produced were good alternative to fuel wood for out-door and in-door cooking and for mitigation of deforestation, desertification and environmental pollution and degradation [6] [7]. It was also used to convert the wastes to a valuable material.…”

The ultimate source of energy for crucial activities like cooking, heating and parboiling process is burning wood and other agricultural products. Due to growing populations utilizing resource of combustible biomass materials will finally result in insufficiency of those materials until certain measures are taken to secure them. It mainly focuses on the minimization of pollution especially land, water and air and to avoid the deforestation mainly for many fuels for burning. The product taken is the by-product, which is obtained from the residue left after letting the cotton industrial waste for reuse. The raw materials used are cassava waste, coconut shell, groundnut shell, cotton waste and cow dung with thirty different mix ratios. The briquettes were made without using any binder. Using hydraulic pressure with UTM given to produce the briquettes are 5.0 kN/cm 2 , 5.6 kN/cm2 and 6.0 kN/cm2 . Good energy content has been obtained when the pressure for producing briquettes at 5.6 kN/cm2 .These briquettes are mainly used for industrial boiler running and cooking purpose.
