The Origin of Recycling

In normal life, you may always recycle things. Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy. Recycling is a process to change materials into new products to prevent waste of potentially useful materials such as molded pulp packaging, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production.



Do you know the origin of recycling? Recycling has been a common practice for most of human history, with recorded advocates as far back as Plato in 400 BC. During periods when resources were scarce, archaeological studies of ancient waste dumps show less household waste—implying more waste was being recycled in the absence of new material. In pre-industrial times, there is evidence of scrap bronze and other metals being collected in Europe and melted down for perpetual reuse. In Britain dust and ash from wood and coal fires was collected by 'dustmen' and downcycled as a base material used in brick making. The main driver for these types of recycling was the economic advantage of obtaining recycled feedstock instead of acquiring virgin material, as well as a lack of public waste removal in ever more densely populated areas.

Recyclable materials include many kinds of glass, paper, metal, plastic, environmentally friendly packaging, textiles, and electronics. Although similar in effect, the composting or other reuse of biodegradable waste—such as food or garden waste—is not typically considered recycling. Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing. Beverage bottles were recycled with a refundable deposit at some drink manufacturers in Great Britain and Ireland around 1800, notably Schweppes. An official recycling system with refundable deposits was established in Sweden for bottles in 1884 and aluminium beverage cans in 1982, by law, leading to a recycling rate for beverage containers of 84–99 percent depending on type, and average use of a glass bottle is over 20 refills.

The Products Function of Molded Pulp Packaging

The molded pulp packaging is a new booming packaging material in recent years and it is a good substitute for wood. On the earthquake excellent performance, reasonable price, the whole cycle of degradation and pollution-free use of the advantages, it will entirely replace the EPS foam. The paper pulp compression molding product had the very long history, very early is a paper product member. It takes waste paper as raw material and added with moisture proof agent (aluminum sulfate) or waterproofing agent. According to different purposes, paper pulp packaging can be manufactured into various shapes and sizes to provide safe protection for the products due to its good buffer protection performance. Its basic process includes: materials preparation, molding, forming, drying and shaping.



It has four major advantages: wide source range; the raw materials include all kinds of waste paper or paper board; its production process is completely harmless to the environment and the products can be recycled; the volume is smaller than foamed plastics and it can be overlapped. This kind of products is mostly applied to industrial packaging.

Tolerance and protection is the first function of molded pulp packaging products. They should be reliable for packaging products, preventing the products from being damaged in the transportation, loading and unloading and use, and meet the requirements of the products' strength, stiffness and stability.

Easy to use makes the molded pulp products seem more human that their shape or structure should not harm the human body and they are convenient in operation, handling and carrying.

Molded pulp products extend the corresponding time and absorb energy through the character change of their own special structures when they are loading, thereby reduce the shock and vibration. It is different from cushioning mechanism of the foam plastic packaging products, due to the internal distribution of bubble hole, no matter what the product's shape is, it has good buffer performance. For instance, the paper pulp and foam materials are respectively used to make a big plane, the former is obviously good in buffer performance while and the latter is not. And plastic products cannot meet the requirement of large-scale package as the bad cushioning performance. So as for the pulp products, good structural design is the basic guarantee in its complete protection, improvement of the damping capacity in the process of transportation and handling.

The Modern Development of Molded Pulp

Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops or waste paper. Among them, wood provides about ninety percent of the basis for pulp production, while about ten percent originates from annual plants. The main applications for pulp are paper and board production. The furnish of pulps used depends on the quality on the finished paper. Important quality parameters are wood furnish, brightness, viscosity, extractives, dirt count and strength. Chemical pulps are used for making nanocellulose while the special pulp grade like molded pulp is used for industrial packaging.



In early years, as the boom of paper pulp industry, major environmental impacts of producing wood pulp have appeared which mainly come from its impact on forest sources and from its waste products. The impact of logging to provide the raw material for wood pulp is an area of intense debate. Modern logging practices, using forest management seek to provide a reliable, renewable source of raw materials for pulp mills. To meet the need of the times, some people and groups advocate using field crop fiber or agricultural residues instead of wood fiber as being more sustainable. Environmentally friendly packaging ways like pulped bagasse packaging has thrived.

There is enough straw to meet much of North America’s book, magazine, catalogue and copy paper needs. Agricultural-based paper is a guaranteed way to reduce the stress of paper production on old growth and endangered forests. What's more, some agricultural residue pulps take less time to cook than wood pulps. That means agricultural-based paper uses less energy, less water and fewer chemicals. Pulp made from wheat and flax straw has half the ecological footprint of pulp made from forests.

However, wood is also a renewable resource, with about ninety percent of pulp coming from plantations or reforested areas. Non-wood fiber sources account for about five to ten percent of global pulp production, for a variety of reasons, includes seasonal availability, problems with chemical recovery, brightness of the pulp, etc. Non-wood pulp processing requires a high use of water and energy. Nonwovens are in some applications alternatives to paper made from wood pulp, like filter paper or tea bags.

Recycling: The Best Way to Protect Environment

Recycling is a process to change materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production. Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy.



There are some ISO standards related to recycling such as ISO 15270:2008 for plastics waste and ISO 14001:2004 for environmental management control of recycling practice. Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, eco friendly packaging and electronics. Although similar in effect, the composting or other reuse of biodegradable waste—such as food or garden waste—is not typically considered recycling. Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing.

In the strictest sense, recycling of a material would produce a fresh supply of the same material—for example, used green sustainable packaging would be converted into new green sustainable packaging, or used foamed polystyrene into new polystyrene. However, this is often difficult or too expensive, so "recycling" of many products or materials involve their reuse in producing different materials instead. Another form of recycling is the salvage of certain materials from complex products, either due to their intrinsic value, or due to their hazardous nature.

Critics dispute the net economic and environmental benefits of recycling over its costs, and suggest that proponents of recycling often make matters worse and suffer from confirmation bias. Specifically, critics argue that the costs and energy used in collection and transportation detract from the costs and energy saved in the production process; also that the jobs produced by the recycling industry can be a poor trade for the jobs lost in logging, mining, and other industries associated with virgin production; and that materials such as paper pulp can only be recycled a few times before material degradation prevents further recycling. Proponents of recycling dispute each of these claims, and the validity of arguments from both sides has led to enduring controversy.

How to Put Green Packaging into Normal Life

In actual operation of food green packaging design, designers will generally take into account whether packaging materials will cause some of the environmental and human health hazards, but little attention they will pay to potential environmental and human health hazards from ink in the process of packaging printing. The green packaging such as eco friendly cosmetic packaging, often called the environmental friendly packaging, refers to the package which is harmless to the ecological environment and human health, can be reused and regenerated, and conforms to the sustainable development policy. Its concept has two meanings, one is to protect the environment, the other is to save resources, and neither can exist effectively without the other. Then how to put the theory into practice?



1.usage of paper material. The molded paper pulp packaging is environmental friendly because of its ingredient, that is natural plant fiber, which will soon rot in nature. The advantages of pulp molding products, besides light in weight, cheap and shockproof, they also have good breathability for food preservation. In the circulation of International commodities, paper material is widely used for packaging of eggs, fruit and glass products that are fragile and easy to be damaged.

2.Reusage of reproducible packaging materials. The land and forest is the basis of ecological balance. Indiscriminately deforestation will bring immeasurable disaster to human society. According to the current situation, reusable packing material should be taken into consideration. For instance, the glass bottles which used to hold beer, drink and soy sauce can be used repeatedly. The physical method is to dispose the products without any residues, and the processed material can be manufactured again.

3.Edible packaging material. It is a good method to deal with the problems between environment and food packaging waste. A company in Australia has developed a kind of edible potato packaging. After eating potato chips, people can also eat the package. Typical edible packaging material such as the packaging for candy and ice-cream may be familiar with people.

4.Biodegradable material. Biodegradable material has the functions and features of traditional packaging materials. It can be directly degraded with the effect of ultraviolet light and microorganism in soil and water.

Classification of Molded Pulp Packaging

Because the molded pulp packaging is made from some recycled products like newsprint and paperboard, it can be also called molded paper pulp packaging, which can be made in different shapes to give the goods protection, and it is inexpensive compared with other packaging materials.



Molded pulp has different types, but all of them are molded pulp biodegradable. Thermoformed type has the highest quality, of which the process uses "Cure-In-The-Mold" technology that produces well defined, smooth surfaced molded pulp products. The products are captured in heated forming molds which press and densify them and have the appearance of plastic material after being formed. The products are ejected from the heated molds in their finished state as opposed to being dried in a heated oven. Typical uses for this type are for point-of-purchase packaging and those applications where high definition and appearance are of prime importance.

Transfer molded products are the most prevalent type in use today. Prior to the molding process, the mesh is mated with a vacuum chamber that draws water through the mesh into the chamber, with the mesh mold suspended above a liquid return pool. The process uses vacuum forming and take-off or transfer molds, where the mold is an extremely fine wire mesh in the shape of the upper/exposed surface. The fibrous slurries are frequently made up of a high percentage or entirely of recycled newspaper, which produces a relatively smooth surface on one side and a fairly smooth surface on the opposite side with good accuracy and definition. Typical uses of transfer molded products are for packaging electronic equipment, cellular phones and other household and hardware items.

Thick-wall products are used primarily for support packaging applications. The surfaces are very rough on one side and moderately smooth on the opposite side. Product definition is moderate due to the use of relatively inexpensive single-pass molds and the use of mixed recovered paper and Kraft paper slurries. Typical uses are for edge and edge protector, heavy item packaging, auto replacement parts, molded pulp pallet trays etc.
