Production of Briquettes from a Blend of HDPE (High Density Polyethylene) Plastic Wastes and Teak (<i>Tectona grandis </i>Linn<i>. </i>f) Sawdust Using Different Natural Adhesives as the Binder

Abstract

HDPE (High Density Polyethylene) is one type of plastics that has been used in many various applications. We frequently used it in our daily life, such as plastic bag, dairy products packaging, etc., which often end up being waste, which is non-biodegradable. This plastic waste has good potential to be used in production of briquettes because it has a high heating value. Teak sawdust is also considered waste and usually not properly utilized. Nevertheless, it has a high heating value and sufficiently low level of volatile matter. Therefore, mixing HDPE plastic waste with biomass charcoal such as teak sawdust to make briquettes as an alternative domestic fuel is an interesting idea. The objective of this research was to make briquettes by mixing HDPE plastic waste and teak sawdust. The effects of two different natural adhesives (i.e. rice flour and corn flour) and the ratio of plastic waste and teak sawdust were investigated. The results of the experiment show that the best ratio of plastic waste and teak sawdust that produce the best quality of briquettes in this study was 50% : 50% and by using rice flour adhesive. The following are the results for this sample, the duration of fire starts to ignite was about 2.3 minutes; the duration of fire boils 125 mL of water was 12.8 minutes; and the duration of the briquettes burn to ashes was about 62 minutes.

Biological Rotation Age of Community Teak (Tectona grandis) Plantation Based on the Volume, Biomass, and Price Growth Curve Determined through the Analysis of Its Tree Ring Digitization

“…The carotenoid extractive substances in teak are beneficial for natural dyes for fabrics [87,88], hair dyes [89], dye-sensitized solar cells [90], and natural pigments for textiles, paints, plastics, foods, drugs, and cosmetics [91]. Villagers also exploited teak wood for energy resources like charcoal [92][93][94][95][96], firewood [97], bio-pellets [98], and bio-briquette [99,100]. Its versatile usage keeps the demand for teak high.…”
