1. Introduction
An increase in global population leads to both increased food and energy consumption. The global population
increases and these activities associated with energy consumption generates more and more green house gas (GHG)
to the atmosphere. Therefore, we must realize greenhouse gas emission by estimating the carbon footprint from
production, transportation, and disposal. Data of carbon footprint will show on the labels’ products that indicate
amounts of green house gases through life cycles of products. They help consumers to choose a product that is more
environment-benign. The carbon footprint can be estimated by life cycle assessment (LCA). It is used in various
types of industries, namely, construction, water treatment disposal, etc. In plastic production also, the evaluation of
the carbon footprint can be performed. Carbon footprint usually stands for the amount of CO2 and other green house
gases, emitted over the full life cycle of a process or product [1]. Life cycle assessment associated with full life cycle
of product (Business-to-customer: B2C) and partial life cycle of product (Business-to-business: B2B). B2C
evaluates green house gas emission from manufacturing raw material, production, uses, and disposal, but B2B
evaluates green house gas emission from manufacturing to before transporting product to customer.
Plastic products from petrochemical industries are not eco-friendly due to having the high carbon footprint. Until
recently, bioplastics has been explored as alternative to substitute the fossil-based plastic e.g. PE,PP. Bioplastics are
polymers that are manufactured into the commercial products from natural sources or renewable resources, and they
can also be biodegradable[2]. Thus, this study aimed to study the carbon footprint and green house gas emission by
life cycle assesment typed B2C of bioplastic straws ) PBS/PLA (and polypropylene straws through life cycle, from
producing raw materials, transportation, production, and disposal.
