Abstract

The treatment performance of two‐stage secondary treatment consisting of a trickling filter followed by activated sludge process for treatment of combined municipal and industrial wastewater is determined. The municipal wastewater treatment plant is located in Solon, Ohio, where the treatment units include grit tanks, primary clarifiers, trickling filters, aeration tanks, secondary clarifiers, tertiary filters and chlorine contact tanks. The treatment performance data for a 12‐month period in 1989 was evaluated. The average total plant flow was 2.82 MGD (millions gallons per day) which consisted of 2.19 MGD industrial wastewater and 0.63 MGD domestic wastewater. Raw wastewater was of a high strength mainly due to the contribution from industrial sources. After different degrees of treatment the values of total suspended solids (TSS) and biochemical oxygen demand (BOD) met US Environmental Protection Agency standards. This plant has good treatment performance with 99 per cent BOD and 98 per cent TSS removal efficiencies.

Abstract

Evaluates the effect of bioaugmentation on the activated sludge treatment of food wastewaters including those containing potato, starch, sugar and milk. Parameters of study include live liquid microorganisms, dosage, aeration time and wastewater strength. Concludes that bioaugmentation with addition of live liquid micro‐organisms improves total organic carbon (TOC) removal efficiency and reduces sludge production. Aerobic bioaugmentation is effective in TOC removal from potato, sugar and milk wastewater but not effective in the case of starch wastewater.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract

Purpose

The purpose of this paper is to measure food loss and waste by material flow analysis (MFA) tool. Applying this methodology, the authors estimate wastage-related losses and discuss opportunities for more circular and sustainable practices in the Italian potato industry.

Design/methodology/approach

MFA is applied to two specific typologies as follows: ready-to-eat (chips) and dried potato products produced in Italy. The analysis refers to the year 2017 as the complete dataset useful for this study includes measurements until this year. A bottom-up and top-down mixed approach is applied, and functional unit refers to 1 t of potatoes consumed as final product.

Findings

MFA is applied to quantify and qualify material balance associated with 1 t of potatoes consumed as final product. In Italy, in 2017, more than 22,000 t of fresh tubers were lost, including 3,500–4,800 t of starch, equivalent to 52,800–72,600 GJs. Moreover, fewer than 23,000 t of skins and scraps were produced within industrial plants, not available for food but suitable for animal feed (dry skins are an excellent carbohydrates source in cattle and poultry feed), starch industry and bioenergy production (biogas and/or bioethanol).

Originality/value

This research is one of the few studies proposing MFA methodology as a tool to measure food waste. This analysis shows its utility in terms of food waste quality/quantity evaluation, supporting both company management and policymakers.

Abstract

Daniel and Titman (1997) contend that the Fama‐French three‐factor model’s ability to explain cross‐sectional variation in expected returns is a result of characteristics that firms have in common rather than any risk‐based explanation. The primary aim of the current paper is to provide out‐of‐sample tests of the characteristics versus risk factor argument. The main focus of our tests is to examine the intercept terms in Fama‐French regressions, wherein test portfolios are formed by a three‐way sorting procedure on book‐to‐market, size and factor loadings. Our main test focuses on ‘characteristic‐balanced’ portfolio returns of high minus low factor loading portfolios, for different size and book‐to‐market groups. The Fama‐French model predicts that these regression intercepts should be zero while the characteristics model predicts that they should be negative. Generally, despite the short sample period employed, our findings support a risk‐factor interpretation as opposed to a characteristics interpretation. This is particularly so for the HML loading‐based test portfolios. More specifically, we find that: the majority of test portfolios tend to reveal higher returns for higher loadings (while controlling for book‐to‐market and size characteristics); the majority of the Fama‐French regression intercepts are statistically insignificant; for the characteristic‐balanced portfolios, very few of the Fama‐French regression intercepts are significant.
