Today, around 15-20 billion pencils are manufactured globally every year. to make these pencils numerous trees are cut, which harm the ecological balance. currently 20 acres of rainforest and 40 species of animals are killed every minute just to make pencils. innovated in 1560, pencil is one of the design which has hardly changed fundamentally over the period of time. even, numerous other technical designs of writing instruments could not replace pencils because of its simple and complete design. but, it also consume our precious forest work to visible adverse effects. we have identified a noxious weed “lantana”, abundant in south asia, southern africa and australia which can replace the red wood used in pencil without affecting its remarkable complete design. we also have developed a process to straighten the curved lantana sticks. moreover, the pencils made of lantana is comparatively lighter and therefore comfortable to use for kids. the design is also optimized for reducing unused graphite lead. lantana weed grows fast enough to fulfill the growing demands and that too without any human efforts. it is estimated that, four sq. ft. in open field can generate wood for 15-20 pencils every 3-3/2 months. an optimized collection system if developed, can optimize the cost of collection of lantana stick along with generating employment for local workforce. to attain the attention of the user to this new pencil, its aesthetics are kept as close as possible to the existing one. this way it will be easy to place our pencil in the market without changing buying behavior of the existing pencil.
