Lignin depolymerization often requires multiple isolation steps to convert a lignocellulose matrix into high-value chemicals. In addition, lignin structural modification, low yields, and poor product characteristics remain challenges. Direct catalytic of from date palm biomass was investigated. Production high value chemicals heavily depends on optimization different parameters method conversio...
• Characterizing and valorizing date processing waste are reviewed. Date (DPC) rich in chemicals nutrients. DPC have the potential to be used as a bioeconomy feedstock. We still need lab pilot studies before is valorized. Characterization of rarely considered. In Middle East North Africa, dates traditional economically valuable crop, playing an essential role people's daily diets. fruit product...
Background & Objectives: A large portion of medical wastes is dangerous, which is hazardous to the health of human beings, animals, plants, and environment. Considering the importance of this issue, this study aimed to evaluate the collection and disposal of medical waste in teaching hospitals of Sari, Mazandaran, Iran. Materials and Methods: In this cross-sectional, descriptive study, a qu...
Solid waste is a serious and growing problem thoughout tropical Asia. Waste management technologies and policies have not kept pace with the increase in waste production. The island of Bali in Indonesia is an atypical case in which both production and awareness of waste are relatively advanced. As such it is a useful case for exploring the wider problem and possible solutions. This article revi...
Slip instability and tensor instability are two kinds of failure modes of cemented waste rock backfills. In order to simulate the creep characteristics of cemented waste rock backfills, PFC was carried out. The results show that: rocks inside the models will have displacement under load. The expansion is caused by large lateral displacement of the rocks. A non-stationary creep model of cemented...
Greenhouse gas (GHG) emissions related to recycling of glass waste were assessed from a waste management perspective. Focus was on the material recovery facility (MRF) where the initial sorting of glass waste takes place. The MRF delivers products like cullet and whole bottles to other industries. Two possible uses of reprocessed glass waste were considered: (i) remelting of cullet added to gla...
Municipal solid waste collection is expensive and, in some cities, 46–85% of their whole waste management expenses are used for waste collection and transportation. Rapid urbanization and every day human actions generate a large amount of waste from residential, commercial, or industrial extents all over the world. Waste collection optimization can decrease the waste collection budget and envir...
Background: In Algeria the date wastes production is estimated at least 85.000 tones. Date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced. Objective: The aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. Materia...
