5. PESTICIDE RESIDUE REMOVAL: The absorption qualities of charcoal powder, especially activated charcoal, helps in neutralizing the harmful effect of pesticides. Mix 500 grams of charcoal powder to 1 gallon of water (1 gallon is litres). Spray or sprinkle this over the pesticide treated plants. This is very useful in edible gardening.

While efforts are underway, critics say not enough is being done to meet Malaysia's ambitious decarbonisation plan. After all, coal, which is the biggest polluter of all fossil fuels, is the largest source of electricity in the country. The last coalfired power plant is only expected to retire in 2044, over two decades away.

What is coal used for? Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity.

Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of impurities (coal grade).

Charcoal is stable and durable. It is capable of persisting in the soil for a very long time. Of course how long may depend on the type of charcoal, conditions, soil etc. but it is no doubt capable at times of persisting for millennia. While some of the minerals in ashes may be persistent, ash is essentially a very short term fertilizer.
