  • Degradation of biodegradable plastics under controlled composting conditions

    The management of solid waste is a growing concern in many countries. Municipal solid waste is a major component of the total solid waste generated by society, and the fraction of municipal solid waste made up of plastic materials continues to increase. The composting of plastic materials along with organic wastes will help society to usefully recycle more of its solid waste and divert it from ...

  • The search for sustainable plastics

    As petroleum-based polymers foul our oceans and litter our lives, researchers seek more environmentally friendly ways to meet demand for durable, versatile materials. The fate of the world’s oceans may rest inside a stainless steel tank not quite the size of a small beer keg. Inside, genetically modified bacteria turn corn syrup into a churning mass of polymers that can be ...

  • The physical, chemical and microbial characteristics of biodegradable municipal waste derived composts

    A comparative study of the physical, chemical and microbial properties of 12 composts sourced from United Kingdom commercial composting plants was carried out. The aim was to ascertain whether these composts could be used as growing media or for application to agricultural land. The composts were produced from either source segregated biodegradable municipal waste (BMW) or mixed municipal solid ...

  • Compostable Plastics And Environmental Marketing Claims

    According to a bottled water survey conducted by Perception Research Services International (PRS) for Brand Packaging published in August 2011, where shoppers were interviewed in person to gain some insights on marketing claims, environmental and recycling messages were misunderstood and not even noticed by a majority of consumers interviewed. In fact, only 50 out of 200 shoppers even noticed the ...

  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...

  • The future of plastics - Is there a solution to this huge waste management problem?

    Plastic - it has become the cornerstone of our modern life style, and one of the most challenging global waste management problems. So beneficial in countless ways, this nearly indestructible material is littering our environment on land and sea. Difficult to recycle, as post-consumer waste, and hard to break down, plastic in its many forms has become a serious environment problem. But solutions ...

  • Macroscopic temporal studies on the effect of waste plastic materials on anaerobic digestion of raw vegetable market wastes: experiment and modelling

    Rapid urbanisation of the human society has resulted in increasing quantities of municipal solid wastes (MSW). One significant component of MSW is waste plastics (WP). Most of those WP are non-biodegradable and impermeable in nature. It is generally advised that these WP should be retrieved and separated before the landfill operation. This includes an additional cost of operation. To date, no ...

  • Accurate Characterization of Polymers and Additives in Personal Care Products and Packaging by Fast-Scanning IR

    You can’t buy anything today without a package. Think about it. Blister packs, cellowraps, shrink wraps, barrier bags, vapor films, UV-blocking films, heat-blocking films, tinted plastics, filled polymers, biodegradable bags, structural plastics, laminated films, moisture barrier films ….. ad infinitum (literally). Industries that manufacture plastics or utilize plastics need to characterize ...

  • Investigations on damping characteristics of a honge oil-based magnetorheological fluid damper

    Magnetorheological (MR) fluid damper is a kind of intelligent control device that can be used to reduce response of a vibrating member instantaneously with very few moving parts, which is essential in most of the mechanical systems, but challenging. In the present work, a prototype of smart damper using MR fluid (MR damper) is designed based on Bingham plastic model and fabricated to conduct ...

  • Break It Down, Build It Up - Sustainable Science Has Roots in ASTM Standards Development

    It was back in the 1980s,” Richard Wool, Ph.D., recalls. “A lot of waste management sites were running out of space. Barges full of garbage were plowing up and down the East Coast with no place to dock. The idea of having biodegradable plastics would address a number of issues like getting rid of the trash and cleaning up marine waste, which was becoming a huge issue at the ...

  • Investigations into the possibility to compost paraffincoated packaging materials

    Utilisation of biodegradable materials is indispensable for effective economic operation (Soyez, 1998). However, the requirements to be met by the application characteristics sometimes prevent use of such materials. For example, packaging materials for foodstuffs, where protection of the contents is the predominant aim, are required to display hydrophobic properties. Paraffin-coated papers have ...

  • Home composting of organic waste - part 2: effect of management practices

    Home composting (HC) can produce safe compost if properly managed, while reducing municipal disposal costs. This project investigated the sanitary and safety impact of HC management (with/without bulking agent, batch/weekly feeding, with/without regular mixing) using the Plastic (P) and Wood (W) bins, the Rotary Drum (RD) and the Ground Pile (GP) filled with equal wet volumes of food waste (FW) ...

  • Managing Compostable Bags At Anaerobic Digestion Plants

    The highest and best use for treating residential food waste is through source separation, sending organics first to anaerobic digestion (to capture energy), followed by aerobic composting (to return nutrients to the soil). Sending food waste to anaerobic digestion (AD) facilities requires appropriate tools and planning for capturing high volumes of material with low contamination. Compostable ...

  • Biopiles

    Biopile treatment is a full-scale technology in which excavated soils are mixed with soil amendments and placed on a treatment area that includes leachate collection systems and some form of aeration. It is used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance ...

  • Composted Woody Materials Become Erosion Control Product

  • Preparing the way for commercial organics recovery

    The Planning for a source-separated commercial organics program began in California's Santa Cruz County in 2001. Businesses were surveyed to determine if there was sufficient interest in separate collection of food, food-soiled paper and wax-coated cardboard to supply a collection route. Many restaurants, markets and residential facilities responded enthusiastically to the idea of collection and ...
