As plastic manufacturing companies continue to expand, so does the production of plastic waste. However, repurposing plastic waste is possible through the plastic pelletizing recycling system. This system converts plastic scraps into usable clean raw material in a closed-loop recycling process. What is Plastic Pelletizing? Plastic pelletizing is the process…

The pelletising process and its effects on pellet quality depend on several factors that characterise a material, the pre-treatment method, and the technical parameters of the machine working units (Jezerska et al., 2019). The proper combination of these factors leads to the production of durable and strong pellets (Whittaker and Shield, 2017).

process consumes large amount of energy (Figures 2a and 2b) and therefore may render a chromite mine uneconomic. However, in terms of coke consumption, the technology has been designed to work without using coke as a reductant (Figure 5). Therefore to use this technology for producing ferrochrome, there is the need to reach a compromise

5.3.2 Pelletising. One of the main problems involving the use of biomass as a fuel is its low density, which leads to high handling and transport costs. This is a major factor which would limit the large-scale use of biomass for energy production. Pelletising is a mechanical compacting process which has been shown to address this issue.
