Tire road wear particles (TRWPs) are one of the largest sources of microplastics to
the urban environment with recent concerns as they also provide a pathway for
additive chemicals to leach into the environment. Stormwater is a major source of …
Presumably any rosin or terpene derivatives used in tire-making will be subject to the same distribution.

thermal stability, flexibility, roughness, hardness, abrasion resistance, mechanical
properties, etc., were improved by modifying solvent based alkyd resin and water …
G Cazaudehore, R Guyoneaud, P Evon… - Biotechnology Advances, 2022
Growing concern regarding non-biodegradable plastics and the impact of these
materials on the environment has promoted interest in biodegradable plastics. The
intensification of separate biowastes collection in most European countries has also …
The concept of biodegradable plastic seems to me to be one that has come and gone because it would surely conflict with the efforts to recycle plastics which is the big driver from governments and industry today.

atmospheric oxygen leads to the formation of a mixture of terpene … Then the
mixture was exposed to steam distillation in order to separate monomers (they
HTML]Future of forest industry in carbon-neutral reality: Finnish and Swedish visions
S Lipiäinen, E Sermyagina, K Kuparinen, E Vakkilainen - Energy Reports, 2022
The forest industry is a significant emitter of CO 2 and thus it needs to transform
toward a more sustainable operation in order to contribute to tackling climate
change. This paper looks at the progress, tools, possibilities, and barriers of Finnish …
This paper can be downloaded for free. The “future” of the CTO pine chemicals industry, according to this study, is biofuel in the pulp & paper mills. At the least it will raise the price of CTO and hinder its availability in Scandinavia.
S Wang, X Chen, J Liang, X Wei, H Mo, K Deng… - Journal of Chemical & …, 2022
… Since it is very difficult to experimentally measure all the possible combinations of
terpene components in pine oleoresin equilibria (VLE) systems, it is essential to
make measurements on some systems to provide results that can be used to …
This takes me back to my R &D days when I tried to be an engineer. Useful data for designing a still for oleoresin separations.
JD Woodroffe, BG Harvey - Energy & Fuels, 2022
Three high-energy density fuels were generated in a one-pot reaction from the [4+4]-cyclodimerization and cross-coupling of isoprene and myrcene using a homogeneous iron
pyridineimine (PDI) catalyst. The resulting mixture of C10, C15, and C20 regio- and …
Seems like a wasteful use of valuable turpentine.
Y Qin, X Chen, L Wang, X Wei, W Nong, X Wei, J Liang - Molecules, 2022
… Turpentine is a terpene mixture mainly composed of monoterpenes such as (−)-α-pinene,
β-pinene, camphene, p-cymene, and sesquiterpenes such as longifolene and (−)-β-caryophyllene.
The monoterpenes are volatile components in a boiling point range of 155–175 C at …

T Tossavainen - 2022
… oil and tall oil pitch samples on heat transfer surface with a commercially
available fouling tester. Further, the aim was to identify components and compounds
causing fouling from different feeds. Studied feeds consisted of different crude tall oil …
An interesting and useful study of what causes evaporator fouling in tall oil distillation and how to minimize it.

… However, crude tall oil refining also produces side-products, such as tall oil rosin
and tall oil pitch, which find use in many different applications, especially in the
technochemical field (Routa et al. 2017). Cellulose can also be broken down to the …
An interesting predictive analysis of the forest industry. Thought-provoking. Not much about tall-oil except that it is and will be going into biodiesel due almost entirely to government mandates and subsidies. I guess that at least this will maintain scarcity and a high price for this important feedstock. Lignin is the future, it seems. Maybe the Pine Chemicals Association needs to expand its interests to include it.
