                           Ever wondered about the tires which are no longer roadworthy after they are used? They are stockpiled, dumped in landfills, or just thrown away on roadsides. This linear product use approach results in a massive waste.

              Tires, whether it is electric, solar powered, gasoline, or hydrogen fueled vehicle, are indispensable components for the transportation industry. Scrap tires have potential to harm local environments and negatively affect human health. The most common problems associated with waste tires are open air fires and the creation of breeding ground for rodents and mosquitoes. It’s bad but it’s a fact. According to The Freedonia Group Report it is estimated that the world demand for tires is forecast to rise 4.7 percent per year through 2015 to 3.3 billion units, approximately same amount of tires are disposed of every year and almost 20% of them are illegally dumped in landfills, or just thrown away on roadsides.

              Is this the end of the story? No, a these approaches can ultimately lead towards right environmental choice and would also make good financial sense.

Circular Economy

              The alternative to the growing waste concerns is to develop a circular economy which goes much further than recycling and there is a strong business case for development. Building recycling industries to recover, recycle and process the waste tires – with the focus on the reduce and reuse principles, unemployed people can find gainful employment, SMEs can be developed and, the environmental disaster that waste tires represent can be economically and effectively addressed. Analysis by McKinsey estimates that shifting in this direction of circular economy model could add $1-trillion to the global economy by 2025 and create 100 000 new jobs within the next five years. It’s worth it!

Energy

              A normal used passenger car tire weighs 7.2 kg; it contains at least 238 MJ of thermal energy, which can be useful in some dedicated facilities. In thermoelectric plants, tires are fed into the hearth without any pre-treatment or slicing. This process is an economically viable alternative for used tires that cannot be effectively retreaded, generating a large amount of by-products. Each ton of input (as tires) generates 287 kg of solid residue made of zinc oxide, ferrous slag and gypsum, each with a well-defined market. The use of old tires as fuel has the advantage that it does not generate any waste beyond what is usually generated by a standard cement production process. Sliced tires can be fed into the kiln with the other raw materials. The energy in the rubber provides the heat while the combustion residues are incorporated in the cement without compromising the product’s quality. The ferrous material from the steel wire partially substitutes the large quantities of iron ore used in cement production. Several fuels are used in a cement plants including coal, natural gas and oil. The rubber may provide roughly 20% of the heat required in the kiln, generally at a lower cost than the other fuels. The high temperature of combustion, around 1400°C, under appropriate supply of oxygen, ensures complete burnout of the organic material.

Construction Applications

              Rubberized asphalt is an alternative to traditional paving material that combines the strength and versatility of asphalt and the longevity and flexibility of recycled rubber. Derived from scrap tires, the material is said to be longer lasting, safer, less costly and friendlier to the environment than traditional paving materials.

              Scrap tires can be processed into ground rubber to modify asphalt thereby creating rubberized asphalt and rubber asphalt concrete. Asphalt companies buy large quantities of shredded rubber crumbs to mix with their hot melt asphalt to make pavements cheaper. Other road construction companies purchase large quantities of medium sized shredder tires to use in road beds for minimizing vibrations and for highway sound barriers. Rubberized asphalt is not just sustainable, but actually better than the traditional alternative, better in every way.

              Old tires can be used in barriers such as collision reduction, erosion control, rainwater runoff, wave action that protects piers and marshes. With a blend of art and engineering, the civil engineering applications of waste tires are emerging.

Re-Purpose

              We can use old tires in child’s play areas. They’re great for setting up an obstacle course or making a sandbox or a tire swing. Tire mulch is also sold as padding for children’s playground. We can make soles for shoes or even entire pairs of flip-flops. We can make livestock feeders or pet house out of old tires. Used tires can be transformed into furniture with a little pie of skill and imagination. Since tires are black and they retain the heat from the sun easily, you can use them in your garden for growing your plants earlier. Basically, you can grow plants and veggies in tires earlier than in the ground. This trick works great with those species that require more warmth. You can make an outdoor storage bin using old tires secured together with some plywood and painted in your favorite color. Old tires can be transformed into a cool coffee table or other cool pieces of furniture. Just dive, there’s a world of thing you can do. Re- think!              

              It has been years since we dumped the opportunities for business through valuation of the waste. But, an era is evolving to turn the wastes in every bin into something really spectacular and create value. It is a new shift in the resource management approach, a transition to the unexplored territory and it provides battle against the traditional inertia of waste management. This is the way towards sustainable economies and eco-innovation, and can drive development across the board. This benefits all of us.

Himalaya & Sun

 4

                     This is story of every household of Nepal’s Himalayan region when you climb above 3000 m altitude. Most of household including hotels, lodges, restaurant are equipped with solar panel turned into direction of sun. Due to lack of transmission line to transmit hydro power generated electricity, solar power is only viable source of power for people living here. People are cent percent dependent on solar power to charge mobile battery, lighting small portion of house and watching selected television program. Although it is costly and provide minimum amount of power to run daily life still it is boon for them. There is no clue for survey of transmission line and searching alternative power.

                     So solar technology is not only environment friendly but it has been only hope of people to lighten their house. Thus government should be able to provide subsidy and encourage use of solar power. This is not only be Eco-friendly but also save forest from deforestation. If you want to see real life use of solar technology pack your bag and move toward Himalayas.

Swarga Dwari: The place where Spirituality Meets Technology

                      Nepal, country of mountains and holy places, boast on natural beauty and wilderness. The holy shrine of Swarga Dwari lies in western Nepal of Pyuthan district. It is one of popular destination for hindu devotees as one can feel in temple premises. Hindu devotees flung as far as from India to get blessing from shrine.

                 The holiness of temple traces back to discovery of ancient hawan area and related puja materials. The young shepherd traveling from far western part happens to be resting on bajh(a 100 year old tree located nearby) saw a vision that place is blessed by gods and once was place for worship of god. He asked fellow herders to dig around premises to discover ancient leftovers of hawans, vessels and other holy materials. It is believed he had supernatural power of healing, spent most of time in meditation, started school for teaching holy scripts, procured land for cultivation so temple attendees and follower will never be in scarcity for food. He is regarded as very holy person, you can see his statue inside temple.

                         The other story is: this was last place visited by Pandavas from Mahabharat before moving to heaven. The Pandavas were thirsty and Arjuna took a bow, aimed in ground to withdraw sprout of water to quench thirst. Still the sprout known as Kunda is visible downhill from temple. As Pandavas spend one night here before departing to Heaven (Swarga), often devotees spend one night here.

                          The Swarga Dwari Trust arranges food and residence for devotees in various Dharmashala in periphery of temple. The per bed cost is Rs. 30 and per plate food is Rs.100. The residence hall are primitive Nepalese mud house but decent one with mattress, blankets. It is wise to carry your own bedsheets. The food is normal vegetarian which includes rice, lentil and vegetables popularly know as “gods food”.

Major Attraction

Hawan Area with Eternal Lamp

              There is 24 hours, 365 days continuous hawan. The nearby was eternal lamp, I could not see lamp but was given through instruction how it was brought by pathak (priest are called so here). It is scared place where you give ghee, rice, oil and charu (mix of various grains especially made for hawan). No photos allowed here.

Main Temple

                This is place where you worship lord Shiva which is built upon grave of guru, founder of temple. The initial worship on this temple follows with multiple temple presence on the premises.

Bajh Tree

              The tree is supposed to be more than 100 years old. The importance, holiness trace back to resting place of guru who discovered this area so holds greater significance as you can see vermillion smeared all around.

Cowshed

              There are more than 250 cows reared in cowshed. The cows are supposed to be very holy and devotees throng to feed them flours (especially Satu) and salt. The excessive feeding of salt caused death of many cow so its forbidden to give salts these day. You can just deposit it in near by specified place.

Cave (Gufa)

            The cave is place where guru use to mediate. Supposedly it was place where Pandavas took shelter before going to heaven. It is naturally built place around 20 mintues walk around the hill.

School (Pathsala for holy teachings)

             The pathsala teaches student holy scriptures for continuity of tradition. The young boys keep chanting mantras, sloks, hyms, vajans from early morning. Usually they teach 3-4 years for student with compulsory 1 year practice as priest in temple.

Water Sprouts (Kunda)

          The Kunda lies 15minutes downhill walk. The water (jal) is brought from kunda for offering to god by pathak on barefeet without being touched by anyone. The water sprouts is believed to come into existence by piercing of arrow via bow by Arjuna from Mahabharat.

Bhairavi Temple

          The 10 minutes uphill walk will lead to Bhairavi temple. From here you can have great view of surrounding area.

Technology

         The temple houses large solar power station providing and supplementing electricity for temple premises. The solar street lamp provides durable light throughout night. The solar lightening has been helping to keep life in night as main stream supply is so infrequent. The night life felt so lively with flashing white light around premises.

             There is large bio-gas plant which provides cooking fuel for people’s kitchen. The cow poop is used for making bio-gas which is very helpful for conservation of local forest and keeping far from LPGs. The bio-gas is enough sometime supplemented by firewoods for cooking.

            The temple is located in top of hill. It is quite challenging to fetch water for people. Although pumping is done by electric motor from downhill. We can still see rain water harvesting done around top of official building of temple.

        This is great gesture of adaption of technology for facilitating devotees. Thus Swarga Dwari is holy place with blend of spirituality with technology. This can be benchmark for other holy shrines to replicate in them.

MYTH’s

  1. It is believed once temple ran out of ghee for hawan. The guru asked his follower to go to ganga (Madi River) and burrow few tin cans of ghee. The follower being surprised went to river, drew few tin can of water and came to temple. The guru asked them to pour them hawan. The follower despite being reluctant to pour, poured on gurus command, to surprise it turned to be ghee. Again after couple of months when temple had surplus ghee, guru asked them to pay back ghee to ganga. When followers poured back ghee in ganga to their surprise it turned to be water.

  2. The guru was having discussion with his follower. The very eccentric bird yellow in color came from Northern side, guru spoke in birds language with birds. The bird flew back, curiously follower asked what he had spoken with bird. The guru said that his time on earth has come to end, the bird came to notify him. After few days guru became sick, called his follower gave them all responsibilities. There was some bright yellow spark glowing out of guru which rose high above temple, and rushed into northern himalayas. The guru was found to be dead by then.

  3. There was hunter who injured deer. The deer entered temple for sanctuary. The hunter asked guru to return back deer to him. The guru said “ I cannot offer you deer as it came for sanctuary in my asharm, ask anything other I will give you”. The hunter being adamant on his claim of deer and misbehaving, manhandling guru. The furious guru gave curse(srap) for hunter that he has to die of some disease. As matter of fact that happened.

About Guru

                       The couple in some far western Nepal did not have any son or daughter. They worshipped god and were believed to be blessed by god. That they will have son who will be actual incarnation of God. The mother gave birth to son, who was glowing with light since childhood. On 6th day when mother ate meat, son refused to suck milk from mother. Since child guru was supposed to be holy. Even it is believed that we could see universe inside the mouth of Guru.
