Composting fiber

Bagasse food service products can be a replacement for Styrofoam and paper products. PLA and PHA coatings can provide a water barrier for bagasse and paper products. This can provide a compostable fiber product for disposable plates, containers, and food packaging. 

In developing countries, additional advantages of using CWs can be obtained. They may provide economic benefits and could encourage small communities to maintain natural wastewater treatment systems. The production of plant biomass can provide economic returns to communities through production of biogas, animal feed, compost, and fiber for paper according to the type of pollutant.46... 

These results suggest that pure aromatic polyesters may function like the long-lived components in humus and may provide useful properties as a soil additive. Grass sod growing studies using municipal-waste-derived compost in combination with chopped plastic fibers demonstrated improved growing rate and root structure development to accelerate sod production. 

Always use natural fibers such as twine and raffia for tying up plants. They are less likely to strangle a plant than plastic or wire, and can safely be composted. To avoid eye injuries, top canes with purchased, or homemade, cane-toppers. 

Copolymers of polyethylene terephthalate (PET) with nonaromatic acids, poly(ethylene ethers) or hydroxy acids have been blended with starch to produce compostable products such as fibers and films.60 Starch contents up to 80% by weight are claimed. 

PLA may be fabricated into film for packaging and is also made into fibers useful for carpeting (24). PLA is indeed biodegradable, but only under controlled composting conditions. Biodegradation of poly (lactic acid) requires temperatures of about 140 °F for many days to insure decomposition, ultimately into CO and water. Unfortunately, such conditions are not typical of landfills (3) or of most backyard compost heaps. Hence, even plastic bags made from PLA will not quickly disappear from the natural environment. Anaerobic decomposition of PLA results in liberation of methane, an even more potent greenhouse gas than CO (25-28). 

The plants in the container will then develop two separate root systems. The upper root system will use any hydroponic medium you wish other than lava rock, which is used on the bottom half. I recommend that you use rockwool, coconut fiber, composted bark, Oasis fiber, peat perlite, and vermiculite, or my standard suggested "soil" formula for the upper medium layer. You may use... 

Other lignin applications of NIR included research on flax fiber [148], compost prepared from wheat straw and chicken litter [149], hard red winter and spring wheat [150], and degradation of plant cell walls by white-rot fungi [151]. 

PP polypropylene yogurt containers, grocery bags, carpet fiber, food wrap, luggage compost bins, curbside recycling bins... 

Natural fibers will rot away. You can even put discarded clothes on a compost heap. 

Diverse starch-based products are available on the market. Eor example, potato-starch + CaCOj and wood fiber are used by EarthShell to manufacture readily compostable fast-food containers. Starch + PP is used by Moldsmiths to produce therapeutic dog-bones [Schut, 1996]. 

V., Dow Chem. Co., Mitsui Toatsu Chem., Ltd., Neste Oy) Poly-lactic acid (PLA) for thermoforming, blow molding, extrusion of fibers and films. The available products include compostable bags, food containers, cafeteria plates, cutlery, medical and pharmaceutical articles,... 

When horse manure is used as the basic starting ingredient, the compost is considered a "horse manure compost" whereas "synthetic compost" refers to a compost using no horse manure. Straw, sometimes mixed with hay, is the base ingredient in synthetic composts. Because straw is low in potassium and phosphorus, these elements must be provided by supplementation and for this reason chicken manure is the standard additive for synthetic composts. No composts are made exclusively of hay because of its high cost and small fiber. In fact, mushroom growers have traditionally used waste products because they are both cheap and readily available. 

The length of time needed for pre-wetting varies according to the condition of the starting materials. Generally 3 days for horse manure and 5-1 2 days for a synthetic compost is sufficient. The pre-wetting time for a synthetic compost can be shortened if the straw is mechanically chopped, but care should be taken that the fibers do not become too short. 

Throughout the composting process, the size of the pile varies depending on the physical condition of the straw, which provides the pile s basic structure. The structure of the compost refers to the physioal interaction of raw materials, especially the straw fibers. As the straw degrades and The ti-bers flatten out, the structure becomes more dense and the airflow is restricted. The pile becomes fTioire compact and its size is reduced accordingly. Initially the fresh straw allows for generous air penetration which convects away heat and slows microbial action. To counteract this heat loss, the P" pile should be.of maximum size and optimum moisture content at make-up.
