Sacrificial waste: Environmental impact and to-do
MD. MIZANUR RAHMAN : – The holy Eid-ul-Azha is going to be celebrated in the midst of the epidemic of the corona virus. With that have the outbreak of dengu. As the lockdown has eased since july15, 2021, the tendency for people to go out has also increased as a massive rate. Anyway, according to the Ministry of Fisheries and Animal Resources, the number of animals are ready to be sacrificed on Eid-ul-Azha in 2021 is about 1 crore 1.8 millions in our country. Sacrifice arrangements are being organized across the country that is usually in two episodes; One is the market for buying and selling the sacrificial animal, the other is the sacrificial animal slaughtered and processed and distributed according to the law. Apart from some online animal market, there are many sacrificial animal markets in different places across the country. Unhealthy and polluted environments for hay, grass, husk, bran, water supply and use, dung, urine as well as human movement, monsoon season and mismanagement are naturally created in those animal markets.
Sacrifical animals are slaughtered everywhere in the parking areas of building, courtyards and front streets of the capital or urban areas. Even in villages, sacrificial animals are slaughtered unplanned. These places are probably not disinfected. Unconscious, unplanned and mismanagementically animal slaughter results in the spread of blood, intestinal debris, waste litter, rotting odors, polluting the environment and becoming a breeding ground for mosquitoes and flies-that’s posing a serious threat to the human body and the environment. The production of pathogenic micro-organisms and greenhouse gases from animal wastes (such as methane, carbon dioxide, nitrous oxide, ozone ete) result in various viras and bacterial diseases, eye and respiratory damage, anorexia, bone problems, cancer, heart disease, impaired development of baby’s intelligence and loss of life in pregnant women. Acid rain can also occur. Animal dung can enter groundwater and contaminate water. Methane produced from animal waste is also responsible for global warming and people die as a result of pollution. According to 2015 World Bank statistic, 28% of the deaths in Bangladesh each year are due to environmental pollution-related illnesses, and 16% of such deaths worldwide. Moreover, the impact of waste on the climate is also a matter of great concern.
Therefore, the concerned authorities have to take appropriate steps to prevent environmental pollution by sacrificial waste and besides, some initiatives have to be taken at ward, mahalla or private level. Waste needs to be recycled. Some action may be taken which is realistic and environmentally friendly- that’s are below.
1. Care should be taken to ensure that the place of sacrifice is not in a densely populated area but in a relatively empty place. And that the place and the auxiliary equipment should be cleaned with a disinfectant.
2. Waste removal or recycling will be easier and faster if the sacrifice is made in a specific place with a neighborhood or mahalla without sacrificing in a single place in any city or village.
3. After slaughtering the animal, the blood should be washed with water or cleaner and sprinkled with bleaching so that the odor does not spread or the mosquitoes do not lay eggs in the frozen water. If possible, especially in rural areas, after slaughtering the animal, the blood should be collected in a small ditch, but the soil should buried. After a few days it will turn into blood fertilizer-which acts like urea fertilizer.
4. After sacrificing the animal, the leather should be removed by a skilled person and the blood and fat should be removed from the leather quickly. The leather can be preserved by washing the leather with clean water and drying it in the sun in open. After cleansing, the leather can be preserved applying salt by understanding the leather type. The leather can also be stored in the cold storage. A lot of foreign currency can be earned by exporting these leather. Glue is made from leather for various purpose and is used to make clothes, coats, pants, shoes, sandals, belts, wallets, bag, drums, musical instruments, expensive book covers, footballs, basketballs, racquets etc- a lot of money can be earned through exports.
5. Slaughter animal’s dung, entrails and leftovers should be packed in eco-friendly bags and dumped at designated places or in dustbins. Or if you put it in a hole in the ground, you can make high quality organic manure, especially through compost. Which can be used the flower or small tree’s on the roof and varanda of the house, garden and which is best used on agricultural land. However, when digging holes in urban areas, care must be taken not to damage gas, electricity, telephone, net, water lines.
6. The blood can be dried and powdered to make protrin-rich for chicken or bird food. Bone meal can be made by grinding animal bones through machines to feed chickens and cows. The entrails can also be used as a delicacy in fish dishes.
7. One of the sources of fuel and energy is biogasplants, one of the ways to utilize animal waste in this biogasplant and thereby reduce the harmful effects of antibiotics.
8. At the end of all the waste cleaning and sacrificial work, the blood-stained place or road should be washed with water or cleaner and sprinkled with bleaching. At last, everyone should wash their hands and body thoroughly with soapy water, soap or other disinfectant.
9. It is possible to make very high quality ‘sausages’ from the blood of sacrificial animals which is quite popular in many developed countries. It is also possible to earn foreign currency.
On the otherside, countries like Sweden, Norway are converting to other materials that can be used for proper waste management. In this case, they are also importing waste from other countries. So, we have to remember, today’s waste is tomorrow’s wealth and waste is cash. For this we need timely decision, planning, management and implementation. But it is a matter of great regret and realization that the inadequacy of modern and safe waste disposal or recycling management is one of the environmental problems of Bangladesh. To get out of here, the role of the government and the appropriate authorities is undeniable, in converting-the environment, information technology, agriculture, animal and microbiology researchers and scientists into environmentally friendly waste management through modern and safe removal management and recycling.
