From this research, the writer draws three main conclusions: 1) Briquettes produced from sawdust are not inferior to coal, 2) Sawdust can replace coal as it becomes more scarce, and 3) Using sawdust to make briquettes is more effective than other materials since sawdust is easily obtained and reduces environmental waste. The writer also provides two suggestions: 1) Readers should more utilize sawdust waste by making briquettes as a coal replacement, and 2) Users could create new innovations by making briquettes from other wastes like dry leaves and rubber seeds.
