ORGANIC COMPOSTING IN A BIN

                        Organic waste can be recycled at the household level to produce compost manure. Composting is the most simple and common method for recycling household organic waste. Composting is the process of optimizing the environment in the waste for microbial activity to decompose organic matter into valuable nutrients for the soil. Household composting involves the following three stages: waste preparation, degradation of waste and finishing of waste.

Waste Preparation

                 Waste needs to be sorted and prepared for rapid degradation. This includes the following steps:

                   Mix the waste to ensure that the carbon to nitrogen ratio (C:N) is close to 25:1. If the waste has too much carbon (normally brown waste such as dried leaves, saw dust) it should be mixed with waste that has high nitrogen content (also known as green waste such as kitchen waste). Kitchen waste only normally has a suitable C:N ratio for composting.

                    Chop the waste into small pieces. Large pieces of organic waste should be cut to small pieces to accelerate the composting process. Adjust the moisture content to about 50 per cent. A compost pile with 50% moisture should feel moist but water should not be dripping from it. Add a starter such as mature compost or effective microorganisms (EM) to speed up the composting process.

In-vessel composting

                  Compost can be made in bags or bins. Normally holes are made in the bin or bags to allow aeration. Compost bins can be made from 100 to 200 liter plastic bins or barrels. In order to allow proper aeration, the bin is normally divided into two sections with a grill separating the two sections. Organic waste is put into the top section and allowed to degrade and once the compost is prepared it is removed from the bottom section. Because of the natural draught created in the bin by the grill and the holes, frequent turning of the waste is not required in this method.

 

Why compost organic waste?

To manage the waste problem

                 We know that waste is a huge problem in many cities of developing countries and that organic waste represent almost 80% of the amount of waste. By composting this organic waste, we can help alleviate a large part of the waste management problem.

To produce a new useful and valuable product 

                 Knowing that chemical fertilizers are mining the soil and are not available for every potential client (they are often expensive and not always accessible), we can offer a more accessible product that is eco-friendly available at a stable price.

To reduce Greenhouse gas emissions


            In opposition to uncontrolled anaerobic fermentation of organic waste in landfills, compost and the composting process do not produce methane and therefore do not add any Greenhouse gas to the atmosphere. Methane has a global warming potential 24 times stronger than CO2.

To produce organic fertilizer

                     
The demand for organic food is increasing in Kathmandu valley, but organic farmers experiment a lack of fertilizer, as chemicals can’t be used in organic farming.

Journey form Training to Trainer : As Light of Hope Continues

                      Energy has been one of the basic requirement of human beings. The traditional use of fossil fuel is gradually shifting with advent of cleaner and greener technology. And change in people perception and consciousness about climate impacts, global warming and green house effects. RAN (Robotics Association Nepal) is one of Nepal’s best institutions trying to promote technology for generating holistic relation between machine and human.

                             The #LIGHTOFHOPE is audacious project initiated by RAN with agenda to connect rural livelihood to basic energy use like lighting and charging system. The process is to connect rural and earthquake affected area to primary energy use. The deprivation of energy & energy crunch is not only hampering economic activities but education of students. So #lightofhope aims to bring back hope to people to re-start life. Everything is broken but there stands only hope that things will get better. #LightofHope tires to embolden resilience, empathy and provide strength to return to normal living for Nepalese people who are beyond electric grid connection.

                                The Shree Nawalpur Secondary School was place for solar training and distribution. The place being in vicinity of Melamchi, still lacked proper road and electric connection. The event was already planned and well arranged by local partner YUWA Nepal. Primary task was to train ninety student, equip them for repair & maintenance, and distribute 5W solar system with light and charging system. We could see curious, energetic and bold ninety students, school authority, local experts being in school. We were really glad despite public holiday of Saturday people were kind enough to show up. The main objective was to give introduction about renewable energy, detail about solar system, component of solar system, repair & maintenance and about how solar can good business opportunity.

                                      Personally there is great difference in being with the crowd and handling the crowd. Being in training helped me to learn and nurture self. I was always obliged and felt privileged to get such opportunities. This was time to pay back or simply spread good vibes for others. I tried as much as being basic about facts and in mean time holistic. The major point I was careful not to let voids between by talks and student listening. The sessions was quite interactive, reaching student asking them and they asking back their queries. I was able to reach their psyche to some extent inspire them to lead from grass root. It was amazing to teach, hear, learn and share among students. The latter solar as business opportunities was carried out by Binod Pangeni. This session was especially designed to promote business opportunities that can or comes with solar technology. The main idea behind this was to encourage student to find solution within country and to remind them there are possibilities as well as potentialities developing country and making money in Nepal.

                                                    The journey to and fro Sindhupalchowk was full of fun. It was great conversation with fellow travelers local resident Aunt who rose my curiosity about place, her experience after earthquake, how grateful she was to have young people like us helping them, the hardship they have been through, hope & resilience they had despite their homes were completely turned down, her future dream to rebuilt house. Thanks to volunteers from Australia and Germany for being here selflessly to be part of re-construction. It was great to catch up with you guys. Oh! Driver dai, your story and reasoning and loud music system made us inexhaustible throughout travel. It simply helped us to be cheerful. Many many thanks to Bikash Gurung dai for providing wonderful opportunity to actually go to different part and shade some knowledge I had. It was great to reach people in local level and empower them. #LightofHope continues for adding hope for rural livelihood and re-construction after earthquake, shading light raising people’s aspiration.

Cheers.
