2016 Braskem | Annual Report 116 ‣ Glossary Biopolymer Thermoplastic resin produced from renewable raw materials Сар Emission limit Cracker Industrial plant where naphtha is processed into derivatives, such as ethylene, propylene, and other co-products Cracking (naphtha) Breaking molecules for ethylene production Eco-efficiency The ratio between the use of resources required to manufacture a given product and its production volume. Expresses productivity from an environmental standpoint Eco-indicators Environmental performance indicators Grid factor Average rate of GHG emissions resulting from generating electricity Flare Static mechanical safety equipment that is powered to burn chemical compounds that the industrial plant will not be able to process. Burning keeps hazardous compounds from being released into the atmosphere. Rotary clinker kilns Kilns to produce cement Grade (Resin) Type, Specification Investment grade Investment grade Reverse logistics A set of actions, procedures, and means enabling the collection and restitution of solid waste in the business sector, for reuse in its cycle or in other production cycles, or for other destinations Cap&trad market Cap & trade. A system composed of several parts in which emission quotas (permissions) are established for each participant, so that the sum of all quotas does not exceed the maximum fixed limit for the system. The cap is set to ensure that total system emissions are reduced from one period to the next. Trade is the trading of permissions between participants - those who can reduce their emissions further can sell their surplus permissions to those for whom reducing emissions is more expensive than buying permissions from others. That is, the trade mechanism allows the reduction sought by the group to be achieved at the lowest possible cost. Offsets Emission credits that may be traded in a cap&trade market. They are generated by the reduction of avoided emissions or emissions in accredited locations outside of market coverage (e.g. reforestation). These securities may be used as compensation by participants in a cap&trade market who have exceeded their emission limit p.p. Percentage point Raffia Fibers used to manufacture bags for transporting fruit or small loads Ramp-up Term in economy and business defining the initial stage of industrial production Risk rating (of processes) Process safety index established by insurance companies Second generation (in the petrochemical industry) Second generation units, producers of intermediates and thermoplastic resins (PE, PP, and PVC) Spread Margin (of profitability) Tagalong Mechanism that gives minority shareholders the same rights as controlling shareholders in the event of sale or transfer of control.
