The aim of this study is to present the optimum operating conditions for reducing energy consumption in the process of obtaining bio-oil from the mixture of sawdust, waste lubricating oil, lime, and commercial catalyst. In the study where the catalytic pressureless depolymerisation (also called Katalytische Drucklose Verölung – KDV) was applied, the operating conditions were analysed with response surface methodology. According to the analysis of variance results, a mathematical model was obtained for specific product yield (bio-oil amount/energy consumption g kWe−1). Effects of temperature (260°C–290°C), catalyst rate (1–2 wt.%) and reaction time (0.5–1 h) were investigated. The optimum conditions for the three independent variables (temperature, catalyst rate, reaction time) were 279 ± 2°C, 2 wt.% and 0.5 h, respectively. Maximum specific product yield was obtained as 970.17 g kWe−1. While the reaction time was the most effective regarding the amount of bio-oil obtained at 1 kWe energy consumption, the temperature was found to be the least effective. In addition to these, bio-oil obtained under optimum conditions were characterised and compared with standard diesel specifications.

In the recent past, there has been a renewed shift into biomass and other recycled waste sources for biodiesel production and utilization. This is a critical area of research and study in which this present work intends to review and identify gaps in literature by shifting the focus of review to non-plant based sources for biodiesel production. Traditional biodiesel feedstock sources have always presented a conflict of food security versus energy. This shift will be identified in literature to see if change to non-plant-based feedstocks sources has increased food security by discouraging the contribution of commercial farming for the production of biodiesel. This work will identify biodiesel families, generations, traditional and non-traditional feedstocks for biodiesel production. It will also discuss the non-edible biodiesel feedstocks sources in relation to waste to energy recovery. The other factor this work will review is to study how the use of non-plant based feedstocks such as municipal solid waste has improved environmental protection by reducing pollution and landfilling. In other words, this work will review the impact of Using waste municipal solid biomass resources such as waste tyres and waste plastics and changing them into energy sources. This review study aims at increasing environmental awareness, sustainability and reporting the progress made in waste to energy policy shift in many countries globally. This review will look at socio-economic opportunities in recycling besides the academic and research impacts of waste to energy policies adopted in many countries. The review will climax with a conclusion and future trends in waste to energy in relation to municipal solid waste resources.

“…Pyrolysis for bio-oil extraction is the thermal disintegration of organic substances in deficiency of oxygen, resulting in the conversion of organic materials into utilizable bio fuels and chemical feedstock (Sukumar et al 2015 andUresin et al 2019). This technique when functional with lignocelluloses materials results in charcoal, bio-oil and non-condensable gasses.…”

Biomass is a renewable resource utilized to produce bio fuel from bio waste. In this experiment, fixed bed fast pyrolysis is carried out on a model of mahua oil cake (MOC dimension) to conclude predominantly the consequences of pyrolysis temperature, MOC dimension and nitrogen gas flow rate from the pyrolysis yields. The temperature, MOC dimension and nitrogen gas flow rate were varied between 500 to 600 oC, 2 mm to 6 mm and 0.2 to 0.4 liter per min (lpm). The utmost oil yield of 25.90 wt % was attained for a nitrogen gas flow rate of 0.3 lpm, particle size of 4 mm and pyrolysis temperature of 550oC. The pyrolysis oil had a calorific value of 28180 KJ/kg. The pyrolysis gas may well be utilized as a gaseous fuel. In addition, the bio-oil was illustrated by elemental, gas chromatography/mass spectrometry (GC-MS) analyzer.
