The prices of natural gas and electricity are still rising, so it is advisable to find new sources of energy for heating houses and apartments. Trimmed tree branches, cut weeds and paper no longer suitable for recycling are landfilled or burned uselessly in the fields. This produces quantities of methane and carbon dioxide, which cause the greenhouse effect and global warming. You can use this waste in a simple way make briquettes suitable for heating. The material is split, the chips are compressed into briquettes and after drying are suitable for heating. This can save a significant amount of natural gas and electricity. Figure 9 - splitter and chips, figure 8 - briquette.
