Natural rubber degrades in a microbially rich, moist soil over the period of 1-2 years. Recent studies have shown that only around 35% of all rubber products consist of natural rubber. The larger part of rubber components is in fact made of synthetic rubber or so-called rubber composite materials. Those synthetically manufactured compounds are not biodegradable rubber and require chemical recycling. BioPowder.com aims at facilitating this process by providing fully natural rubber additives made from renewable side stream resources.
Like most industrial materials, rubber is not used in its pure form. It is often mixed with certain chemicals, better known as additives, to improve its physical properties and performance characteristics. These additives play several critical roles, such as enhancing the overall quality of the rubber, improving durability, and resistance against various environmental elements like UV rays, heat, and harsh chemicals. Rubber additives, divided into different categories – such as fillers, plasticizers, processing aids, accelerators, and retarders – are meticulously selected based on the intended use of the final rubber product. For instance, carbon black, a common filler, enhances the strength and endurance of the rubber, whereas plasticizers like oils or waxes are used to increase the flexibility of the rubber. While traditional rubber and associated additives can be non-environmentally friendly, the industry has seen a shift towards more sustainable materials. One such innovation are biodegradable rubber additives from BioPowder.com: This type of rubber additives, made from natural, renewable resources like olive pits, degrades naturally over time, reducing its impact on the environment.
The chemical industry provides thousands of additives used in rubber compounding. When developing a rubber compound, the choice of additives depends on the desired mechanical properties as well as on environmental and financial considerations. Most rubber composite materials are designed to ensure high levels of tensile and impact strength as well as stability and thermal resistance. In biodegradable rubber, natural fibres and micronized powders are often added as reinforcing fibres and texturizers. The high particle hardness of BioPowder.com rubber additives can in addition boost strength and abrasion resistance. Also, textured surface effects can be created when the rubber composite is enriched with natural powders of a larger grain size.
Mainly for reasons of texture, mechanical properties and bio-based nature as explained above.

When it comes to the matter of whether rubber is biodegradable in water, an unambiguous response would be that conventional rubber cannot readily degrade in water. Rubber is made from polymers of isoprene, which are robust chains that resist degradation on exposure to water. Hence, under normal conditions, rubber materials like tires and latex gloves, will not biodegrade in water or even in a landfill. Nonetheless, the industry has seen advancements that have led to the creation of biodegradable rubbers. These are carefully engineered materials that can break down under certain conditions. In general, these would require specific microbial action and aren't designed to degrade in any setting. Certainly, this doesn't imply that traditional or biodegradable rubber should be freely discarded in water sources.
No, silicone rubber, a synthetic compound featuring a backbone of silicon and oxygen atoms, does not readily decompose or degrade in the environment. This particular type of non-biodegradable rubber is highly durable, resistant to heat, and widely used in many consumer and industrial applications due to its robustness and resiliency. There is a belief that silicone rubber degrades into silicates, water, and carbon dioxide when exposed to environmental factors such as ultraviolet light or extreme temperatures. However, this biodegradation process involves a significant period and only occurs under specific conditions, far from the regular composting environment required for most biodegradable materials. Therefore, silicon-based rubber, despite its utility and versatility, is not an eco-friendly option when considering biodegradability. Its end-of-life disposal presents environmental challenges due to non-biodegradability. Seeking alternatives is encouraged, such as natural rubber or other forms of biodegradable rubber, designed to break down more readily in the environment, contributing to lowering the overall ecological footprint.
The answer to this frequently asked question requires some nuance. On the whole, yes, latex rubber does possess biodegradable characteristics. Latex originates from the sap of the rubber tree, Hevea brasiliensis, which is a renewable resource. Being a natural product, it can undergo decomposition, much like organic waste. However, the rate of its biodegrading process heavily depends on environmental conditions such as weather, temperature, humidity, and the presence of microorganisms. Additionally, it's worth mentioning that not all products labeled 'latex rubber' may be entirely made of natural latex. These items often integrate synthetic materials which do not decompose as easily or may cause environmental harm due to non-biodegradability. So, while latex rubber has the potential for being a sustainable, biodegradable rubber solution, it is essential to understand the product’s content. BioPowder.com suggests that consumers ensure latex rubber products are predominantly composed of natural latex for true biodegradability. This way, you can make educated decisions that uphold your principles of environmental responsibility.
When understanding the environmental impact of different materials, it's important to consider their biodegradability. Generally, rubber, specifically natural rubber, has a more accelerated degradation process compared to conventional plastics. The reason being, natural rubber consists of organic compounds, primarily isoprene, that break down more readily in the environment. On the contrary, conventional plastics, particularly those derived from petrochemicals, have complex molecular structures which resist degradation. They could persist in the environment for hundreds to thousands of years before they degrade fully, causing significant environmental problems. However, not every rubber is created equally. Synthetic rubbers, much like plastics, can resist natural degradation processes. For those looking for eco-friendlier solutions, biodegradable rubber, specially designed to decompose faster, is a promising alternative.
Vulcanization of rubber, a process crucial for enhancing the durability and usability of rubber, involves a variety of additives, each with a specific role. Predominantly, sulfur is used as a vulcanizing agent, fostering cross-linking between rubber molecules. This sulfur-crosslinking enhances the rubber quality, making it resistant to temperature changes and mechanical stresses.
Accelerators are another key additive type that speed up the vulcanization process. They include substances like thiurams, guanidines, and thiazoles. Activators such as zinc oxide and stearic acid are utilized to boost the efficiency of accelerators, providing optimal vulcanization conditions.
The use of retarders like phthalic anhydride or salicylic acid might be critical when premature vulcanization, potentially detrimental to the process, needs to be avoided. Moreover, specialty additives like fillers and plasticizers are integrated into the mix to modify its physical properties, improving qualities such as tensile strength, flexibility, and processability.
BioPowder.com leverages its expertise in producing eco-friendly, biodegradable rubber additives to incorporate all these elements skillfully.

Vulcanized rubber, a form of hardened rubber commonly used in myriad products such as tyres, footwear, sporting goods, automotive parts, and many more, is known for its superior durability and resilience. Unfortunately, it is this very feat of strength and longevity that often positions it in opposition to the cause of environmental sustainability. Contrary to biodegradable rubber alternatives, vulcanized rubber does not readily degrade or decompose over time in natural environmental conditions. Subsequently, this non-biodegradable nature of vulcanized rubber poses significant environmental problems. Not only does it contribute to the growing global waste predicament, but its inability to decompose also increases its potential to leach harmful chemicals into the nearby soil and groundwater. So, vulcanized rubber composites show a high demand for our biodegradable rubber fillers such as our bio-additives from olive stones. Using them as rubber fillers, the percentage of biodegradable material in the rubber composites is increased.
Biodegradable rubber and biodegradable polymers are materials designed to break down naturally over time. Biodegradable rubber is a specific type of rubber that can degrade through microbial activity, often made from natural materials that can be decomposed by organisms in the soil.
