Although the influence of celebrities on public health-related attitudes and behaviors is well established, the specific role that celebrity examples play in shaping health-related social norm perceptions is not well understood. To examine the effect of celebrities on social norm perceptions, young adults were randomly assigned to read news articles about vaping that either featured one of four film stars using a vape pen or did not contain any celebrity exemplar. The presence or absence of a celebrity exemplar did not affect readers' perceptions of vaping social norms. However, three types of audience involvement with the celebrities – liking, parasocial relationship strength, and wishful identification, were examined as mediators of the relative effects of the different celebrities on vaping norm perceptions. The results suggest that celebrities who people like more and those who they wishfully identify with less can wield a greater influence on social norms. PSR strength did not mediate indirect effects of celebrity on social norm perceptions. These findings indicate that celebrities can shape public perceptions of social norms through some types of involvement. [ABSTRACT FROM AUTHOR]

Composting was selected as one of the carcass and manure management options, when poultry population in a region of British Columbia was affected by avian bird flu. Six broiler-breeder farms and five layer farms were involved in on-farm composting of manure from birds that tested positive for avian flu.

Vineyards in four northern California counties are using compost made from commercial and residential food residuals to grow healthier vines and grapes.

Alameda County, California, has launched an incentive program to encourage jurisdiction agencies and private companies to divert organic wastes such as yard trimmings and food residuals from the municipal waste stream. A description of feedstock collection and composting processes is also included.

Composting processes for slaughterhouse offal, such as bones and soft tissue, are described. Due to bans imposed on using offal for livestock feed, implemented to prevent the spread of mad cow disease, composting provides slaughterhouses with waste management options aside from rendering.

The article describes innovations made to the anaerobic digester at Vermont's Foster Brothers Farm to generate methane biogas. The new process, which uses steam, creates gas in less than two weeks, compared to two to three months using previous techniques.

Composting in Oregon's Deschutes National Forest addresses problems of waste management, air quality, and forest fire prevention. The process eliminates the need for incineration, thereby improving air quality, and helps prevent wildfires by reducing underbrush.

Farmers in Florida are including composting as part of their routine agricultural operations. Feedstocks typically include livestock manure and yard waste. The article also discusses challenges to on-site farm composting, such as weather and size and capacity of equipment needed to spread the compost on crop fields.

An overview is presented on new procedures implemented at a reopened compost facility at Marlboro, Massachusetts. The procedures were aimed at facilitating dialogue between city residents and plant officials regarding odor control and noise abatement, which included the installation of a biofilter and silencers placed on exhaust fans.

Hutchinson, Minnesota's program for composting industrial and household food wastes is described. The program, launched in 1998, scans waste for hazardous materials before they are conveyed to temperature and air-flow controlled retention containers where the material is formed into windrows, turned and aged, with the compost screened before marketing.

A description is presented of the trial curbside collection service which is organized by the Chittenden Solid Waste Districts in Vermont, for the collection of yard trimmings, food residuals and paper which is not recyclable.

The Clinton County Compost Facility in Plattsburgh, NY, which experienced significant difficulties during the 1990s, is now being operated by U.S. Filter Operating Services. The full-service operations, maintenance and management deal includes an initial two-year term and three subsequent five-year terms. The plant is now processing 60 tons a day, with its compost recipe including one ton of biosolids to 0.4 tons of mixed sawdust and wood chips. It is anticipated that the facility will produce 70,000 cubic yards a year of finished compost at full operational capacity of 140 wet tons a day of biosolids.

It is widely accepted that there are advantages associated with being able to have a covered area for composting, particularly with regard to moisture control. However, constructing a roofed structure to protect a compost pile can be very expensive, and this is why fabric compost covers have been developed. These covers wick moisture that touches the surface of the fabric into the fabric itself, with the moisture then running through the fabric and dripping off the bottom edge. Compost site managers report that covers also bring benefits in controlling nutrient loss and raising windrow temperatures.

Intervale Compost in Burlington, VT, began receiving food residuals in Aug 1993 and is now a major compost producer using large quantities of food processing residuals. It charges a tip fee of $25/ton for food residuals. Since 1995, it has been processing almost 1 million gal a year of Ben & Jerry's ice cream residuals, with the liquid ice cream being blended with a mixture of bedded horse manure, leaves and sawdust. It started bagging in 1996, and in 1998 it produced 15,000 30-lb bags of compost.

Military bases throughout the US are increasing their involvement with recycling programs for wood wastes and food residuals. Camp Pendleton in California, Otis Air Force Base in Massachusetts, Luke Air Force Base in Arizona and the Air Force Academy in Colorado are some of the military facilities which are actively involved in recycling and composting their wastes. The recycling efforts are made on the basis of practicality and economic sense. While the military bases have their own recycling facilities, they also enter into composting partnerships with nearby farms or sell recyclable materials to various contractors.

Various applications of containerized composting are presented. One is the in-vessel system and vermicomposters utilized at the New York Hospital. The system used four Mini-Comptainers made by Green Mountain Technologies. The composts were later transferred into bigger vessels called Earth Tub, also from the same manufacturer, which is capable of processing 100-200 lbs of food residuals a day. The compost is then removed from the unit after 21 days and placed in windrows for curing. The process produced 2,000 tons/yr of compost priced at $8 per cubic yard.

The number of companies offering on-site custom grinding and turning services for waste materials in the US and Canada continues to rise. New Earth Services of Terrace, BC, for example, offers wood grinding services to ranchers, farmers, sawmills and logging companies, while Austin Wood Recycling of Texas derives a large part of its revenues from supplying tub grinding services to new home construction sites and land clearing operations. Champlain Valley Compost in Vermont serves businesses including dairy, poultry and vegetable farms.

Different marketing strategies have been used by six municipal composting facilities. Palo Alto, California, has chosen Flori Bunda Forest Products to market their compost, which is sold wholesale for $6 per cubic yard. Mecklenburg County, North Carolina, also uses a private contractor called New Solutions, to market their products and they currently sell 6,000 cubic yards each year. Woodbury, Minnesota, has been working with Composting Concepts since 1993. Newspaper advertising is often used to market compost.

Companies that sell compost only by bulk are now branching into selling compost by bags. With this new process of selling, compost is now available to retail costumers as well as to wholesale consumers. One company that profits from selling compost in bags is Glacier Gold which is based in Olney, MT. The company's primary product is lumber and it only branched out to compost to dispose of sawdust. The company has become one of the biggest sellers of compost in bags and by bulks.

Recycling managers are maintaining and adopting new programs to keep up with the continuing problem of waste disposal. The 1987 recycling bill required recycling coordinators to formulate plans regarding proper segregation of garbage for better collection and disposal. Recycling coordinators in such states as Pennsylvania, Texas, Philadelphia, New Jersey, evaluated recycling programs and found them to be effective. New programs are still being adopted to further improve the current state of waste disposal.

Several institutions in the US have installed small scale on-site in-vessel systems for handling their composting operations. Lack of enough space and labor, less equipment requirements, and the control of odors and rodents through contained systems are some of the advantages of these in-vessel systems. Containers are also easier to sell, than open piles of waste. Details of in-vessel systems at the Whiteman Air Force Base, Flushing Hospital and Medical Center, and the Universities of San Francisco and Massachusetts are presented.

Naval Stations and Air Force Bases around the country have developed various innovative recycling programs to divert solid waste from their specific branch and the state in which they are located. The programs at these naval stations and air force bases involve the collection and processing of recyclables, hazardous substances and compost organics generated at the site. A description of the recycling programs at the San Diego and Norfolk Naval Stations, and the three Air Force bases at North Dakota, Texas and California is presented.

Solid waste composting has had several failures and yet projects continue to operate because many people believe recovery to be a better option than incineration or landfilling. Solid waste composting projects are of two types: mixed waste or source separated composting. Most projects in the US use the former method. The latter method involving nonresidential sources represents the strongest growth sector. Composting plants range in size from three tons/day to 250 tons/day. Nine of the 15 composting facilities have been functioning for 5 or more years, while 4 started in 1992.

A survey reveals that municipalities, land clearing companies, lumber mills and other generators of woody materials increasingly utilize private contractors' services to process piles of wood stock at their sites. The contractors using their own equipment for composting and mulching waste materials, also benefit financially from such business. The introduction of portable equipment has sped up the process.

Voluntary and mandatory approaches have been implemented to increase multifamily recycling. Curbside recycling program at the West Cook County in Chicago for multifamilies proved to be cost-effective and has successfully diverted 30% to 50% of the wastes. But less than 20% building owners set up recycling programs. Portland, Oregon, made multifamily recycling mandatory after spending $2.2 million over a period of 6 years to promote it. Torrance, California, follows a voluntary approach, since a mandatory approach was unfeasible due to poor economic conditions.

Food service composting projects, which cover institutional and organic wastes, are growing. The preference for on-site composting is increasing due to cost-effectiveness, reduced legal restrictions and low capital investment needs. Various processing approaches utilize the static pile method, outdoor and indoor windrows, invessel and agitated bay system and vermicomposting. Efficient organic collection and recovery will determine the future of food service composting. Various aspects of food composting, such as storage and handling, and market options for the ready compost are discussed.

The Watershed Agricultural Council is a voluntary organization aimed at improving farm management and being cost effectively protecting the New York City (NYC) water supply located in upstate New York. The project was developed because local farmers wanted locally managed programs instead of regulations. The program involves the evolving Whole Farm Planning/Best Management Approach and developing 10 demonstration projects. The Department of Environmental Protection in NYC is monitoring the project. Municipalities in other towns are following this example to protect water supplies.
