The Kingdom of Plastic

Who doesn't know plastic? Everyday all people use plastic to help them for carrying and storing their stuff. Plastic is a common to all people. In general, all plastic look the same, although with different color and size. Spesifically, there are many types of plastic, based on their usage.  Let's we learn more about plastic.

Plastic 1: Polyethylene Terephthalate (PET or PETE)
Commonly recycled, PET is semi-rigid and very lightweight. It's best suited for single-use containers as it can break down when exposed to light and heat, causing it to leach. PET can also be recycled into fabric, similar in strength and appearance to virgin nylon. Plastic marked with an SPI code of 1 is made with polyethylene terephthalate, which is also known as PETE or PET. PETE-based containers sometimes absorb odors and flavors from foods and drinks that are stored inside of them. Items made from this plastic are commonly recycled. PETE plastic is used to make many common household items like beverage bottles, medicine jars, peanut butter jars, combs, bean bags, and rope. Recycled PETE is used to make tote bag carpet, fiberfill material in winter clothing, and more.

Call for Paper: International Student Conference on Environment and Sustainability (ISCES) 2015

The International Student Conference on Environment and Sustainability (ISCES) was initiated as an annual event to provide international students with a platform to work together, exchange ideas and understanding on critical environmental issues and jointly create new solutions. Supported and funded by the United Nations Environment Programme (UNEP), Tongji University and Beijing Green Future Environmental Foundation, and organized by UNEP-Tongji Institute of Environment for Sustainable Development (IESD), ISCES was successfully held over the last four years (2011, 2012, 2013,2014), attracting approximately 300 students every year from more than 40 countries across the globe and contributing to the dissemination of good practices and concepts on environment and sustainability amongst student communities.

The “2015 International Student Conference on Environment and Sustainability (ISCES 2015)” will be launched on the World Environment Day (June 5) and last for a week. This year, the event will attract the sustainability-oriented enterprises and NGOs to attend. With the support of UNEP, Tongji University and Beijing Green Future Environmental Foundation, plus the experience over the past three years, we believe that this year’s conference will be another milestone and success in promoting good practices and concepts of sustainable development among university students.

My experience when I joined ISCES 2014 was very amazing. Every student from all countries were gather and discuss about environmental issues in their country. We brought some ideas as the solution for environmental problem in our environment around. All students who are selected as the participant, have presented their poster at the poster session, discuss in 5 fields of environmental issues, interactive dialogue, green campus tour, field trip, and amazing one is cultural night. In this amazing of chance, I brought my thesis as the topic of my poster. It was about solid waste management in beach resort area.You can download my presentation by clicking this link ISCES 2014 Presentation

How to Analyze: Solid Waste Generation and Composition Sampling

In a solid waste management planning, we need some informations about the existing condition of solid waste itself. Based on solid waste management literature, solid waste management should be adjusted to the generation and its characteristics for efficiency and effectiveness.Tchobanoglous et al (1993) mentions about the classification of solid waste based on their source, they are:
1. Residential waste: foodwaste, paper, leather, yardwaste, ash, wood, plastic, and hazard
2. Commercial waste: paper, plastic, carton, metal, wood, foodwaste
3. Institutional waste: paper, plastic, wood, foodwaste, glass
4. Constructional waste: wood, metal, steel, concrete, ash
5. City service waste: yardwaste, plastic, paper
6. Processing building waste: sludge, ash
7. Industrial waste: ash, hazardous waste, plastic
8. Agricultural waste: foodwaste, hazardous waste
Solid waste generation is the amount of waste generated by the source in certainly unit of time. Generation rate is affected by the amount of population, industrial level, social economy, and commercial activity in the society (Babayemi et al., 2009). Solid waste generation is the effect of production and consumption of the society in every economic level. This solid waste generation is related to solid waste management, such as equipments, routing, recycling facilities, and final disposal facilities.
Solid waste composition is the representative of each constituent and its distribution of the waste and expressed in persentage of weight (%). Composition of solid waste is very important to plan or evaluate the equipment needed, system and program management of solid waste, and handling system. Solid waste constituents is classified into organic and anorganic waste. Organic waste such as: foodwaste, paper, plastic, leather, cloth, rubber, yardwaste and woods. Anorganic waste such as glass, tin, metal, and steel (Tchobanoglous et all., 1993). Upadhyay et all., (2012), classify the solid waste composition into 4 class, they are:
1. Recyclable waste: paper, plastic, glass, metal
2. Poisonous waste: paint, pesticide, insecticide, battery, and drugs
3. Compostable waste: foodwaste, leaves, yardwaste, vegetables, fruits
4. Infectious waste: blood, syringe, laboraturium waste, cotton waste
All of waste composition will affect the waste density, disposal technique, and potencial of reuse, reduction, and recycle processing.
In this part, I want to share about how to do solid waste generation and composition analysis based on Indonesia Standard Method: SNI 19-3964-1994

1. Location
Sampling location is divided into 2 types, they are residential and non residential.
Residential:
- Permanent with high economic level
- Semi permanent with medium economic level
- Non permanent with low economic level
Non Residential: shop, office, school, market, street, hotel, restaurant, public facilities

2. Frequency
Sampling conducted in 8 days continuously, in same location, in the middle time of dry and wet season. 

3. Measurement and calculation
- The units used for generation measurement are liter/unit/day and kg/unit/day
- The units used for composition  measurement is persentage (%)
- Volume measurement use a container in size of 40 Liter with weight measurement before
- Volume measurement use a container in size of 500 Liter with weight measurement before

4. Tools and Equipment
- Plastic bag with volume of 40 Liter
- Volume measurement container in size of 20 cm x 20 cm x 100 cm with height scale sign
- Volume measurement container in size of 50 cm x 50 cm x 100 cm with height scale sign
- Weigher with scale 0-5 kg and 0-100 kg
- Moving tools and gloves
5. Action
a. Spesify the sampling site
b. Spesify the number of surveyor
c. Prepare the tools and equipment
d. Distribute the plastic bag with certainly sign to the host of waste source a day before we begin
e. Record the number of each waste source
f.  Collect all of the plastic bag which is already filled with trash
