THE EFFECT OF REUSE, RECYCLING OF PLASTICS AND ESSENTIAL TO WASTE MANAGEMENT
CHAPTER ONE
INTRODUCTION
1.1Background of the study
Recycling saves energy, reduces raw material extraction and combats climate change. The vast majority of studies have found that recycling our waste is better for the environment rather than incinerating or land filling , The use of plastics in packaging applications is growing steadily. Most industrialized countries have systems for the collection and recycling of plastic packaging waste, either implemented on a full scale or on trial. An important aspect of plastic packaging recycling is that the types of plastics used for most packaging applications are inexpensive commodity materials. The price of corresponding virgin resins determines the ceiling for the price at which recycled materials can be sold for reprocessing.
Engineering plastics used in durable products are generally more expensive than the most common packaging plastics. This relation promotes the recovery of scrapped engineering plastics. For common packaging plastics such as polyethylene and polypropylene, all steps in the recovery and recycling process need to be highly cost-effective, unless sizeable subsidies are being paid [Bruder, 1997]. Techniques to facilitate the collection, sorting and reprocessing of plastic packaging waste are therefore urgently needed, as well as methods that can increase the value and the number of potential applications of the recovered materials. The price at which secondary material can be sold is related to the price of the corresponding virgin material. Price fluctuations therefore entail the need for an economic safety-margin (risk premium) in order to make investments in recycling facilities viable [Brandrup, 1997].
The generation and disposal of waste is an intrinsic part of any developing or industrial society. Waste, both from domestic and commercial sources has grown significantly in Nigeria over the past decade.
Recycling is one of the best ways for you to have a positive impact on the world in which we live. Recycling is important to both the natural environment and us. We must act fast as the amount of waste we create is increasing all the time.
The amount of rubbish we create is constantly increasing because:
- Increasing wealth means that people are buying more products and ultimately creating more waste.
- Increasing population means that there are more people on the planet to create waste.
- New packaging and technological products are being developed, much of these products contain materials that are not biodegradable.
- New lifestyle changes, such as eating fast food, means that we create additional waste that isn’t biodegradable.
