Feedstock Certification Toolbox for Ingeo

We've partnered closely with select NGO's, brands, and certifiers to create a comprehensive palette of tools for certifying the sustainability attributes of the current feedstocks used to manufacture Ingeo.

Genescan Certification

Today Ingeo is made from plant-based sugars and does not require a genetically modified (GM) feedstock. Current US corn growing practices produce a mixed stream of GM and conventional (non-GM) corn that we use for production. However, our final product, Ingeo biopolymer, does not contain any GM material due to the high heat used in the manufacturing process. Ingeo is certified to be free of any genetic material by Eurofins GeneScan, recognized by both government and NGOs as the leading authority for testing food, feed and raw materials. eurofinsus.com/gmotesting

Biobased Carbon Content Certification

Verification that 100% of the carbon in the Ingeo biopolymer originates from renewable agricultural resources instead of oil. 3rd party certification based on ASTM6866 is provided in Europe by Vinçotte and in the US by the USDA's BioPreferred program.

feedstock option 1
GM-Free Feedstock Sourcing Certification

Since the majority of US corn is genetically modified and it is not economically possible to set up a totally separate production chain dedicated to conventional (non-GM) corn. NatureWorks offers its feedstock sourcing program for those customers interested in supporting conventional (non-GM) agricultural practice. In this program a conventional corn volume, equivalent to the customer's needs, is purchased and mixed in the stream entering the corn wet mill. The customer receives copies of the farmers conventional seed purchase contract and verification that the corn produced is tested and delivered to the corn wet mill.

feedstock option 2
ISCC Plus Certification

International Sustainability & Carbon Certification (ISCC) PLUS is a European based 3rd party certification scheme certifying the sustainable production of renewable raw materials including the certification of the chain of custody. ISCC PLUS is an independent, third-party certification program fully owned and controlled by Germany-based ISCC Systems GmbH. It is available to the entire industry and comes with a palette of options which can be tailored to individual customer concerns. ISCC is the world’s first state-recognized system for certifying sustainability and greenhouse gas savings. ISCC Systems is active in 100 countries, and as of June 2016, has issued over 10,000 certificates, working with 32 certification bodies and with a basis of 82 members. Since the beginning of the relatively new ISCC PLUS program 92 certificates have been issued. The ISCC certification system is supported by the German Federal Ministry of Food, Agriculture and Consumer Protection via the Agency for Renewable Resources (FNR). www.iscc-system.org

Some of the production criteria include:

  • The farmer cannot source from land with high biodiversity, high carbon stock or from peatland. The reference year is 2008.
  • The farmer must meet sustainable agricultural practices concerning e.g. fertilizer & pesticide use, storage, disposal, tillage practices, equipment calibration and irrigation.
  • The farmer must have measures in place to protect the surrounding environment such as the natural vegetation and water courses; the farmer also has to take measures to avoid soil erosion and to increase soil organic matter.
  • The farmer must meet a set of social sustainability related criteria on e.g. child labor, workers protection, labor condition, land rights, training and water rights.

If a customer wants to participate in this program, NatureWorks contracts farmers which are then audited and certified along these criteria by an independent auditor and supervised by ISCC Systems GmbH. In this program a crop weight equivalent to the customer’s needs is purchased and mixed in the stream of corn entering the corn wet mill.

The program also includes the certification of the chain of custody. This means that the total volume of Ingeo received by the customer is traced back, via a “mass balance book keeping system,” to the equivalent amount of certified, sustainable corn produced and delivered to the corn wet mill.

feedstock option 3
ISCC Plus & GM-Free Feedstock Certification

Since in today’s ISCC PLUS program specification of GM/conventional corn is not a part of the requirements, a combination of NatureWorks’ feedstock sourcing program and the ISCC PLUS program is used. In this way both aspects are covered: conventional corn sourcing combined with sustainable corn production. We consider this as an intermediate solution and ISCC Systems is working on a project including the conventional corn requirement in the ISCC PLUS scheme.

feedstock option 4
Working Landscape Certificates

The US-based NGO, the Institute of Agriculture and Trade Policy (IATP), provides the Working Landscapes Certificate (WLC) program; an independent third-party scheme certifying sustainable agricultural production for emerging biomaterials sectors, including the bioplastics industry. WLC includes the requirement of using conventional corn seed. Both ISCC PLUS and WLC focus on sustainable farming practices, but have slightly different sets of criteria. www.iatp.org

Some of the production criteria for WLC's include:

  • Use of non-genetically modified (GM) crop varieties to protect biodiversity
  • No continuous annual crop production on same acreage
  • Soil testing on contracted acres and fertilization according to test results and state agronomic recommendations to assure that nutrients are used efficiently and are not likely to leach or run-off
  • No use of chemicals that are known human or animal carcinogens, including atrazine
  • Use of cover crops or assurance that at least 70 percent of crop residues remain on the entire field to minimize soil erosion
  • Creation of farm plan that includes information on biodiversity, energy use and greenhouse gas emissions to help identify and encourage improvements in sustainability areas not currently addressed by WLC’s
