1、Evaluation of Effective Microorganisms on home scale organic waste

EM was reported to reduce odour, increase the decomposition rate and producing compost with higher nutrient contents (Jusoh et al., 2013). Another study stated that the use of EM was not necessary to ensure good composting (Nair and Okamitsu, 2010). This shows diverse opinion about the effectiveness of EM for composting.

Result: EM has a great potential to be applied on food waste composting as it can accelerate the composting process and reduce odor during the decomposition of organic material.

3、Environmental applications of Effective Microorganisms: a review of

When it comes to the protection of the environment, EM helps in waste deodorization, eutrophication control, and wastewater. Investigation on EM use in water quality restoration, wastewater treatment, the treatment of sludge, and composting has been undertaken by researchers.

Investigation on Preparation, Characterization and Application of

EM can ensure high quality compost as the microbial inoculant increases the production of aerobic bacteria and increases the composting speed. The main species involved in EM include lactic acid bacteria, photosynthetic bacteria, yeasts, actinomycetes and fermenting fungi (Diver 2001).

Microbial Community in the Composting Process and Its Positive Impact

While numerous studies have focused on the benefits of plant cultivation, fewer studies have focused on the benefits for soil microbiota. The objective of this review was to elucidate the role of the microbiota in the composting process and its impact on soil microorganisms in agriculture.

Result: EM has a great potential to be applied on food waste composting as it can accelerate the composting process and reduce odor during the decomposition of organic material. Conclusion: EM has a great potential to be used in accelerating the composting process and increased nutrient in compost.

Microbes as vital additives for solid waste composting

An EM inoculated compost attains better compost quality and maturity in less process time period. These EM's can be isolated from variety of conventional sources such as soil, waste material or leachate and applied to the process at different stages (initial, mid or last).

Preparation of Effective Microorganisms Based Compost Using Some

to reduce the amount of organic waste through recycling and the production of soil fertilizers and conditioners. Compost is primarily used as a soil conditioner and not as much as a fertilizer because it contains a high organic content (90-95%) but generally low concentrations of nitro.

The use of EM (Effective Microorganisms) bacteria in composting is a common practice, but it is neither the only nor an essential option. EM bacteria, short for "Enhanced Microbial Fermentation," refer to a group of highly active complex microbial agents. They can decompose organic matter, improve soil fertility, and enhance environmental quality. Adding EM bacteria to compost can accelerate the decomposition of organic matter, improving the efficiency and quality of composting. whether to use EM bacteria depends on various factors, including the purpose of composting, local climate conditions, soil type, and available microbial resources.

Why Use EM Bacteria?

1. Improve Decomposition Efficiency: EM bacteria secrete multiple enzymes that break down complex organic substances such as cellulose, hemicellulose, and lignin, thereby speeding up the composting process.
2. Reduce Odor: Metabolites produced by EM bacteria, such as hydrogen sulfide and ammonia, can effectively inhibit the growth of pathogenic bacteria, reducing foul smells during composting and improving environmental friendliness.
3. Enhance Fertility: EM bacteria promote the growth of beneficial microorganisms like actinomycetes and yeasts, which produce plant growth regulators and other beneficial compounds, thereby increasing the fertilizing effects of compost.
4. Improve Soil Structure: EM bacteria increase microbial diversity in the soil, helping maintain and improve its biochemical properties, such as pH and nutrient cycling.
5. Lower Environmental Pollution Risk: By regulating microbial activity during composting, EM bacteria reduce the proliferation of harmful bacteria and pathogens, lowering environmental pollution risks.

Is EM Bacteria Always Necessary?

1. Cost Considerations: EM bacteria often require purchase or homemade preparation, which may increase composting costs. In some cases, if local microbial resources are abundant or naturally available, additional purchases may not be necessary.
2. Technical Requirements: Using EM bacteria demands specific knowledge and skills to ensure proper application. Without expertise, their effectiveness may be limited or fail to meet expectations.
3. Environmental and Ecological Impact: While EM bacteria generally benefit the environment, caution is needed to avoid overconsumption of local microbial populations or harm to specific species.
4. Alternative Methods: Under certain conditions, other methods can improve composting efficiency, such as physical methods (e.g., turning piles), chemical methods (e.g., adding carbon sources), or biological methods (e.g., introducing specific microorganisms).

How to Choose the Right Composting Method?

1. Define Composting Goals: Clarify whether the aim is rapid waste processing or long-term soil amendment.
2. Consider Local Climate and Soil Conditions: Different regions may require tailored composting methods and microbial combinations. For example, heat-resistant EM strains might be selected for hot and humid areas.
3. Evaluate Cost and Sustainability: Prioritize economic viability and long-term environmental benefits when selecting composting methods.
4. Conduct Small-Scale Tests: Before large-scale implementation, test composting effects and EM strain suitability on a small scale.

whether to use EM bacteria in composting depends on multiple factors. Decisions should balance costs, feasibility, environmental impact, and specific composting needs.
