Compost Production in the Seyhan Municipality
City/Region : Seyhan Municipality , Turkey

Seyhan Municipality aims to recycle farmers market and garden waste into compost and bring it back to soil as a useful and valuable organic fertilizer thanks to natural processes. With the compost production, it is aimed to promote both soil improvement and organic fertilizer use and recycling. By producing compost, Seyhan Municipality aims to evaluate organic wastes, improve the structure and aeration of soil, neutralize toxins, provide nutrients when plants need it, strengthen the plant by accelerating growth.It will been contribute to the conservation of biodiversity, climate change, enviromental pollution thanks to compost production.

Context
Compost-Seyhan Municipality- Mayor

The concept of “green growth” come into prominence with the search for a new growth model that started on a global scale in order to achieve sustainable development goals. Within the framework of this concept, it is possible to protect both the environment and increase competitiveness with clean production and eco-efficiency in the production sectors, ecological potential is evaluated in environmentally sensitive sectors such as agriculture and tourism, and it is emphasized that cities can be more environmentally friendly and economically effective with new regulations and investments. Within this scope, priority is given to the efforts to prevent pollution, conservation of biological diversity and natural resources and its sustainable use. Turkey has the potential to transform environmental challenges into opportunities with environmental decisions and projects. Seyhan Municipality will contribute to improve the soil with climate change, pollution, biodiversity and environmental status of Turkey's development by converting agricultural wastes into compost.

In Action

Seyhan Municipality aims to recycle farmers market and garden waste into compost and bring it back to soil as useful and valuable organic fertilizer thanks to natural processes. Wrong disinfect and excessive use of chemical fertilizers pose a threat to nature and groundwater resources, making it difficult to take products by inefficient soil. 

Organic matter rate in wastes is high in turkey, which is developing country. According to studies, a total of 698,430.78 tons / year municipal waste was disposed in 15 districts in Adana in 2018. The average amount of solid waste collected in Seyhan Municipality in Seyhan district of Adana is 773.32 tons / day in summer and 747.99 tons / day in winter. Seyhan Municipality Cleaning Affairs Directorate, responsible for collecting and transporting wastes in Seyhan, which has a population of 764,714, has spent a 32.5 million TL in 2012. This expense corresponds to 18.5% of the total budget of the municipality, in other words, a budget close to 1 in 5 of revenues is reserved only for environmental services.According to Municipal Law No. 5393 and Metropolitan Municipality Law No. 5216, it is the responsibility of the district municipalities to collect solid waste and transport it to disposal facilities or transfer stations. Therefore, Seyhan Municipality generates urban wastes of organic origin every day in the Seyhan district of Adana and aims to be used for multi-purpose purposes, especially for the improvement of agriculture and forest areas by transforming these wastes into compost.People will be able to grow healthy fruit and vegetables with their organic fertilizers on the balconies of their homes. Another benefit of compost is that it provides the opportunity to function microscopic organisms and bacteria. In this way, less disease and insects are seen in the growing plants. This will also mean that you use less pesticides.Compost not only helps combat global climate change, it also prevents leakage in landfills, saves land from being used for solid waste storage and provides green collar employment. For successful composting, the waste to be used in the process is of great importance in terms of the nutrients it contains. Therefore, agricultural waste will be used in the Seyhan region. 30 stainless wire cages with a length of 1.5 meters will be used for compost production. Production is targeted by digging pits with a distance of 1 meter inbetween.Compost generally shows values ​​close to or above farm fertilizer.

Results

We take the average values, in field applications, it can be given around 10 tons per decare and this amount corresponds to 150-200 kg of compound fertilizer. Nowadays the use of soilless or partial soil development environments has become quite common, in vegetable, ornamental plants, nursery and even dwarf fruit growing. Economical, environmentally friendly and yield enhancing compost is another aspect that should be taken into consideration as an alternative or support material for many development environments. The parameters affecting the compost formation process speed and compost quality are particle size, C / N ratio, moisture content, mixing, temperature, ventilation and pH. Compost can be used as a soil conditioner due to its features such as containing essential plant nutrients like N, P and K, also micro plant nutrients such as Cu, Fe and Zn along with providing better soil aeration and better water holding capacity.Due to the advancement of technology and the increase in the population and consequently consumption, the amount of solid waste that is released daily per capita has increased, especially in big cities. The use of wastes in composting is of great importance both in terms of contributing to the economy and preventing environmental pollution. Compost; It also has a commercial value that can be sold under names such as organic fertilizers, soil improvers and growing media. All these benefits that can be obtained with compost can only be achieved through a controlled and successful composting process.It turns into compost that can be used as fertilizer depending on the humidity and air temperature in bio-wastes.It is understood that we should support composting and recycling. In this case, the carbon footprint will be reduced. The soil enriched with compost retains more water. This feature, which is very important for dry summers, will enable natural resources to gain.

Impact

Approximately 3800-4000 tons of domestic waste is generated daily in Adana and Mersin. Approximately 2500 tons of this waste is disposed at licensed facilities in Adana and Mersin. However, the remaining 1500 tons of waste is left to the nature by uncontrolled disposal of waste. In other words, 540 thousand tons of urban waste accumulates in open land in unhealthy conditions every year. This poses great threat to human health and nature. In terms of economy, the opportunity cost of storing wastes is quite high, considering that an installed power of over 10 MW is produced from 1500 tons of domestic waste per day in Adana and that 300 tons of uncontrolled disposal of waste can be recycled per day. The Ministry of Environment and Urbanization aims to close uncontrolled disposal of waste areas by 2023 in the Climate Change Action Plan. On average, 2,000 tons of domestic solid waste collected from residential and commercial institutions is brought to Adana Metropolitan Municipality Integrated Solid Waste Disposal Facility by 15 district municipalities of Adana. Approximately 1 in 3 of domestic waste can be composted, so it can be saved from being garbage. In this way, the density and methane emissions in the waste sites are reduced and you increase your air quality. We may have saved valuable material that you left out of your home every day from being garbage.According to the researches, human population is expected to reach 9 billion by 2050. Increasing in the human population will reveal the incredible loss of overconsumption, climate change, enviromental pollution and biodiversity.Therefore, we need to take measures to slow or stop biodiversity decline.Organic wastes do not contain methane. Methane is released only when organic waste is placed in anaerobic environment.Biowastes goingto landfills and waste storage lead to emergence of methane gas.

Challenges and lessons learned

When soluble biological organic wastes are sent to solid waste landfills, as result of natural degradation, it releases methane, a large amount of greenhouse gases, which will lead to soil and groundwater pollution.Seyhan Municipality will contribute to improve the soil with climate change, pollution, biodiversity and environmental status of Turkey's development by converting agricultural wastes into compost.the probability of erosion is reduced. When used in sufficient quantities, compost has a positive effect on soil structure both in the short and long term. It can increase drought resistance and provide more efficient water use.Compost will be very useful in our region.
