This is a research project in partnership between Engr308 Technology and the Environment and The Sustainability Office and HSU Dining at Cal Poly Humboldt during Fall 2017. The project includes analyzing the various impacts of OZZIs impacts on campus. Client leads are:
Our object is to analyze the impacts of OZZIs on campus and the effects of HSU's policy regarding OZZIs versus disposables. A secondary goal is work towards a recommendation regarding the policy. Impacts will be focused primarily on $, CO2, and Energy. Final products will include:
Embedded Energy describes the energy used throughout the lifecycle of a product. The lifecycle of a product includes raw material extraction, transport, manufacture, assembly, installation, disassembly, deconstruction and/or decomposition.[1]

The units are produced in China, then shipped to Houston, Texas to G.E.T. Enterprises, then shipped to their final destination (i.e. HSU). The containers are shipped by the dozen, weighing a total of 7lbs and occupying 0.73 ft³ of space[7]
HSU's other disposable eating containers
HSU uses a 9" white plate (WHBRG-09) which is molded by Bridge Gate from Boulder, Colorado. These 9" white plates are molded from a sugarcane byproduct called bagasse. Each box/case contains 500 plates which is about 19 pounds, therefore each plates weighs roughly 0.038 pounds. Although these plates are molded by Bridge Gate, the cases are distributed by Sysco distributions, either from Sacramento or San Jose, California to Cal Poly Humboldt. After usage, these disposable plates can be discarded naturally or commercially (advance) composting. According to worldcentric, the degradation cycle for bagasse is usually between 2-4 months for natural compost and 1-3 months for commercial compost.[8][9][10][11][12]
HSU uses 24-32oz (#BO-SC-U24) bowls made by World Centric.[13] The bowls are made from unbleached plant fiber, which mainly consists of wheat straw (or the stalks from wheat plants)[14] They are sent to HSU in boxes with a 500 count, and a gross weight of 31 pounds. They are manufactured in China, however they are shipped afterwards to warehouses located in San Leandro, CA and Grove City, OH. Wheat straw consists of cellulose, hemicellulose, and lignen[15] Dry matter of wheat straw contains about 50% of carbon, 6% hydrogen, and 42% oxygen[16] Manufacturing production materials from raw materials from one pound of wheat straw has an energy consumption of 0.66kwh, water consumption of 13.33 gallons, and CO2 emissions of 0.69 lbs Manufacturing products from one pound of wheat straw has an energy consumption of 2.066 kWh and CO2 emissions of 2.02 lbs[17]
Embedded Energy describes the energy used throughout the lifecycle of a product. The lifecycle of a product includes raw material extraction, transport, manufacture, assembly, installation, disassembly, deconstruction and/or decomposition.[18]
Some brief introduction and general description, then find numbers and support for the following:
Cradle to Polymer(PP): 73.4 MJ/kg[25]
Production of 1 tonne PP from natural gas emits 2 tonnes of CO2. Production of 1 tonne of PP pellets from recycled PP bottles emits 1.2 tonnes of CO2.[26]

General embedded CO2 in shipping by sea
10 Grammes of Carbon Dioxide to carry 1 Ton of Cargo 1 Kilometer[28]
General embedded energy in shipping by land General embedded energy in CO2 shipping by land Truck (> 40 tonnes): 80.0 Grams per tonne-km[31]
3-Compartment: 9 inch X 9 inch X 2.5 inch deep
