“…It can also be concluded that significant differences can be seen in the distribution of the thermal and elemental composition. Furthermore, the SWP can be identified as low density polyethylene (LDPE) from the elemental composition and the pattern of thermal degradation [52]. The SWP presented a heat release rate curve typical for intermediately thin non-charring materials of LDPE family [53].…”

Nigeria, being the world’s largest importer of diesel-powered gen-sets, is expected to invest in bio-fuels in the future. Hence, it is important to examine the thermal properties and synergy of wastes for potential downstream resource utilization. In this study, thermal conversion as a route to reduce the exploding volume of wastes from sachet-water plastic (SWP) and oil palm empty fruit bunch (OPEFB) biomass was studied. Thermogravimetric (TGA) and subsequent differential scanning calorimeter (DSC) was used for the analysis. The effect of heating rate at 20 °C min−1 causes the increase of activation energy of the decomposition in the first-stage across all the blends (0.96 and 16.29 kJ mol−1). A similar phenomenon was seen when the heating rate was increased from 10 to 20 °C min−1 in the second-stage of decomposition. Overall, based on this study on the synergistic effects during the process, it can be deduced that co-pyrolysis can be an effective waste for energy platform.

“…This material is of very little value, as it does not resemble biochar obtained from pyrolysis of biomass, and therefore should be disposed of. However, attempts to use these solid residues as additive in the production of epoxy composite have been mentioned in the literature (Sogancioglu et al, 2017).…”

Agricultural plastics are currently characterised by a predominantly linear take-make-dispose value chain, thus being a major stream of waste that contributes to significant environmental and economic issues. Therefore, policy makers have recently indicated the adoption of circular economy approaches as the way forward for plastics. This study addresses the problem of agricultural plastic waste as a major stream of landfilled waste by assessing the potential for recycling the plastic into higher value products through pyrolysis and by optimally designing the respective supply network to support this process. A Mixed Integer Linear Programming (MILP) model is developed to optimise the end-to-end supply network design, from the waste generation stage up to the end consumer of the produced material. The model is supported by experimental results on the pyrolysis performance for contaminated plastic samples. The model is applied in a case study of the Scottish agricultural sector to showcase its potential in assessing the feasibility and financial viability in addition to the positive environmental impact on agricultural plastic waste supply networks. The results demonstrate the potential of using the pyrolysis technology for agricultural plastic waste recycling as an example of a circular economy approach and the benefits of using the developed model for decision making purposes, as well as the potential for waste reduction and the implications for farmers' operations.

Biofuel is a renewable fuel and can be used as a replacement for diesel. Pyrolysis oil can be derived from non‐edible de‐oiled seed cakes. This investigation focuses on the exergy investigation of a compression ignition (CI) engine to maximize the work exergy (availability) and minimize the destroyed exergy, powered by Aegle marmelos (AM) de‐oiled seed cake bio‐oil blends. A dual blend of diesel and AM pyrolysis oil was taken in ratios, F0 = 100 + 0, F5 = 95 + 5, F10 = 90 + 10, F15 = 85 + 15, and F20 = 80 + 20 and were tested on a constant speed CI engine at standard compression ratio. The investigational analysis exhibited that a high amount of oxygen content in AM pyrolysis oil blends increased the brake thermal efficiency and decreased the brake‐specific fuel consumption compared with diesel (F0). The owing exergy efficiency was obtained from the F20 blend (57.21%) at 100% load (W). Based on the investigation, considering availability and performance behavior of F5, F10, F15, and F20 blends were suggested as suitable biofuel alternatives to diesel.
