Abstract:

Abstract Tapioca industrial solid waste is a very abundant and high cellulose content that makes solid waste from tapioca industrial an alternative material substituted to coal. The low-calorie value of solid waste is around 2783 Kcal/kg, which requires an effort to increase calorie value—increasing the calorie value of solid waste by carbonization in the pyrolysis furnace. The study of solid waste with pyrolysis to replace coal and improve the calorie value similar to commercial coal needs to be done. In this study, the influence of time and temperature on the carbonization of solid waste was

Currently, Indonesia is experiencing a waste crisis due to the continuously increasing volume of waste generation, which leads to the rapid overfilling of landfill sites. One of the potential solutions for utilizing landfill waste is the production of Refuse-Derived Fuel (RDF), an alternative fuel derived from solid waste.

The share of paper in MSW changed from 21.4% in spring to 9.7% in autumn. More paper in spring is due to discarded student notebooks at the end of a school year, as well as spring household cleaning.

Abstract:

Solid waste silica fume was used to replace fly ash by different ratios to study the early-age hydration reaction and strength formation mechanism of concrete. The change pattern of moisture content in different phases and micro morphological characteristics of concrete at early age were analyzed by low field nuclear magnetic resonance (LF-NMR) and scanning electron microscope (SEM). The results showed that the compressive strength of concrete was enhanced optimally when the replacement ratio of solid waste silica fume was 50%. The results of LF-NMR analysis showed that the water content of mo

Gas transport parameters such as gas diffusivity (Dp/D0), air permeability (ka), and their dependency on void space (air-filled porosity, ε) in a waste body govern convective air and gas diffusion at solid waste dumpsites and surface emission of various gases generated by microbial processes under aerobic and anaerobic decompositions. In this study, Dp/D0(ε) and ka(ε) were measured on dumping solid waste in Japan such as incinerated bottom ash and unburnable mixed waste as well as a buried waste sample (dumped for 20 years).

Abstract. Open burning of household and municipal solid waste is a frequent practice in many developing countries. Due to limited resources for collection and proper disposal, solid waste is often disposed of in neighborhoods and open-burned in piles to reduce odors and create space for incoming waste. Emissions from these ground-level and low-temperature burns cause air pollution, leading to adverse health effects among community residents. In this study, laboratory combustion experiments were conducted to characterize gas and particle emissions from 10 waste categories representative of thos
