                           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.

Solar Training and Capacity Building : Power to the People

DSCN2369

                                    March 29, 2016 Before dawn of warm and fuzzy morning I woke with sharp shrill of mobile alarm at 5:00 am. As it was planned to meet at 5:45 am at Old Bus Park to move into another adventurous travel on off load leading to Dhunkharka, Kavre. The bus ride from Old bus park took us to Panauti via Bhaktapur, Sangha, Banepa. The real journey began from here accompanied by Mr. Subash Lamichane and Mr. Kancha Tamang. The 14km dusty, bumpy, narrow and scary road begun from Panauti steadily uphill climb in bus cramped with people, animals (chickens), kids crying, people yelling at each other. It was perfect like Hindi film melodrama at bus. Irony was that we were not able to get any seat through out two hours ride. Even within bus we had to wear mask and continuous shake up really made me tired. But internal motivation to go there and help people to sort things out, teach them, connect them to more reliable energy was continuously pushing me up.

                                        After travel of 2 hours we reached Dhunkharka. The bus stop was on top of hill to reach to our destination we had to go downhill and again uphill. The slow down hill walk began interacting with each other knowing about peculiar things about location. It was good to be back on hills among tress, clam and serene country side where nothing bothers you except cool breeze, birds chirp and perennial flow of river. I encountered various rural technology like water mill, hydraulic ramjet pump, fodder cutting machine, solar system. The very delicious meal was waiting for us, prepared from organic vegetables, grains crushed from water mills, cooked in improved cooking stove, rice grown in nearby fields. This was perfect amalgamation of technology with rural livelihood.

                       The training sessions began at 11:00 am. The 22 owners of solar system were present in upper floor of cowshed. It was great to see energy and enthusiasm in people. The training started with introduction of speakers and participants. The training was planned for 2 hours and following topics were discussed:

  • The initial session explained about what is renewable energy, Solar as renewable energy.

  • Participants were introduced about solar system and its components like Panel, Battery, Charge Controller and Load.

  • Installation do how and safety handling was demonstrated with system present on the location.

  • Various Procedure for Repair and Maintenance were provided.

  • Specific care handling, minor damage and quick repair locally was provided about battery, charge controller and loads.

  • Final solar power use calculation was done and how much load people can use with technology given to them was shown.

Training Outcomes

                          The people have been following malpractice about solar system handling. The solar panel were hung as photo frame in walls, no safety precaution were taken, people were brining in & out panels in rains, their perception was heat generated more power than light. About training accomplishment participants got chance to learn about each components of solar system. They are now able to assemble and dis-assemble the system on their own. The standard parameters like facing panels on south direction, keeping panels at 30/45 degrees, keeping battery far from heat source, use of loads according to power generation, sustainability of battery system, various light symbols and their meanings present on charge controller, minor repairs was provided. Overall looking after longevity of solar system with efficient use was provided.

                  After completion of training we visited two hydraulic pump operation at Chanaute and Ladkhu. We learned about bio-char preparation, its use.

                           The return was one of the most memorable journey of my life. The last seat of bus squeezed between a women with child and old grand pa. The lady by side was vomiting throughout journey while grand pa was drunk, mumbling and fumbling with words and directions. The smell from both side was killing me, as I sat contemplating about life. I endured situation, just invigorated into circumstance.

                                              This was one of my life awakening journey. What surprised me was humbleness and subtlety of people. Obviously they are cutoff from mainstream media attention still they are happy to be living there. There are numerous challenges but somehow they have managed to be living well. I hope to see better road access, sustainable clean energy supply, educational facilities, better health facilities and access to ICT be within their reach. The natural serenity shall not be disturbed, only right technology along with nature can develop Dhunkharkha.

Harbinger of Old Tire Re-use Project and Waste Value Generation

IMG_0648

Shree Jana Jyoti Secondary School, the model school typically located in mid-way from Sangha an Banepa with curious student and helpful faculties. This was first school where we wanted to implement our old tire gardening concept. ECCA facilitated and provided connection to school authority from where we took the lead, we first visited and inspected the site. We got very warm and positive response from school administration which further motivated us in our cause.

Initially we were planning to look after nearby workshop for old tires but could not materilize as size we were looking for gardening had to be of medium one. As school is located in highway so there was availiability of only large tires. The transportation of tire was a bit hectic and costly, as we had to take it from Kathmandu. But we managed to take it at reasonable rate despite acute fuel shortage.

Everything was well planned and co-ordinated beforehand. We departed at 6:30 am from Balaju area, picked up all members and volunteers from Industrial Engineering Student Society. (Bishnu Parajuli, Pradip Bista, Kshitz ). We reached school around 8:00 am in school premises. The energy and enthusiam kept us warm despite severe cold. We started washing tires, as water tank was on roof of school building it was hard to blow through mouth to pipe it out.(Nepali way) It took nearly a hour for washing tires, which were neat and clean by then.

This was challenge for all of us, as we really wanted to make whole this event neat and clean. After breakfast at nearby Cafe (which was amazing Bread Toast with Kuwa followed by Coffee), we inspected sites for placing tires. The stacked tires were supposed to placed around compound of school where as single tire was to be placed on roof top as roof top gardening.

The tires were artistically painted and dried up in sun. The stacked tire were tied up together by using gavinized iron wires, so that would not allow movement of upper tires with respect to lower one. We, along with student mixed up soil, ash, organic manure to make fillings for tire vase. As there was nursurey nearby owned by one of committee member of school, he provided perinial, seasonal and indoor plants at subsized rate.

 

The athestically appealing painted tires were placed in various locations like in the rooftops, main gate ways, pheriphery of school. The tire garden not only generated value out of old tires but also pioneered/innovated re-purposing of same generating economic as well as environmnetal values. The process helped us to concrete ideas, and provided opportunity for learning and sharing. The members co-ordinated well with volunteer. In meantime volunteers reflected true and self less volunteerism for generating meaningful result.

About Volunteers

Three enthusiatic and hard working volunteer from industrial engineering society participated in the event. They were 2nd year student from Institute of Engineering, Thapathali Campus. We were so grateful to have them in the team.

Members Learning

Me, Sneha and Sunwi (TGG Mentees Under Mentorship of Anil Chitrakar) co-ordinated all activities. It was fun filled, equally challenging task with arduous manual labor. We learned about team co-ordination, role distribution, to give order & take orders, technicality involved in plantation like mixing of organic manure, ash, mud & information about various plant species, and their requirement for growth.

Benefits and Outcome

  • Positive vibes among school teachers, staffs and students with some different approach of gardening at school
  • Hands on learning for student and student participation in program boosted student morale for consversation and sustainability
  • School authority were glad to introduce unique gardening in school, new in the concept eqaully a logical solution to illogical problem
  • Management, Re-purposing of 4o tires somewhat helped in Carbon management in low scale
  • Plantation of flowers, plants increased greenery and environmental promotion to some extent
  • Inception and pioneering of tire gardening, begining of new era of approach for reuse, repurposing of old tires in Nepal
