The increasing awareness of the environment has raised so much concerns in the way we live and the manner to which we dispose our waste. The rapid growth in polymer production has resulted in increasing concerns about the consumption of nonrenewable resources and the environmental impacts associated with its production and disposal. Polymer waste is one of the major components in municipal solid waste and is increasingly becoming a huge burden in industrialized nations. The rise in the use of plastic, coupled with increasing concerns about its disposal, has led to a renewed interest in its recycling and recovery. The technologies involved in the recovery and recycling of polymers are rapidly growing, however, there is no specific pattern of treating polymer waste. The technology depends on the type of material used in the production and consumption pattern. This chapter, therefore, discusses the patterns of polymer consumption, the environmental concerns, and different modes of recycling polymer waste.

Abstract Rice is an important staple food for more than half of the global population and one of the largest water consumers on earth. Improving the efficiency of water embedded in rice production and supply could have great implications for food and water security. This study starts from Yunnan, a traditional rice producing and consuming province in southwest China, and analyses its rice supply structure and dynamics, together with embedded water footprints (WFs) of three other regions: Northeast China, South and Southwest China and Southeast Asia. The results show that Yunnan has been under through drastic food change in the past decades, leading to increasing production and supply gap. Yunnan is found to have the least WF (778.2 m3/t) for rice production across the study regions, while Northeast China consumes the highest blue WF (364.6 m3/t) and blue to total WF ratio (97.7%). The study indicates that Northeast China is at risk of groundwater deficit due to rice production and export and the current rice production and consumption pattern is inefficient. The study suggests that policies for groundwater extraction, water resource price and international trade need to be in place to ensure sustainable food supply and water use at regional and national levels.

The Way

Seafood supply chains are complex, not least in the diverse origins of capture fisheries and through aquaculture production being increasingly shared across nations. The business-to-business (B2B) seafood trade is supported by seafood shows that facilitate networking and act as fora for signaling of perceptions and values. In the Global North, sustainability related certifications and messaging have emerged as an important driver to channel the demands of consumers, institutions, and lead firms. This study investigates which logos, certifications, and claims were presented at the exhibitor booths within five seafood trade shows in China, Europe, and USA. The results indicate a difference in the way seafood is advertised. Messaging at the Chinese shows had less of an emphasis on sustainability compared to that in Europe and the USA, but placed a greater emphasis on food safety and quality than on environmental concerns. These findings suggest cultural differences in the way seafood production and consumption is communicated through B2B messaging. Traders often act as choice editors for final consumers. Therefore, it is essential to convey production processes and sustainability issues between traders and the market. An understanding of culture, messaging strategies, and interpretation could support better communication of product characteristics such as sustainability between producers, traders, and consumers.

This study is going to deal with the perception of people about solid waste and the initiative of Swachh Bharat Mission in Patna. Solid waste management is the biggest issue of global. Population of area are continued to rise and consumption pattern are changing. The health and environmental implications associated with Solid Waste Management increasing at high level, mainly developing countries because they are not able to manage the waste properly. India is the second highest ranking country in term of population and the most purchasing power country in the world. Solid Waste Management in Patna is very poor stage. The waste generally disposed on the roads by the households and subsequently collected by street sweeping staff of Patna Municipal Corporation by JCB. The proper required equipment is not available in the Patna Municipal Corporation Department. Patna has many issues related to Municipal Solid Waste such as lack of infrastructure, unavailability of dumping space for garbage, less number of municipal worker, Gender discrimination in cleanliness, awareness of cleanliness, unwillingness of people for maintaining the cleanness, eating habit especially Pan eaters spit all over the street.

Abstract A survey was conducted using structured questionnaire to evaluate the production and consumption pattern of gurasa,an indigenious flat bread consumed in northwestern Nigerian comprising of seven States. Also nutritive value of randomly selected gurasa samples were analyzed. Ninety eight percentage (98%) sampled consume this productany time of the day (52%) and few others for breakfast(27%), usually accompanied with yaji(spiced defatted peanut powder)(54%). More producers were males (25.7%), more consumers (32%) females mainly in the age group of 21-31. Kano, Katsina, Kaduna, Jigawa  harbour 74.3% of producers and 79% of consumers. Keep quality was less than five days (60%), less three days (40%), therefore improvement in keeping quality (41%), (37%) solicited. Yong adults were the producers who obtained the skill from parents/relatives (91%), those with less than five years were 40.5% and 6-11 years of experience, 43.3%. Local oven fueled by corn stalk were involved in baking 81% and 75.7% respectively. Need for expansion called for assistance in the area of working capital (56.75) and provision of storage facility (36.72%) to further improve profitability through greater turnover. Moisture, protein, fat, ash, dietary fiber and carbohydrate of sampled gurasa varied significantly from 28.09-30.11%, 8.96-11.68%, 4.03-5.00, 1.79-3.11%, 0.92-1, 12% and 50.00-55.04%. Weight, volume and specific loaf volume varied significantly from 108.34-119.27g, 211.96-260.17ml and 1.93-2.22ml/g respectively. It is suggested that government intervention is necessary to modernize, harmonize and regulate this subsector that help to eliminate food insecurity. Nutritional quality could be improved by partial substitution of the refined wheat flour with pulse flour since majority could not afford animal protein. Key words: Flat bread, Gurasa, Nutritive value, Production survey, Consumption survey.
