Low-Carbon Transition Roadmap for Brick Machinery: Emission Sources Identification and Mitigation Strategies

 With the deepening of global climate change action, the building materials industry faces increasingly stringent carbon constraints. As the core equipment in block production, brick making machines urgently require systematic research and solutions to their carbon emissions. This paper takes the entire brick making process as the research object, constructing a carbon emission analysis framework covering raw material processing, molding, curing, and solidification, systematically identifying major emission sources and their generation mechanisms. Based on this, a multi-level, phased emission reduction pathway system is proposed, covering process optimization, equipment modification, energy substitution, and management improvement, providing theoretical basis and practical guidance for the low-carbon transformation of brick making machine production.

I. Introduction

The construction industry accounts for a significant proportion of global carbon emissions, and as a basic building material, the carbon reduction potential of block production has attracted much attention. Brick making machine production involves multiple carbon emission dimensions, including energy consumption, raw material conversion, and process emissions. Traditional research often focuses on single stages or end-use energy consumption, lacking a systematic analysis of the entire process's carbon emission structure. Furthermore, existing emission reduction schemes often rely on specific data, making it difficult to form a universally applicable theoretical framework. This study constructs a theoretical decomposition model of carbon emissions from brick machine production, exploring a logical system for emission reduction paths independent of specific figures, and providing methodological support for the industry to achieve carbon neutrality.

2.1 Emission Source Identification and Classification

Carbon emissions from brick machine production mainly originate from three levels:

Direct energy consumption emissions: including indirect emissions from fossil fuel combustion or electricity use, such as electric drive and heat supply.

Raw material conversion process emissions: involving greenhouse gases released during the physical and chemical changes of raw materials, such as crushing, mixing, and molding.

 Auxiliary system operation emissions: covering energy consumption emissions from auxiliary equipment such as cooling, dust removal, and transmission.

2.2 Emission Structure Analysis Method

A decomposition model is established based on the intersection of three dimensions: "process-energy-raw materials":

By production process: emission characteristics of pretreatment, molding, curing, and post-treatment stages.

By energy type: emission contributions from different energy carriers such as electricity, steam, and fuel.

By raw material category: carbon footprint differences of raw materials such as natural aggregates, industrial solid waste, and binders.

2.3 Emission Hotspot Identification Logic

Through qualitative comparison and theoretical derivation, the following emission hotspots are identified:

Energy conversion efficiency bottlenecks in high-energy-consuming processes

Inherent emissions from raw material chemical reactions

Redundant energy consumption due to poor system matching

5. Conclusion and Outlook

This study, by constructing a framework for decomposing carbon emissions from brick machine production, systematically reveals the formation mechanism and interrelationships of multi-dimensional emission sources. The proposed emission reduction path system breaks through the limitations of traditional reliance on specific data, forming a theoretical framework with universal guiding significance. Future research should deepen in the following directions: First, explore the path adaptation adjustment mechanism under different regional and climatic conditions; second, study the impact mechanism of policy tools such as carbon trading markets on emission reduction path selection; and third, construct a comprehensive evaluation system covering economic and technological feasibility. Through continuous theoretical innovation and practical exploration, carbon emission reduction in brick machine production will provide important support for the green transformation of the building materials industry and contribute to the achievement of global carbon neutrality goals.

This research provides brick machine manufacturers with a complete carbon emission reduction methodology, which can guide emission reduction planning and implementation in the absence of detailed energy consumption data.
