                           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.

Reflecting Back to Mentorship: Six months under Guidance

 

IMG_0051

                                The world is changing relatively faster than expected. The growing market of job is competitive and full of talent, where failing once means losing your job. The professional life is tough already, and its graph is increasing day by day. There are hundreds of professional coming out yearly with honed skills, talents and world life exposure. You cannot be left behind bewildering other progress.

                          Traditionally, the best way to learn was to find better master and be his/her apprentice. The evolving education system changed everything developing systematic progress of student to professional life. That does not mean need of mentorship/apprenticeship is bygone things. Still mentorship is considered best way to sharpening skills before you fail or simply learning by others failure. Your life is too short to fail on every step and learn from failure.

                           I got chance to be part of WWF Nepal The Generation Green Mentorship Program Batch 2 under mentor Anil Chitrakar (Social Entrepreneur). Along with me six others participated on this journey of six months. The main idea was to work one various creative project related to environment conservation, renewable energy use, 3R principle, wildlife conservation, and other several creative solutions. As we came from different background of study, it was hard for us to manage time for meeting and finalize our idea.

                    We were lacking confidence even we had ideas in mind, that’s where mentor guided us. He showed us light beyond tunnel and believed in our ideas. Every idea will work if you have courage to pursue them. These words still echo my ear and motivate me daily. Instead of focusing on single idea we tried cluster of idea as we had limited time of 6 months, so our ending point of idea would be starting point for upcoming groups.

                                 The main objective of our project was to establish a culture with a system of recycling, reusing and reducing of waste (food, plastic, paper, rubber & water). The basic task was to help in the conversion of low – end input waste into high value output. We helped to facilitate and bridge gap between waste utilizing institutions by innovative alternatives to appropriate potential market by designing ergonomically viable products as such:

1. Reusing Rubber Tire by Giving Aesthetic Values for Parks, Schools and Communal area.

                       The tire has been real issue as it cannot be recycled (economically at low scale in country like Nepal) or reduced but can only be re-used. We had re-used tire by integrating them into environment. They were used as flower pots for large plants, swings in garden or home, decoration by giving colors. We identified certain schools formed Eco-Clubs or youth clubs with whom we worked so that the sustainability of the project will not be an issue if local young people will take care of it.

2. Advocated use of recycled Plastic Bags into Ropes or Fibers for Agricultural Support:

                        We helped to recycle/reuse plastic bags as rope and it was provided as sample to farmers. This was done through the re-use of plastic bags by making ropes or fibers from them. The ropes can be used for making various green house, support for vegetable growth, building birdcage, temporary shelter and even making fences. The high strength plastic rope and fibers will come in handy for farmers for daily use.

3. Encouraging institutions for Creative use of Paper:

                     Paper is widely used for various purposes like printing records, brochures and leaflets. Reduce use of paper, printing on both sides of paper and promotion of e-communication was encouraged. On joint collaboration with Women’s Dream Multipurpose Ltd we made pencil out of sample old newspaper and encouraged such initiatives from other organizations.

 4. Rain Water Harvesting

                         Due to ongoing water crisis and larger number of family residing in small houses, it was very difficult to fulfill the water need in household use. So, being a researcher in watershed management, Mr. Laxman Shrestha had constructed a very simple yet a very effective way to use the rainwater. We conducted interview to share his noble idea for public use.

THE LESSONS

                         Indeed six months mentorship has been great journey of my life. We were able to work on ideas generated by us. We could see transformation on ourselves as well as we felt that our activities made some level of contribution and influence on society. We were lucky enough to travel various parts of Nepal. We made lifetime friends and created memory. Plus we learnt about professionalism, discipline, time management and respect of fellow team member.

                         Ratna Rajya Higher Secondary school, located in midst of new and old Baneshwor is changing its chaotic environment with plants planted on beautified tires. The school humming with students all over its complex, also housing many temples within premises was perfect location to show case our initiative, so that public could see and learn values of old tires. This was planned as per proposal submission and earlier site visits so we could increase our reach to greater mass.

                                  This was last chance to showcase our activities of old tire gardening and awareness initiative as men-tees and maiden within Kathmandu valley. We were always trying to do things differently. As we matured as professional in tire gardening, side wise we wanted to train youths form school so we requested four volunteers from school which principal mam accepted graciously. We managed to include four volunteers with equal male and female participation. The major task to include volunteers was to train, nurture and give them hands on learning so they will be able to implement similar concept in other location in future and will help in sustainability of project in school.

                                    The tires were carried from Balaju area to Baneshwor. The team lead for this project was done by Bina Kharel. The space constrained pushed us to reduce tire to twenty five. The event started with as usual by washing of tire, drying them up. In between we went for plants in nearby nursery. As we had restriction of mud so we had to purchase to fill old tire vase.

                                 Once tire were dried, they were painted by team member as well as volunteers. At later hours, the event was attended by Mr. Dipesh Gurung form ECCA Nepal. The event was co-ordinated and effectively handled by all team mates. We really took lead, connected dots and came as single one who were desperately trying to generate values out of waste. On parallel event with tire gardening Subina (Our Team Lead) gave well articulated presentation which was hugely praised by great round of applause. Finally it was a day well spent by all members.
