BASF offers carbon-neutral neopentyl glycol and propionic acid

BASF will offer for the first time neopentyl glycol (NPG) and propionic acid (PA) with a  cradle-to-gate product carbon footprint (PCF) of zero. Produced at BASF’s Ludwigshafen Verbund site in Germany, the products are available globally as “NPG  ZeroPCF” and “PA ZeroPCF.” 

BASF  is today among the leading producers of neopentyl glycol and propionic acid globally.  

Neopentyl glycol is used in powder coatings, especially for the  construction and automotive industries as well as for household appliances.  Other  areas of application for NPG include the manufacture of lubricants, plasticizers and  pharmaceuticals: It is used as a building block in the synthesis of, for example,  hormones, cardiovascular drugs and painkillers. 

Propionic acid, which is fully biodegradable, is used as a mold inhibitor for the preservation of food and feed grains. In this application, PA offers economic and ecological benefits over preservation through drying or  storage in airtight silos. Other application areas of PA include the production of crop  protection agents, flavors and fragrances, pharmaceuticals, solvents and  thermoplastics. 

BASF produced the zero product carbon footprint for NPG and PA by  using renewable raw materials in its unique Verbund production system via its  biomass balance (BMB) approach. BASF additionally used renewable  energy to manufacture NPG.

NPG ZeroPCF and PA ZeroPCF are “drop-in” solutions. According to BASF, they are identical in quality  and properties to the standard products, allowing customers to use them in their  production without the need for adjustments to their existing processes. In this way,  customers can simply and efficiently reduce emissions from purchased goods or  services (Scope 3) and increase the share of renewable raw materials in the value  chain, thus contributing to the shift to a circular economy. 

Biomass balance approach using waste-based renewable materials  

BASF manufactures NPG ZeroPCF and PA ZeroPCF in its integrated Verbund  production system applying its biomass balance approach. For this, BASF feeds renewable raw  materials into its Verbund in the very first steps of chemical production and attributes  a corresponding share of the renewable raw materials to specific sales products by  means of a certified mass balance method. The renewable raw material used is  waste-based. BASF’s biomass balanced products are certified according to  recognized standards like either REDcert2 or ISCC plus.3 In the production of NPG  ZeroPCF, BASF additionally uses renewable energies via Renewable Energy  Certificates.  

The PCF comprises the total greenhouse gas emissions that occur until the product  leaves the BASF factory gate for the customer, from the extraction of resources  through manufacturing of precursors to the making of the final chemical product  itself. On its journey to achieve net zero CO2 emissions by 2050, BASF is the first  large chemical company to make the individual carbon footprints of all its sales  products available to its customers.  

Certified Carbon Neutral by the Carbon Trust 

BASF has achieved Carbon Neutral certification from global climate change  consultancy the Carbon Trust for its NPG ZeroPCF and PA ZeroPCF. The Carbon  Trust certifies products as Carbon Neutral that are either carbon neutral through  temporary natural upstream carbon sinks like plants or through carbon credits  purchased by the manufacturing company. BASF achieves the cradle-to-gate  product carbon footprint of zero for NPG ZeroPCF and PA ZeroPCF without  purchasing carbon credits. The certification will be reviewed on an annual basis.
