Abstract. Bambusa Vulgaris or Bamboo is one of the rapidly growing woody plants among different species and not being utilized properly around the world. Hence, the utilization of bamboo for sustainable resource recovery is required to avoid deforestation. This study is focused on thermo-chemical treatment of bamboo waste to investigate the physico-chemical properties of generated products. Experiments were carried out in semi batch, four zone electrically heated, rotary kiln reactor, with reaction time of 90 minutes and heating rate of 25 °C/min, for yield optimization. Products were analyzed through TGA, XRF, SEM/EDS, GCMS and FTIR. From the GCMS study, it was found that the bio-oil obtained through thermo-chemical treatment, contains high amount of alcohols, aldehydes, ketone and phenolic compounds. XRF of biochar showed 11 % inorganic components, among them K and Ca were found to be the major elements. XRF and EDS results were in good agreement and confirmed high carbon content. Biochar had the calorific value of 30.97 MJ/kg, which makes it suitable as energy source for commercial applications. Biochar contained carbonyl (C=O), hydroxyl (HO-), and carboxyl (HOOC) groups, which are responsible for ion exchange reactions during soil amendment. Low ash and high carbon content along with high porosity promotes its usage as high value material in different non-agricultural applications. Additionally, high amount of carbon is beneficial for maximizing the carbon storage and making the process environmentally sustainable.

“…Another alternative is to convert waste into useful resources such as refuse-derived fuel (RDF). RDF is produced from a solid combustible waste fraction of MSW such as plastic, wood, pulp and organic waste by mechanical-biological treatment ( Bhatt et al, 2021 , Mustia et al, 2021 ). RDF can be used in industries and WtE power plants.…”

Solid waste management was explored in Asia’s last five decades, and the issues and challenges were identified. Waste generation has increased in all nations in the previous 50 years, although more recently, a declining trend has been observed in Japan and Korea. The composition has been predominantly organic, with 45–50% being kitchen waste. Material extraction and productivity to sustain the most populous part of the globe are explained. Waste management technologies have evolved, with more nations slowly transitioning from landfills to using waste-to-energy options. However, landfilling and open dumps are still the major disposal choice in most developing countries in Asia. Thus, the issues of concern include dumpsites management, the informal sector, waste collection, open burning and food waste. Changes (increasing trends) in the recycling technologies and quantum are evident, as seen in several country reports from India, Indonesia, Japan, Malaysia, Singapore, South Korea, Thailand and Vietnam. There are several issues and challenges for recycling, which are explored in the text. Lastly, the drivers that propel the whole scenario of waste management in Asia and the evolution of these drivers over time are discussed. Several recommendations are included to achieve sustainable waste management in Asia.
