Having worked hard in the building materials industry for nearly ten years, I have witnessed with my own eyes the most intuitive changes in the industry – from the past “emphasis on appearance and low price” to today’s “emphasis on environmental protection and health”. Green transformation is no longer an industry gimmick, but a real development trend.
Especially in recent years, with the tightening of environmental protection policies and the improvement of consumer health awareness, environmentally friendly decoration materials have completely broken the monopoly of traditional materials and gradually seized the mainstream market share.
Today, based on years of practical experience in material selection and construction, we will share the core technologies behind the green transformation of the building materials industry, talk about which environmentally friendly decoration materials are worthy of attention, as well as the core advantages and practical points of these materials, and help everyone understand the core logic of green building materials.
1. First clarify: green building materials ≠ “zero pollution”, focus on these three indicators
Many owners and practitioners have a misunderstanding, thinking that as long as “green building materials” are labeled, it is absolutely “zero pollution”.
In fact, this is not the case. The core of green building materials is “low emission, low pollution and recyclability”, rather than being completely free of formaldehyde and harmful substances. After all, during the production and processing of decoration materials, a small amount of harmful substances will inevitably be produced. The key is to control them within the safety limits stipulated by the state.
To determine whether a building material is a truly environmentally friendly material, you don’t need to look at the merchant’s propaganda. Focus on these three core indicators. Novices can get started quickly:
- Formaldehyde release: For wall and board materials, E0 level is preferred (formaldehyde release ≤ 0.050
mg/m³) or ENF level (formaldehyde release ≤0.025mg/m³), which is currently the most stringent environmental protection standard in China; - VOC content: coatings and adhesive materials, the lower the VOC (volatile organic compound) content, the better, and those that comply with national GB are preferred.
18582-2020 standard products to avoid long-term volatilization and harm to health; - Recycling rate: One of the core advantages of green building materials is that they are recyclable and recyclable, such as recycled aggregates and recycled wood-processed boards, which can not only reduce resource waste, but also reduce pollution during the production process.
This is also the core logic of the green transformation of the building materials industry: no longer just pursuing the cost performance and appearance of materials, but also paying more attention to environmental protection and sustainability, from production to use, reducing the harm to the environment and human body.
2. Core environmentally friendly materials 1: Water-based paint, the mainstream choice to replace traditional oil-based paint
In the field of decoration coatings, the most obvious green transformation is “water-based paint replacing oil-based paint”.
In the past, oil-based paint was the first choice for many homes and projects because of its strong adhesion and high gloss. However, it contains a large amount of VOC, benzene and other harmful substances. After construction, it requires long-term ventilation to disperse odors, which not only pollutes the environment, but also harms human health.
In recent years, water-based paint has gradually become the mainstream of the market with its advantages in environmental protection. Combined with many years of construction experience, we share its three core technical advantages and practical points:
- Outstanding environmental protection: it uses water as the diluent and does not contain harmful solvents such as benzene and toluene. The VOC content is well below the national limit. There is almost no pungent smell during construction, and it can reach the occupancy standard in 3 to 7 days with ventilation;
- Convenient construction: water-based paint dries quickly, at room temperature 2
– It dries in 4 hours, instead of waiting for several days like oil-based paint, which greatly improves construction efficiency, and it is easy to clean up after construction, and tools can be rinsed with water; - Wide adaptability to scenarios: whether it is walls, furniture, metal, or wood surfaces, water-based paint can be used, and the colors are rich and the glossiness is adjustable, which can not only meet the needs of decoration appearance, but also take into account environmental protection.
More than 90% of the renovation projects undertaken in recent years have used water-based paint. The most common feedback from owners is “little odor and quick move-in”. This is also the core reason why water-based paint can quickly capture market share.
3. Core environmentally friendly materials 2: Formaldehyde-free boards, the key to solving the hidden dangers of formaldehyde in decoration
During decoration, the main source of formaldehyde pollution is boards – traditional artificial boards use urea-formaldehyde resin as an adhesive, which will continue to release formaldehyde, even for several years. This is the core reason why formaldehyde exceeds the standard after many home decorations.
With the advancement of green transformation, formaldehyde-free boards have gradually become the mainstream of the market, completely solving the hidden dangers of formaldehyde in boards.
Many people think that formaldehyde-free boards mean “no adhesives”. In fact, this is not the case. Its core technology lies in the application of “environmentally friendly adhesives”. Three common types of formaldehyde-free boards are summarized, each with its own advantages. You can choose according to your needs:
- Formaldehyde-free added boards: MDI ecological adhesive is used to replace traditional urea-formaldehyde resin. No formaldehyde is added during the production process, and the formaldehyde release reaches ENF level. It is suitable for wardrobes and cabinets.
and other customized furniture; - Straw fiber board: made of crop straw as raw material and pressed with formaldehyde-free adhesive. It is not only environmentally friendly, but also can realize the recycling of crop waste. It is cost-effective and suitable for wall base.
Floor and ceiling boards; - Solid wood splicing boards: Made of natural solid wood, without the use of artificial board adhesives, the formaldehyde emission is almost zero, and it is the best environmentally friendly, but the price is high, suitable for families with sufficient budget.
It should be noted that although formaldehyde-free boards are environmentally friendly, you should also choose products produced by regular manufacturers to avoid buying “pseudo-formaldehyde-free” boards – be sure to check the product’s environmental testing report to confirm that the formaldehyde release amount meets the standards.
IV. Core environmentally friendly materials 3: Regenerated building materials, an important direction to realize resource recycling
The green transformation of the building materials industry requires not only “environmentally friendly production” but also “recycling”.
As an important direction of green transformation, recycled building materials have gradually seized market share by virtue of the advantage of “turning waste into treasure”. Especially in engineering decoration, their applications are becoming more and more widespread.
Based on engineering cases, we share three commonly used recycled building materials, as well as their application scenarios and core advantages:
- Recycled aggregate: made from crushed waste concrete and masonry, replacing traditional sand and gravel, used in road base and wall construction, which can not only reduce the pollution of construction waste, but also reduce the consumption of sand and gravel resources, and is extremely cost-effective;
- Recycled plastic building materials
: Using waste plastics as raw materials, processed into plastic pipes, floors, etc., it has the advantages of corrosion resistance, light weight, easy installation, suitable for outdoor decoration, bathrooms and other humid scenes, and can be recycled and reused; - Recycled wood panels: Made from waste wood and scraps as raw materials, sterilized and pressed, it can replace traditional solid wood panels and be used for furniture and suspended ceilings, which can not only reduce the waste of wood resources, but also reduce production costs.
The core value of recycled building materials is to achieve “resource recycling, low carbon and environmental protection”. With the iteration of technology, the quality of recycled building materials is getting higher and higher, gradually getting rid of the label of “inferior quality and cheap” and becoming an important choice for green decoration.
5. Practical pitfall avoidance: 4 minefields that are most likely to be stepped on when choosing environmentally friendly building materials
Many owners and practitioners want to choose environmentally friendly building materials, but because they do not understand the technology, it is easy to avoid pitfalls. Not only do they waste money, but they may also buy materials that are not environmentally friendly.
Combining many years of experience, we have summarized the 4 minefields that are most likely to be stepped on, and everyone must avoid them:
- Minefield 1: Only look at the “environmental protection label”, not the test report – many businesses label “green and environmentally friendly”, but there is no authoritative test report, and it is most likely “pseudo-environmental protection”. Be sure to check the CMA certified test report;
- Minefield 2: Blindly pursue “zero formaldehyde” and ignore overall environmental protection – the environmental protection of a single material does not mean that the overall decoration is environmentally friendly, such as for walls
Environmentally friendly coatings and high-formaldehyde sheets for furniture will still exceed the standard of formaldehyde overall; - Minefield 3: Thinking that the more expensive the environmentally friendly materials are, the better – there is no absolute direct relationship between environmental protection and price. For example, recycled building materials are cost-effective but not environmentally friendly.
Wrong, there is no need to blindly pursue high-priced materials; - Minefield 4: Ignoring the environmental protection of the construction process – even if the materials are environmentally friendly, the use of inferior adhesives and putty powder during construction will cause secondary pollution. Environmentally friendly auxiliary materials must be used during construction.
6. Finally, I would like to say: Green transformation is the long-term path for the building materials industry
After working in the building materials industry for nearly ten years, the biggest realization is that green transformation is not a “phased trend” in the industry, but the only way for long-term development.
With the continuous tightening of environmental protection policies and the improvement of consumers’ health awareness, non-environmentally friendly building materials will eventually be eliminated from the market. Only by adhering to the concept of environmental protection and deeply cultivating environmental protection technology can we gain a firm foothold in the industry.
The environmentally friendly building materials technologies and practical points shared above are the summary of many years of front-line experience. There is no complicated theory, and they are all content that everyone can quickly understand and get started with.
In fact, green decoration is not difficult. The core is “choosing the right materials and scientific construction”, which can not only protect the health of family members and users, but also contribute to environmental protection.
In the future, with the continuous iteration of technology, I believe there will be more environmentally friendly, higher-quality, and more cost-effective building materials, which will promote the green transformation of the building materials industry and allow environmentally friendly decoration to enter more homes and projects, achieving the goal of “decorating is environmentally friendly, and moving in means peace of mind.”
