The Effectiveness of Low Carbon Waste Management Efforts in West Papua

The Effectiveness of Low Carbon Waste Management Efforts in West Papua

Solid waste is one of the leading causes of greenhouse gas emissions (GHG). With the significant increase in the population of West Papua per year, the production of solid waste and emissions are also increasing. For this reason, efforts to treat waste optimally are the best way to deal with waste. Here is some information about low carbon waste management in detail.

Waste Production

Garbage is a by-product of human activities and natural processes: household waste, emissions, and particular wastes. When accumulated, waste has massive environmental damage. In addition, waste also causes problems related to health. However, the characteristics of the waste vary, depending on the components of the trash.

Some forms of solid waste from human and animal activities are concrete and considered useless. Solid waste generally produces greenhouse gas emissions in the form of CO2 and CH4 gasses. At the same time, the movement of burning waste has CO2 gas, while open disposal at the landfill causes the accumulation of waste that produces CH4 gas.

These gasses are included in the greenhouse gasses for significant global warming losses. In this case, waste management activities contribute about 4% of greenhouse gasses. However, appropriate waste management reduces greenhouse gas emissions, odors, and emissions. Thus, preserving the local environment with waste management is an important activity.

West Papua Province is located in the eastern part of Indonesia, whose population increases from year to year. The population growth rate of 2.65% per year has the consequence of increasing the volume of waste, which can seriously impact the environment. If not properly managed, waste harms greenhouse gasses in the atmosphere.

Garbage Problem

The generation of solid waste at the city level grows faster in line with population growth and increased living standards. It is also influenced by the increasing flow of urbanization, economy, and life growth. Based on data on the composition of waste in Papua, 70% of the waste comes mostly from food scraps, while the remaining 20% ​​and 10% come from wood and paper.

Most of the solid waste generated in Papua has not been appropriately managed. Households, industrial and commercial sectors dispose of their solid waste into the trash without any separation. As a result, the waste is the responsibility of local government agencies to open landfills for final disposal. Generally, the waste in West Papua has not been processed.

Efforts to Minimize Waste

Seeing the facts above, awareness of waste management in Papua is low. Lack of knowledge and minimal skills in waste management is a significant concern in empowering local communities. On the other hand, the provincial government has provided trash cans in the area. Unfortunately, there is no separate bin for organic and inorganic waste.

Therefore, there is a need for proper solid waste management because every waste impacts greenhouse gasses, emissions, and pollutants. Alternative 3R methods (reduce, reuse, recycle) are the primary efforts to reduce the volume of garbage. In addition, implementing strict laws in waste management helps improve the quality of environmental sustainability.

As a result, these efforts can reduce carbon gas emissions into the surrounding environment. However, data collection is an obstacle in building a good waste management system. Most of the waste is thrown away because of the vast amount of waste produced per day from every household and another sector in West Papua.

Therefore, several approaches to estimating total waste are essential. The government involves the population and gross domestic product to calculate the number of emissions produced more efficiently. This calculation will provide significant results for tackling the problem of waste and pollutant results from large waste production.

Several studies have even estimated waste production using dynamic models. However, the results are still less accurate because the waste increases each year significantly. The business as usual (BAU) method is the primary method to get the best scenario for low carbon emissions from waste. In addition, this model is proposed to reduce GHG emissions from waste.

The Business As Usual (BAU) model provides an interlinked relationship between total population, waste, and landfill capacity. These factors are significant to represent the growth rate of waste every year. This model becomes the basis for designing scenarios to achieve the target of low emissions from waste.

Proposed Scenario Overcoming Garbage

Using BAU from solid waste generates substantial emissions. This numeral waste will persist in rising in the years to come. Therefore, there are many new scenarios to intervene in the trash to meet emission targets from the garbage. Also, the government is proposing certain landfill expansion areas to address emissions and waste.

Mitigation strategies in West Papua improve solid waste management to reduce greenhouse gas emissions from a stable waste sector. Incineration is the right way to minimize the effects of solid waste. Since food waste consists of solid waste in Papua, burning waste reduces energy and increases combustion efficiency.

Furthermore, more reliable recycling technologies such as anaerobic digestion of food waste are essential to produce valuable creations. It has become one of the most effective technologies for dealing with waste. In addition, the application of 3R (Reduce, Reuse, and Recycle) solid waste can be an option in a sustainable waste management strategy. It has a significant socioeconomic impact on climate change.
